The present application claims priority to Canadian patent application No 2,973,210, filed on July 13, 2017. This document is hereby incorporated by reference in its entirety.

FIELD OF THE INVENTION

The invention relates to a process for producing fuel from a variety of organic material, such as municipal solid waste and/or waste hydrocarbons or a mixture of the two treated simultaneously. The invention also concerns new rotating reactors and apparatus for performing the process, corresponding managing system allowing a continuous optimisation of the process. The inventions also relates to the uses of liquid fuel threby produced.

BACKGROUND OF THE INVENTION

Municipal solid waste (MSW), commonly known as trash or garbage in the United States and as refuse or rubbish in Britain, is a waste type consisting of everyday items that are discarded by the public. "Garbage" can also refer specifically to food waste, as in a garbage disposal; the two are sometimes collected separately. The composition of municipal solid waste varies greatly from municipality to municipality and changes significantly with time. In municipalities which have a well-developed waste recycling system, the waste stream consists mainly of intractable wastes such as plastic film, and non-recyclable packaging materials. At the start of the 20th century, the majority of domestic waste (53% wt.) in the UK consisted of coal ash from open fires. In developed areas without significant recycling activity it predominantly includes food wastes, market wastes, yard wastes, plastic containers and product packaging materials, and other miscellaneous solid wastes from residential, commercial, institutional, and industrial sources. Most definitions of municipal solid waste do not include industrial wastes, agricultural wastes, medical waste, radioactive waste or sewage sludge. The term residual waste relates to waste left from household sources containing materials that have not been separated out or sent for reprocessing.

Living in a growing society that consumes a lot of resources, more and more waste is being generated every day. This waste comes in many forms, such as waste hydrocarbons, MSW, etc., but needs to go somewhere once used. Although there are current solutions, such as composting and recycling, which reduce the amount of waste that must be disposed of, they do not have enough of an impact in order to decrease the production of waste to a point where it is not a problem. There is a limited capacity in landfills, and other methods of disposal, for example incineration, pyrolysis and transformation of MSW to refuse-derived fuel, all have their problems.

PRIOR ART

1. MSW Management Solid wastes are any discarded materials. They can be solid, liquid, semi -solid or containerized gaseous material. In the light of a survey conducted by World Watch Institute, the total volume of municipal solid waste (MSW) is about 1.3 billion tons per year in the world (MSW is measured before disposal, so data on it include material that is later diverted for recycling).

The disposal of MSW is a matter of increasing concern for governments all around the world. Following are a few ways to deal with MSW.

1.1 Pelletizing of Municipal Solid Waste into Refuse-Derived Fuel

Trash is processed to remove recyclables, such as metals and glass, and unwanted residue and hazardous materials, with the remaining (preferably mostly combustible) positively selected fraction shredded and sent to fiberizing and pelletization or briquetting equipment. The solid pellet or briquette produced from these techniques can be used as fuel to produce heat and is known as Refused-Derived Fuel (RDF). RDFs have many usages, such as being used for heating plant boilers, for the generation of electricity. Due to the special composition of them, they can also be an excellent substitute for fossil fuels.

1.2 Pyrolysis of Municipal Solid Waste

Pyrolysis is a process consisting of the chemical decomposition of organic materials by heat in the absence of oxygen, which produces various hydrocarbon gases and/or other organic vapours. During pyrolysis, the molecules of the object are subjected to very high temperatures leading to very strong vibrations. Therefore every molecule in the object are stretched and shaken to an extent that molecules start to break down. The rate of pyrolysis increases with temperature. Fast pyrolysis of organic material mainly produces liquid fuel known as bio-oil. Slow pyrolysis of organic material mainly produces gases and solid charcoal. Pyrolysis is extensively used in the petrochemical industry and can be applied to municipal waste treatment where organic waste is transformed into combustible gas, liquid fuel and residues.

1.3 Gasification of Municipal Solid Waste

Gasification, similar to pyrolysis, is a process of chemically decomposition of organic materials by heat in the absence of oxygen which produces mainly gasses, such as carbon monoxide, hydrogen and carbon dioxide and char. The temperatures for gasification are higher than those for pyrolysis and therefore the molecules break down into even smaller molecules. The product syngas can be used to either produce heat, which is used to create steam and drive a turbine, thus generating electricity, be used as a fuel in a dedicated gas engine, or be used as a feedstock to form other products, such as ethanol. During gasification, tars, halogens, heavy metals and alkaline compounds can be released, which is bad for the environment. Also, the efficiencies of the electricity production are relatively low.

1.4 Incineration of Municipal Solid Waste

Incineration technology is the controlled combustion of waste with the recovery of heat to produce steam that, in turn, produces power through steam turbines. The incineration process produces two types of ash. Bottom ash comes from the furnace and is mixed with slag, while fly ash comes from the stack and contains components that are more hazardous. Such systems rely on minimum guaranteed waste flows. It indirectly promotes continued waste generation while hindering waste prevention, reuse, composting, recycling, and recycling-based community economic development. It costs cities and municipalities more, provides fewer jobs than comprehensive recycling and composting, and also hinders the development of local recycling-based businesses.

1.5 Dumping of Municipal Solid Waste into Landfills

Landfills may cause numbers of problems. Pollution of the local environment may occur as well, such as contamination of groundwater or aquifers by leakage or sinkholes or soil contamination. Damage can include infrastructure disruption, such as damage to access roads by heavy vehicles. As existing landfills become filled to capacity and it is increasingly costly to site new landfills, the development of alternative disposal methods is becoming essential. In addition, the wastes being buried contains considerable quantities of energy that can replace conventional fossil fuels.

2. Technologies for Municipal Solid Waste Pyrolysis

2.1 Fluidized bed reactor

A fluidized bed reactor for pyrolysis utilises heated granular solid material, usually sand or solid products from pyrolysis, in which the feed material to be pyrolysed is fed into. A heated sweep gas is used to fluidize the heated granular solid material on which pyrolysis reactions occur and to collect the vapours and gasses. A problem with this type of reactor is bed agglomeration, which is the formation of large agglomerates. The formation of these agglomerates decreases mixing and heat transfer within the reactor and may result in defluidization of the bed. The fluid-like behaviour of the solid particles also cause wear on the reactor walls and pipes, which increases maintenance cost. Also, the vapours produced from the pyrolysis must pass through solids above it, and thus possibly picking up contaminants while exiting the reactor.

2.2 Auger reactor

An auger reactor for pyrolysis comprises of one or more screws which continuously mix the feed material to be pyrolyzed and a heat carrier, which is usually sand or steel shot, while also conveying them from the entrance to the exit of the reactor. The heat carrier is heated independently before being introduced into the reactor, near where the feed material is introduced. As the heat carrier and the feel material mix, pyrolysis reactions occur. A sweep gas is used to carry the produced vapours out of the reactor, while the solids and residue are lead out of the reactor from a separate exit. A problem with this type of reactor is that, depending on the feed material, the auger is prone to mechanical clogging due to the accumulation of residue on the screw(s). Also, the vapours produced must pass through solids above it, and thus pick up contaminants while exiting the reactor.

2.3 Plasma reactor First, the material to be gasified is possibly pre-treated to reduce water content and/or remove recyclable material. Then the feed material is fed into the a sealed, air -controlled reactor which heats its contents to extreme temperatures via the use of plasma torches, which produces syngas and slag. The liquid slag is poured off and cooled, while the syngas is scrubbed of impurities and passed through heat exchangers in order to recover some energy. The syngas is then used to produce energy or fuel via chemical reactions or by combustion. Although plasma reactors have potential to produce clean vapours and even destroy hazardous waste, the high energy cost causes little net energy production and both the capital and maintenance costs are very high.

GENERAL DEFINITION OF THE INVENTION

Preliminary definitions:

Municipal solid waste (MSW), commonly known as trash or garbage in the United States and as refuse or rubbish in Britain, is a waste type consisting of everyday items that are discarded by the public. Waste can be classified in several ways but the following list represents a typical classification:

- biodegradable waste: food and kitchen waste, green waste, paper (most can be recycled although some difficult to compost plant material may be excluded);

- recyclable materials: paper, cardboard, glass, bottles, jars, tin cans, aluminum cans, aluminum foil, metals, certain plastics, fabrics, clothes, tires, batteries, etc.;

- inert waste: construction and demolition waste, dirt, rocks, debris, ;

- electrical and electronic waste (WEEE) - electrical appliances, light bulbs, washing machines, TVs, computers, screens, mobile phones, alarm clocks, watches, etc.;

- composite wastes: waste clothing, Tetra Packs, waste plastics such as toys;

- hazardous waste including most paints, chemicals, tires, batteries, light bulbs, electrical appliances, fluorescent lamps, aerosol spray cans, and fertilizers; and

- toxic waste including pesticides, herbicides, and fungicides.

Organic material· means organic matter, organic material, or natural organic matter (NOM) refers to the large pool of carbon-based compounds found within natural and engineered, terrestrial and aquatic environments. It is matter composed of organic compounds that has come from the remains of organisms such as plants and animals and their waste products in the environment. Organic molecules can also be made by chemical reactions that don't involve life. Basic structures are created from cellulose, tannin, cutin, and lignin, along with other various proteins, lipids, and carbohydrates. Organic matter is very important in the movement of nutrients in the environment and plays a role in water retention on the surface of the planet. Organic material may also include hydrocarbons and/or MSW or a mixture of the two, including plastics.

Contaminants: In MSW, the contaminants are non-combustible material and/or non-organic material, for example metals, stones and glass. Liquid fuel: are combustible or energy -generating molecules that can be harnessed to create mechanical energy, usually producing kinetic energy; they also must take the shape of their container. It is the fumes of liquid fuels that are flammable instead of the fluid. Most liquid fuels in widespread use are derived from fossil fuels;

however, there are several types, such as hydrogen fuel (for automotive uses), ethanol, and biodiesel, which are also categorized as a liquid fuel. Many liquid fuels play a primary role in transportation and the economy. Liquid fuels are contrasted with solid fuels and gaseous fuels.

Agglomerate: are coarse accumulations of solid particles and/or blocks. In the meaning of the present invention they are accumulations of particles obtained from the solids present in MSW and that have been previously transformed into smaller particles, for example by mechanical means. Agglomerates are typically poorly sorted, may be monolithologic or heterolithic, and may contain some blocks of various rocks.

Pellets: means a small rounded compressed mass of substance, that may, for example, be in the general form of cylinders.

Used Lubricating Oil (ULO): are oils or greases that were used as lubricants, usually in engines, and were discarded. Examples would include car engine oils, compressor oils, and diesel engine oils among others.

Lubricating oils generally contain additives, which are carefully engineered molecules added to base oils to improve one or more characteristic of the lubricating oil for a particular use. Used lubricating oil is classified as a hazardous product in many jurisdictions because of its additives and contaminants.

Organic vapour: is the vapour produced from the pyrolysis of the feed material entering the rotating kiln. The components of the organic vapour may include hydrocarbons and may also comprise of only hydrocarbons.

Bio-oil: is the product from the condensation of the organic vapour. Bio-oil also includes specific chemicals obtained from the condensed organic vapour, which may be separated individually from the other components of the condensed organic vapour.

Liquification : means to increase the liquid fraction of a material which has at least a solid fraction. The resulting material after liquification is then considered a liquid and may or may not have entrained solids and/or gasses.

Substantially non-re active gas : is a gas such as nitrogen, recycled reaction gas, carbon dioxide or water steam that does not affect or enter into the thermal processing or that does not substantially combine with either the feed or reaction products in the reactor operating range, for example in a temperature range ranging from 350 to 850 degrees Celsius, in a temperature range up to 700 degrees Celsius, preferably up to 525 degrees Celsius.

Waste oils are oils or greases that are discarded. They include used lubricating oils (ULO) as well as a wide range of other oils such as marpol, refinery tank bottoms, form oils, metal working oils, synthetic oils and PCB-free transmission oils, to name a few.

Consistent shapes: means shapes so they can stay on the narrow shelves and/or each other, while protecting the reactor wall from direct contact with the relatively cold feed. In the meaning of the invention, the expression consistent shapes also means:

- a multiplicity of physical elements having substantially the same form;

- a multiplicity of physical elements having substantially the same form and substantially the same size;

- a multiplicity of physical elements having substantially the same size, provided those forms are compatible in such an extent that are globally symmetrical and stay substantially constant during rotation inside the rotating kiln; and

- a multiplicity of physical elements having shapes that permit that plates sit upon each other, preferably in such a way that there is no space or substantially no space between them.

Dynamical wall· the multiplicity of plates of consistent shapes results, because of the rotation, in a continuously reconstructing wall.

Thermal processing/thermally treating: is preferably any change in phase and/or composition, and/or reactions initiated or facilitated by the application, or withdrawal, of heat and/or temperature. Examples of thermal processing include evaporating, cracking, condensing, solidifying, drying, pyrolyzing and thermocleaning. In the meaning of the invention the expressions Thermal processing/thermally treating preferably exclude combustion and more specifically apply in the context of indirectly fired rotating kiln.

The height of a shelve: is the distance between the attachment point of the shelve on the reactor wall and the end of the shelve directed to the center of the reactor.

The width of a shelve : is the measurement of the distance between the two sides of the shelve on a direction perpendicular to the height of the shelve.

Sweep gas : is any non-reactive or substantially non-reactive gas. Preferably it is an inert gas such nitrogen, recycled reactor non-condensable gas or water steam. It was surprisingly found that such gas not only have as sweeping effect in the reaction zone of rotating operating reactor, but may help control the pressure in the reactor, may increase the safety in plant operations, may help control the reactions in the reactor and globally may improve the efficiency of the process. For example, the sweep gas is a gas stream that may additionally serve in various the following functions such as:

- when injected into the reactor feed line, the sweep gas changes the density of the total feed stream; it changes the flow regimes within the feed line and/or nozzles, which results in lower incidence of fouling and plugging of the piping and spray nozzles, and in improved spray patterns; further, the sweep gas favours atomization of the organic liquid feed stream before the organic liquid reaches the reaction sites on the hot plates, and/or

- if introduced into the liquid feed at temperatures above that of the organic liquid feed stream, it will increase the feed stream temperature and reduce the energy, or heat, provided by the kiln, and/or

- it reduces the organic vapour’s and/or organic liquid's residence time in the reactor, by sweeping the organic vapours out of the reactor soon after they are formed, thereby reducing the incidence of secondary reactions, or over-cracking, resulting in higher liquid yields and more stable liquid product bio oils, and/or

- the sweep gas present in the reactor reduces the organic vapour's partial pressure, and favours the vaporization of the lighter organic fractions, for example gasoil and naphtha, in the feed and products; this also reduces over cracking in the lighter fraction and increases the stability of the bio-oil liquid products, and/or

- the sweep gas helps to stabilize the pressure in the reactor, and/or

- when steam or nitrogen are used, the sweep gas reduces the risk of fires in the event of a leak in the reactor or in the downstream equipment; it will disperse the combustible vapours escaping and, hopefully, keep the combustible vapours from igniting, even if they are above their auto-ignition point, and/or

- it can also be part of the stripping gas stream in the product distillation unit.

In order to faciliate reading of the present description and of corresponding Figures, following table of correspondance is thereafer provided.

Shelves: are physical objects comprised of one or multiple pieces which extrude from the reactior wall and which serve the functionality of stopping the downwards sliding of reaction supports as the reactor rotates, thus pushing the reaction supports up the reactor wall as the reactor rotates. A series of shelf pieces (for example shelf Is, shelf 2s, shelf 3s) linearly alligned act as a shelf. A shelf may comprise of one or many stoppers and/or one or many guides. A shelf may be comprised of one or many objects which serve both as guides and as stoppers.

Stoppers: are the parts of the shelves on which reaction supports rest as they ascent the reactor wall during the reactior’ s rotation. For example, stoppers may be in the form of cylinders, rectangles, parallelograms, or any deformed variations of the previously mentionned shapes. Stoppers may also push solid matial which cannot slide and/or roll past the stoppers during the rotation of the reactor. Guides: are the parts of the shelves which serve as a device for steadying or directing the motion of something, particularly to direct the movement the solid material which is fed into the reactor and/or which is removed from reaction supports. They have at least one side which is angled downwards from the horizontal axis, towards the side of the reactor in which shovels are located. As the reactor turns, solid material slides and/or rolls on the reactor wall and comes in contact with the guides. Upon contact with the guides, the solid material slides and/or rolls on the guides, which changes their momentum and directs the solid material towards the shovels. The guide closest to the shovels in each section of the reactor also has the functionality of directing the movement of the solid material from one section to another. The guide(s) which is(are) in contact with the shovel(s) direct the movement of solid material into the shovel(s).

Separator pieces: are physical pieces located within the reactor and attached to the reactor wall. When placed in a series, along the circumference of the reactor wall, separator pieces act as a separator, which has the function of preventing the movement of reaction supports between sections of the reactor.

Separator pieces provide a surface on which reaction supports can rest on and/or bounce off of dining the rotation of the reactor. Due to the rotation of the reactor and the pushing action provided by stoppers, reaction supports fall from the reactor wall and may be directed towards separator pieces. In this case, the movement of reaction supports are blocked by the presence of separator pieces. Due to the presence of a series of separator pieces, which make up an entire separator, the reactor is split into sections, in which reaction supports cannot leave during the normal operation of the reactor. (A VERIFIER PAR LOUIS)

Reaction supports: are physical objects in the reactor which serve as reaction sites for pyrolysis reactions. They move around in the reactor and slide over eachother during the rotation of the reactor. Solid material gets deposited on the reaction supports due to pyrolysis reactions. As reaction supports slide over each other, they scrap each other and remove at least part of the solid material deposited on their surfaces and/or on other surfaces in the reactor. Reaction supports may, for example, have the shape of rectangular plates or triangluar plates. Within the text, mentions of plates refers to reaction supports and they can be used interchangably.

Detailed description of preferred embodiments of the invention

Starting material - The starting material for the process is MSW and/or waste hydrocarbons or a mixture of the two, wherein the MSW is preferably obtained after composting and/or recycling. The composition of MSW varies drastically throughout the year and with respect to location. Please refer to Figure 26 for an example of the general composition of MSW in the United-States in 2012 before and after recycling and composting. The starting material may also be an oily feed material, even those with a high CCR and/or with high viscosity.

Preparation of agglomerate

Preparation of pellets

Material suitable for pelletization is positively selected from the starting material, inter alia after elimination of at least part of the stones and metallic parts with a small amount of residue set aside for disposal. The materials suited for fuel pellet production are shredded, fiberized and eventually stored in storage silos. For example, In primary shredding, the materials are delumped into 25-40mm size to enable easy drying and separation. For example, delumped materials are dried from 50% wt. moisture to 25% wt. moisture, either on a paved sun drying yard or in a mechanical dryer. Dried waste materials are passed through a rotary sieve for separation of fine dirt and sand; fine materials can be sent as soil conditioner for further processing. Screened waste materials is passed through density separation phase in air density separator. Heavy particles are rejected and sent for dumping. Light fraction is passed through a cage mill for further size reduction with hot air for faster drying and moisture is reduced from 25% wt. to 15% wt. Dried combustible material having 25-40mm size is refuse-derived fuel and its calorific value is about 3000 kCal/kg. Refuse -derived fuel can be ground further in a secondary shredder for making it suitable for palletisation, then it can be later combined with high-BTU admixture materials such as carpet waste, poly film or other acceptable plastic derivatives. They are transferred through pellet mills to produce the final fuel pellet with different diameters i.e. 10mm to 25mm, suitable for different uses. These fuel pellets are hard and odorless, can be stored for up to three years without significant biological or chemical degradation, and due to their increased bulk density, are more durable and can be more easily transported. High bulk density and regular size makes its transport, storage, conveying and combustion easier as compared to other fuels. Parameters of refuse-derived fuel pellets are for example as follows:

Parameter Concentration (% wt.) Carbon 40.12

Hydrogen 3.31

Sulphur 0.41

Nitrogen 0.3

Oxygen 25.06

Moisture 14.7

Ash 16.1

Briquetting

Before briquetting, municipal waste has to be processed for size reduction, preferably adding binder agents and reducing the moisture content. In general, the moisture content, fraction size, pressing temperature, and compacting pressure of compressed waste are the most important parameters to manufacture briquettes with acceptable quality. The pressing temperature and compacting pressure depend on the type of briquetting machine used. Fraction size has great influence on the briquetting process. The coarser the fraction is, the higher compacting power is needed for briquetting. Briquette has lower homogeneity and stability. By increasing the fraction size, the binding forces inside the material decrease which effects on faster decay by binning.

Preparation of powders

The physical transformation of municipal waste into powder is done, for example through the use of a pulverizer. As a matter of example, first the material suitable for pulverisation is positively selected, inter alia after elimination of at least part of the stones and metallic parts with a small amount of residue set aside for disposal. Once properly selected, the material suitable for pulverisation enters a hammermill, which is a steel drum equipped with a rotating shaft on which hammers are mounted. As the shaft rotates, the hammers swing and crush the material entering the hammermill. As the material is crushed, its size is reduced and, once the material is small enough, it passes through a screen to be further processed. Once the crushed material exits the hammermill through the screen, it is conveyed, for example, with an auger and enters a dryer which reduces the moisture in the material. The dried material then enters a pulverizer, for example the TORXX KINETIC PULVERIZER commercialised by Marathon Equipment on the date of June 15 ^th 2017, which grinds the material entering it into particles with dimensions, for example, smaller or equal to 3 mm.

Hydrothermal liquefaction also named (HTL) is a thermal depolymerization process used to convert wet biomass into crude-like oil -sometimes referred to as bio-oil or biocrude- under moderate temperature and high pressure. The crude-like oil (or bio-oil) has high energy density with a lower heating value of 33.8-36.9 MJ/kg and 5-20 % wt. oxygen and renewable chemicals.

The reaction usually involves homogeneous and/or heterogeneous catalysts to improve the quality of products and yields. Carbon and hydrogen of an organic material, such as biomass, peat or low-ranked coals (lignite) are thermo-chemically converted into hydrophobic compounds with low viscosity and high solubility. Depending on the processing conditions, the fuel can be used as produced for heavy engines, including marine and rail or upgraded to transportation fuels, such as diesel, gasoline or jet-fuels.

In the framework of the presently application, this expression correspond to the step wherein agglomerates are at least partially in a liquid feedstock to be submitted to thermal treatment in a rotating kiln.

Liquefaction and dehydration of the feed - The resulting pre-treated starting material then enters a liquefaction vessel to be liquefied, thus increasing the liquid fraction of the said feed material. Advantageously, at least part of the liquid in the liquefaction vessel is taken from a unit downstream from the pyrolysis reactor and preferably consists of 1 to 50 weight percent of the liquid, more preferably 5 to 40 weight percent of the liquid, more preferably 10 to 30 weight percent of the liquid, more preferably 15 to 25 weight percent of the liquid, more preferably 18 to 22 weight percent of the liquid.

The pressure in the vessel is preferably between 0.1 to 10 atmospheres, more preferably between 0.3 and 5 atmospheres, more preferably between 0.5 and 2 atmosphere. Upon heating, some of its components melt, others vaporize, others remain solid and others decompose to form vapours and solids. By heating the pre-treated starting material, some of the water will evaporate and will exit the vessel, along with other lighter vapours, thus effectively dehydrating the material to be fed into the kiln. Advantageously, the liquefaction vessel is equipped with a self-refluxing condenser in order to condense some of the vapours exiting the vessel. The methods of heating the vessel are, for example, by introducing a flame near the walls of the vessel, by the injection of superheated steam into the vessel, by the transfer of heat with a thermal fluid, by electromagnetic radiation, by an electric heat source, or by coil visbreaking, or any combination of at least two of these. Coil visbreaking is achieved by circulating the fluid within the vessel though heated pipes via the use of a pump, wherein said pipes may, for example, be heated by any one or any combination of the methods listed above. After the liquefaction step, the resulting material is deemed liquid and may or may not contain entrained solids and/or vapours.

The sweep gas stream is any non-reactive, or a substantially non-reactive, gas that is introduced with the reactor feed stream, or via another injection nozzle, into the reactor via a separate nozzle. Examples of sweep gas streams include water steam, nitrogen and reaction non-condensable gas at normal conditions of atmospheric pressure and 15 degrees Celsius. By performing the process according to the present invention it has been surprisingly found that the sweep gas stream may additionally also serve a variety of functions such as, but limited to, the following functions:

- when injected into the reactor feed line, the sweep gas changes the density of the total feed stream; it changes the flow regimes within the feed line and/or nozzles, which results in lower incidence of fouling and plugging of the piping and spray nozzles, and in improved spray

patterns; further, the sweep gas favours atomization of the organic liquid feed stream before the organic liquid feed reaches the reaction sites on the hot plates, and/or

- if introduced into the liquid feed at temperatures above that of the organic liquid feed stream, it will increase the feed stream temperature and reduce the energy, or heat, provided by the kiln, and/or

- it reduces the organic vapour’s and/or organic liquid's residence time in the reactor, by sweeping the organic vapours out of the reactor soon after they are formed, thereby reducing the incidence of secondary reactions, or over-cracking, resulting in higher liquid yields and more stable liquid product bio oils, and/or

- the sweep gas present in the reactor reduces the organic vapour's partial pressure, and favours the vaporization of the lighter organic fractions, for example gasoil and naphtha, in the feed and products; this also reduces over cracking in the lighter fraction and increases the stability of the bio-oil liquid products, and/or

- the sweep gas helps to stabilize the pressure in the reactor, and/or

- the sweep gas helps to keep the velocity of the vapours exiting the reactor stable, improving the solids- vapour separation efficiency in downstream equipment;

- when steam or nitrogen are used, the sweep gas reduces the risk of fires in the event of a leak in the reactor or in the downstream equipment; it will disperse the combustible vapours escaping and, hopefully, keep the combustible vapours from igniting, even if they are above their auto-ignition point, and/or

- it can also be part of the stripping gas stream in the product distillation unit.

As seen in Figure 50, the organic liquid feed stream (112) is introduced into the reactor through one or more spray nozzles (114) within the rotating kiln (113) as described in the Canadian Patent Application No. 2,704, 186. The kiln rotates within a combustion chamber (115) which is fired by temperature controlled burners (116). The rotating kiln has internals and is kept at the desired temperature such that the vaporization and thermal cracking of the organic liquid feed stream takes place before the liquid can reach the kiln wall.

The reactor operates at a positive pressure up to 100 kPa(g). The kiln operating temperature is determined by the quality and quantity of the reactor feedstock, and by the quality and quantity of the desired products, and by the reactor volume or residence time available. It can vary from 400 degrees Celsius to 700 degrees Celsius for MSW feeds, and around 500 degrees Celsius, when waste plastics are treated.

The organic vapours and the coke particles exit the reactor and enter a box and/or cyclone (117) separators where the solid particles are removed from the organic vapours. In a preferred mode, the vapour-solids separators are in a heated chamber (118) or heat traced to prevent dew point condensation and plugging of the equipment. The coke (131) and other solids drop by centrifugal force and gravity, they are cooled (130) and sent to storage. Normally, the coke and other solids exiting the reactor are non-leachable.

The organic vapours enter a flash drum (119) and self-refluxing condenser, or scrubbing tower (120) assembly, where the remaining coke is removed. The heavy bio-oil from the bottom of the flash drum (129) can be mixed with the distillation column bottoms and/or recycled to the reactor feed and/or sent to storage and sold. The vapours from the reactor are partially cooled (132) and enter the product separation unit (121). The vapours exiting the top of the main distillation column are cooled (122) and are separated in a three phase accumulator to yield the product gas (123), naphtha (124) and water (125). The water is sent to storage or to the water treatment unit. After treatment, it can be re-used in the steam generation unit. Some of the naphtha is used as reflux to the main distillation column, the rest is sent to storage. It may be used as fuel in the plant. The gas is consumed on site as fuel in the plant.

The bio-diesel fraction (127) is pulled as a side cut, possibly through a stripper, cooled (126) and sent to storage.

The column bottoms or heavy product (128) can either be recycled to the liquifying vessel and/or to the feed entering the kiln, or cooled and sold as de-metalized, low sulphur, heavy fuel bio-oil.

Advantageously, the a process is using an indirectly fired rotating kiln (1), represented on Figures 1 and 2, having preferably the following dimensions 8' by 20' containing a charge of 1100 metal plates (2) that are lifted by one or more narrow shelves (3) as the reactor rotates at a speed comprised between 0.5 and 10 rpm. The shelves are wide enough to hold two plates: one against the wall, and a second one against the first plate. The plates are flat pieces of metal of regular shapes. The heat (5) coming through the reactor wall heats the plates as they are dragged and lifted against the reactor wall by one or more narrow shelves. As the rotation continues, the plates fall off the shelves or off the plates below them, and flip as they fall, presenting the hot surface to the organic liquid feed jet (4) projected unto the plates (5) by a nozzle preferably spraying the organic liquid feed in a rectangular pattern.

The plates carry the heat from the reactor walls and provide a hot surface where the reactions take place. The plates are lifted and kept against the reactor walls by shelves (3). Depending on the thickness of the plates, the shelves can be designed to hold one, two or more rows of plates. As the kiln rotates, the plates fall off the shelves or off the plates below, presenting the face that was against the reactor wall to the organic liquid spray.

As they slide over each other, the metal plates become a surface that protects the reactor walls from direct contact with the relatively cold organic liquid spray and from the resulting failure due to the thermal shock. Also, as they slide down the reactor, the plates scrape the reactor walls and each other clean of coke and avoid bridging of the depositing coke. The coke released is entrained out of the reactor with the organic vapours or is removed by the scoops, hopper and solids exit.

The shelves are attached to the reactor walls with clamps (6), represented on Figures 4 and 5, to reduce stress due to the differential thermal expansion between the reactor walls and the shelves. The clamps are spaced in such a way that, even at the hottest reactor temperature, the shelves are strong enough to support the hot plates on them. Depending on the spacing between the shelves, there may be only one double row of plates per shelf or several rows one on top of each other. Both the plates and shelves increase the heat transfer area from the heat source to the reaction site.

The clamps (6) are shaped like a T as represented in Figures 4 and 5. The base of the T (7) is welded to the rotating kiln walls. The cross bar or top of the T (8) is U shaped to receive the shelve (3) ends, leaving room for the thermal expansion of the shelves, both longitudinally and perpendicular to the reactor wall. Bolts (9) close off the U brackets and keep the shelves from falling out of the brackets. The branches of top of the T (6) are wide enough to allow for the thermal expansion of the shelves within them, while providing strength and support for the load of 1, 2 or more layers of the metal plates along the full length of the shelves in the reactor, and as many rows as the spacing between the shelves will accommodate.

Scoops (10) are attached to the kiln wall at the exit end of the kiln to remove heavier coke that may have deposited on the bottom of the kiln. The scoops are pipe sections with one end closed, and the other end cut on a slant, to allow any organic vapours to escape before the coke falls into the hopper (11). The scoops are sized small enough so that the metal plates cannot enter with the coke. As the reactor rotates, the scoops turn upside down and dump their load of coke into a hopper mounted on the solids exit tube (12). To ensure that none of the plates block the coke exit from the reactor, the hopper has a metal grid (13) that will deflect any plate towards the bottom of the kiln. The solids exit tube (12) has a screw conveyor (15) to push the coke out of the reactor. The solids exit tube can be above the vapour exit tube (14), within the vapour exit tube, below the vapour exit, or even at separate ends. There must be at least two exits from the kiln to ensure that the reactor exit is never obstructed. In normal operation, the coke will exit the reactor mostly through the vapour exit (14). The scoops are required when the feed to the kiln is interrupted and there is no vapour to carry the coke out, or when there is a surplus of coke, or the coke is wet with organic vapours.

The reactor is an indirectly fired rotating kiln, heated by the burner (5), and containing a charge of metal plates that carry the heat from the reactor walls and provide a hot surface where the reactions take place. The plates are lifted and kept against the reactor walls by one or more shelves, wide enough to hold two plates. As the kiln rotates, the plates fall off the shelves, presenting the face that was against the reactor wall to the organic liquid spray. The metal plates protect the reactor walls from thermal shock, and scrape the walls and each other clean of coke. The shelves are attached to the reactor walls with clamps to reduce stress due to differential thermal expansion between the reactor walls and the shelves. Both the plates and shelves increase the heat transfer area from the heat source to the reaction site.

In the test apparatus, MSW mixed with used oil or other oils are sprayed into a horizontal or slanted rotating kiln 10' in diameter and 8' long in order to thermally crack and vaporize the organic liquid feed or the chemicals within it. The kiln has 4" fins welded in continuous spirals, 8" apart, to the inside of the kiln walls. A 1" wide shelf is attached to the fins, and a charge of 4" equilateral triangular metal plates is added.

As the kiln rotates, the shelf pushes and raises the blades along the reactor wall. As they reach just past the 5' height, they flip as they fall at the top of their rim, presenting their hot side to the organic liquid being sprayed on them.

Upon contact with the hot plates, the organic liquid is thermally cracked and/or vaporized. The coke formed is either entrained with the vapours out of the kiln or it deposits on the plates. The plates, sliding against the reactor wall or on each other, scrape the coke free, and it is entrained out of the reactor with the vapours. Most of the coke exits the reactor with the organic vapours, the residual coke is removed by the scoops, hopper and solids exit.

Four scoops are welded to the reactor wall at the exit end. They are made from 4" piping, 6" long, with one end plugged, and the other end cut on a slant. A hopper protected by a metal cage above it, receives the coke dumped by the scoops. The cage deflects any scooped up plate back into the reactor. The hopper receives the coke and drops it into the coke exit tube. A screw conveyor, on the bottom of the coke exit tube, carries the coke out of the reactor.

Figures 10, 12, 13 and 14 are illustrations of the apparatus adapted for different feedstocks.

Figure 10 shows a vertical cross section of a reactor in the horizontal position. The reactor actually has four shelves, but only two are shown here (20). The other two shelves would be on the section not shown. The feed enters the reactor in pipe (21), and is projected unto the hot plates (23) by spray nozzles (22). A possible feed for this reactor would be an organic liquid such as MSW mixed waste oils.

Figure 10A is also a vertical cross section (201) of the same reactor as in Figure 10 with the exception that two of the shelves (203) are replaced with a row of stoppers, dowels or protuberances (202) that support and lift the plates (204). The rows of stoppers serve the same functions as the shelves: they lift the plates, keeping them against the reactor wall.

In a preferred embodiment of the invention, a sweep gas, such as steam or nitrogen, is injected into the reactor, either with the organic liquid feed in the reactor feed pipe (21) and the spray nozzles (22), or through a secondary feed line (not shown).

The plates are lifted from the plate bed (24) by the shelves (20). In this illustration, the reactor (25) is supported by two horizontal cylinders (26) and is heated externally with gas or naphtha burners (27). The reactor rotates inside a heating chamber, which is stationary (38). There are various options for the heating chamber. It could be a section of a hot stack, where the stack gas needs to be cooled before clean-up, for example. A seal (37) is shown around the rotating kiln and the stationary wall of the heating chamber. It is useful to keep the feed pipe in place with support rings (28), as illustrated on Figure 11. The gas and entrained coke leave the reactor through the gas exit pipe (29). Accumulated solid coke is scooped up by shovels (30), is dumped into a hopper (31), and is carried out of the reactor with the help of a screw conveyor (32) inside the solids exit pipe (33). There is a seal (34) between the rotating reactor and the product exit box (35). The product exit box is stationary. A first separation of solids and vapours occurs in the product exit box (35).

Figures 11 A and 1 IB are two cases of center ring supports for the feed line (39), shown when the reactor is cool. Figure 11C is the support rings in Figure 1 IB when the reactor is hot. Figure 11 A is for a smaller reactor radius with only one centre ring (40). Figure 1 IB is for a larger reactor radius, for which two centre rings (40) and (41) are required to avoid deforming the support legs (42). In Figures 1 IB and C there are two sets of support legs:

The first (42) hold the larger centre ring (41) in place. The second set of support legs hold the smaller centre ring (40) in place. The smaller centre ring supports the reactor feed pipe (39). The support legs (42) and (43) are attached to the reactor wall (45) and/or centre rings with brackets (44) that permit and/or allow the support beams to expand and rotate at their junction points with the reactor walls and rings.

Figure 12 shows a vertical cross section of a reactor in the slanted position, about 5° from the horizontal in this illustration. This reactor would be used for feedstocks that contain solids such as sand. The reactor actually has four shelves, but only two are shown here (20). The other two shelves would be on the section not shown. The feed enters the reactor in pipe (21), it is pushed along the feed line with a screw conveyor and is projected unto the hot plates (23) by nozzles, holes and/or slits (22). The plates (23) are rectangular and are about as long as the reactor section where they are installed. The plates are lifted from the plate bed (24) by the shelves (20). In this illustration, the reactor (25) is supported by two slanted cylinders (26) and is heated externally with gas or naphtha burners (27). The reactor rotates inside a heating chamber, which is stationary (38). A seal (37) is shown around the rotating kiln and the stationary wall of the heating chamber. The gas and entrained coke leave the reactor through the gas exit pipe (29). The solids that are too heavy to be entrained out of the reactor by the gas, slide long the reactor floor, through the screen (36), and are scooped up by the scoops (30). Accumulated solids are scooped up, along with residual coke, by shovels (30), are dumped into a hopper (31), and are carried out of the reactor with the help of a screw conveyor (32) inside the solids exit pipe (33). There is a seal (34) between the rotating reactor and the product exit box (35). The product exit box is stationary. A first separation of solids and vapours occurs in the product exit box (35).

Figure 13 shows two possible configurations for the screens (36) in Figures 12 and 14. Figure 13A is a screen made of wire mesh. Figure 13B is a screen made of a perforated disc. Both screens are tacked on to the reactor wall. Their outer circumferences are scalloped, allowing for different thermal expansions of the reactor walls and the screens with minimal stress on the reactor walls. Both configurations permit both the vapours and the solids to travel practically unimpeded from one end of the reactor to the other. The perforations are calculated so as to avoid movement of the plates from one section to the other. Also, the perforations must be too small for the ends of the plates to enter. The screens will be scraped clean by the plates, as the reactor turns.

Figure 14 is a vertical cross section of a reactor in the slanted position, about 5° from the horizontal is illustrated here.

This reactor would be used for feedstocks that contain solids such as sand.

The reactor actually has four shelves, but only two are shown here (20). The other two shelves would be on the section not shown. The feed enters the reactor in pipe (21), it is pushed along the feed line with a screw conveyor and is projected unto the hot plates (23) through the end of the pipe or slits in the pipe (22). The plates (23) are rectangular and are about as long as the reactor section where they are installed when the reactor is heated. The plates are lifted from the plate bed (24) by the shelves (20). In this illustration, the reactor (25) is supported by two slanted cylinders (26) and is heated externally with gas or naphtha burners (27). The reactor rotates inside a heating chamber, which is stationary (38). A seal (37) is shown around the rotating kiln and the stationary wall of the heating chamber. The gas and entrained coke leave the reactor through the gas exit pipe (29). The solids that are too heavy to be entrained out of the reactor by the gas, slide long the reactor floor, through the screens (36), and are scooped up by the scoops (30). Accumulated solids are scooped up, along with residual coke, by shovels (30), are dumped into a hopper (31), and are carried out of the reactor with the help of a screw conveyor (32) inside the solids exit pipe (33). There is a seal (34) between the rotating reactor and the product exit box (35).

The product exit box is stationary. A first separation of solids and vapours occurs in the product exit box (35).

Figure 16 shows a vertical cross section of a reactor made up of two cones joined at the base.

This shape of reactor allows the plates to slide back towards the entrance and scrape the walls, other plates and the shelves clean of coke and other deposited solids.

Figure 17 represents a vertical cross section of a reactor in the slanted position, about 5° from the horizontal is illustrated here. This reactor would be used for heavy oils feedstocks that may produce more coke or contain sand or contaminated soils.

Example 1 - treatment of feed material with high CCR

The feedstock is 20 tons per day of vacuum tower asphalt extender (VTAE), having a specific gravity of 0.95 and containing 6% wt. metals. The material is fed into the liquification vessel and brought to temperature of 300°C. No material exits through self-refluxing condenser at this stage.

The heated VTAE is pumped into the rotating drum, equipped with 12 sections delimited by punctured separators having four holes each, along with 5% wt. superheated steam. The shelves in the reactor consist of long rectangular shelves, similar to shelf 4 which can be viewed in Figure 41. The product is sprayed onto the plates. As the system turns the 10% wt. solids formed during pyrolysis reactions and/or fed into the reactor keep accumulating, as the transfer of the solids between the sections is not moving to the shovels fast enough. This is because of the polarized properties of the solid materials, which causes them to stick to surfaces. After a while, the sprays hit the accumulated solids and do not crack immediately. This increases the quantity of solids in the reactor and the system does not work properly. By eliminating the separators, and replacing the shelves with shelves consisting of a series of shelf Is which can be viewed in Figure 38, the 10% wt. solids are taken out through the use of the shovels, and the products obtained are 60% wt. diesel, 15% wt. heavy fuel, 4% wt. water, and 11% wt. gas and incondensable.

Example 2 -

The feedstock is a 40 ton mixture of recycled material obtained from MSW per day, such as plastics mixed with some other organic material. This feedstock is comprised of plastics mixed with dirt and cellulose, having a composition of about 72% wt. mixed plastics, 20% wt. cellulose, 4% wt. water and the balance being various other materials such as dirt and organics that could not be separated.

The mixture is shredded in an industrial shredding machine and then pulverized in a pulverizer machine to obtain particles having dimensions of an average of 3mm. The pulverized material is then put in the liquifier, where it is brought to a temperature of 260 degrees Celsius. The water and some gases from some of the cracking of some plastics and/or other material exits through the self-refluxing condenser in the liquifier. Approximately 8% wt. of the material is taken in that step, most of it being water and gas and naphtha.

The rest of the mixture is pumped into the rotating drum, equipped with 12 sections delimited by punctured separators having four holes each, along with 4% wt. superheated steam. The shelves in the reactor consist of long rectangular shelves, similar to shelf 4 which can be viewed in Figure 41. The product is sprayed onto the plates.

As the system turns the 6% wt. solids formed during pyrolysis reactions and/or fed into the reactor keep accumulating, as the transfer of the solids between the sections is not moving to the shovels fast enough. This is because of the polarized properties of the solid materials, which causes them to stick to surfaces. After a while, the sprays hit the accumulated solids and do not crack immediately. This increases the quantity of solids in the reactor and the system does not work properly.

By eliminating the separators, and replacing the shelves with shelves consisting of a series of shelf Is which can be viewed in Figure 38, the 6% wt. solids are taken out through the use of the shovels, and the products obtained are 51% wt. diesel, 20 % wt. heavy fuel, 4% wt. water, and 11% wt. gas and incondensable, the balance being what ever water and light products removed in the liquification vessel.

ADVANTAGES OF THE PROCESS OF THE INVENTION

This process allows producing liquid fuels even from mainly organic material, and/or even from feeding material having a initial composition resulting during pyrolysis in a significant high amount of coke and/or solids.

This advantageous result is possible due to (a) specific preparatory treatment(s), particularly in the case wherein the feeding material contains important amount of solid materials and/or an important water content. This advantageous result is also possible due to the specific internal configuration of rotating kilns and/or apparatus used for performing processes/pyrolysis.

This is a simple process that can treat a wide variety of waste oils and/or other organic material and make useful and environmentally friendly products.

This process is in energy equilibrium. When used lubricating oils are processed, the produced gas and naphtha are consumed on site, and there is little or no need to purchase fuel, or to use the more valuable wide range diesel or heavy oil products from the plant. There is also no naphtha to dispose of.

The sulphur and metals, released in the cracking reactions, are mostly attached to the coke when exiting the reactor. The coke is removed from the vapour oil stream as it leaves the reactor. Therefore the sulphur and metals are not present when the oil is condensed into liquid fuels. A rotating kiln under positive pressure is safer because there will be no oxygen ingress into the reactor, which, if left undetected, could result in an explosion. In the event of a leak, oily vapours would exit into the firebox and would bum in an environment designed to contain flames.

One of the safety features of this process is that there is no vessel containing large amounts of oil in this process.

Residence times are low.

In summary some of the advantages of the new thermal processing apparatus include at least one of the followings:

- a steady and controllable reaction temperature;

- a specified product slate of consistent quality;

- a protection of the reactor wall from stress and failure due to thermal shock or hot spots;

- preventing coke from depositing and sticking on the reactor walls and internals;

- longer run times, shorter shut-downs, less maintenance cost;

- safer operation;

- no by-products to dispose of in industrial landfills;

- less need for the purchase of chemicals and disposal of spent chemicals; - a steady and controllable reaction pressure, and

- minimizing of the thermal stress on the reactor walls and/or on the internals.

Advantages of the reactor operating under positive pressure:

- better control of pressure in the reactor;

- no air ingress into the reactor, combusting the flammable vapours within the reactor;

- less risk of an explosion;

- steadier flow of products out the reactor; and

- better control of cyclone operation.

Advantages of the use of a sweep gas, over the use of the new thermal apparatus alone:

- sweep gas injection stabilizes reactor operations. Both pressure and temperature are selected and kept in the range appropriate to a particular feedstock;

- the presence of sweep gas inside the reactor reduces the partial pressure of the organic reactor feed and/or the organic vapours, helping the vaporization of the lighter bio-oil and/or organic vapour components. This reduces the incidence of over-cracking, resulting in a more stable organic product slate;

- sweep gas helps in keeping the velocity of the vapours exiting the reactor, improving the

separation of the solids from the reactor products;

- sweep gas injection effectively reduces organic vapours’ residence time, thereby reducing the incidence of secondary reactions, and destabilization of the product gasoil and/or bio-oil; and

- sweep gas injection rates can compensate for variations in feedstock quantities.

Similarly, sweep gas injection allows the use of the same reactor to treat very different feedstocks from municipal waste to used lubricating oils to bunker. This, in turn, permits the treating of a wide variety of waste.

The injection of the sweep gas makes for safer reactor operations. In the event of a leak in the reactor or downstream equipment, the steam present acts as snuffing steam, reducing the risk of a fire from oil and/or bio-oil and/or combustible vapours above its auto-ignition temperature coming in contact with air. Nitrogen can also reduce the risk of a fire.

In the event of steam as sweep gas, injection of steam into the reactor can reduce or replace stripping steam injection in the product separation stage.

Sweep gas injected into the reactor feed line can change the flow patterns and prevent coking in the piping and plugging of either the feed line or feed nozzle. It reduces the viscosity of the organic liquid reactor feed, and contributes to the atomization of the organic liquid reactor feed droplets through the spray nozzles.

If introduced into the feed line at temperatures above that of the organic liquid feed into the reactor, it reduces the amount of heat that must be generated by the kiln.

Advantages of the process:

Organic material thermal cracking process has many advantages over other organic material cracking or reuse processes:

- it is flexible and permits the treating of a wide variety of organic material;

- the sulphur and metals do not enter into the finished oil and/or bio-oil products;

- each liquid droplet entering the kiln takes the energy necessary to crack, but do not reach a

temperature at which they will crack again;

- there is no liquid phase present in the kiln at any time during its operation, so the vapours

produced are not wet, and thus do not readily pick up contaminants; and

- the vapours produced from pyrolysis do not travel through a thick film of solid and/or liquid, and thus do not readily pick up contaminants before exiting the kiln;

- there are no open vessels causing a bad odour; and

- the process is relatively quick and there are no long residence times.

In the cases wherein composition of the feeding material is about constant, the composition of the mixture exiting the rotating kiln may be about constant and/or easily managed. Some embodiments of the invention may have only one of these advantages; some embodiments may several advantages and may have all of simultaneously.

The preliminary transformation of MSW in agglomerate allows preliminary transformation in remote area and efficient and efficient and economic transportation on the site wherein transformation plant is installed.

Although the present invention has been described with the aid of specific embodiments, it should be understood that several variations and modifications may be grafted onto the embodiments and that the present invention encompasses such modifications, usages or adaptations of the present invention that will become known or conventional within the field of activity to which the present invention pertains, and which may be applied to the essential elements mentioned above.
