PARTICULAR LIQUID SOLUTION SUITABLE TO COOL DOWN AND CATCH THE POLLUTANTS THAT ARE INSIDE THE EXHAUSTS OF DIESEL ENGINES
Document Type and Number:
WIPO Patent Application WO/2018/167559
Kind Code:
A1
Abstract:
The particular liquid solution formulated on an aqueous basis with a surfactants mix and various oxides performs the cooling down and the catching of the harmful substances present in nitrogen oxides NOx, sulfur compounds and particulate matters PM10 that are inside the exhausts of diesel engines. The particular liquid solution is constantly purified and regenerated by a specific electrolytic reactor and then recirculated.

CLAIMS

1. We claim a particular liquid solution at aqueous basis with the addition of a surfactants mix suitable to cool down and catch the pollutants that are inside the exhausts of diesel engines, which is composed by all the following components in the volumetric percentage hereinafter indicated:

- a distilled water H20 more than 90% in volume (best suggested percentage 93%)

- a surfactants mix which comprises: sodium dodecylbenzenesulfonate Ci8H2gNa03S; sodium alkyl sulfonate; sulfonated derivatives of benzimidazole; ethanolamine from Fatty Acids, where the volumetric percentage of surfactants mix is between 0,6% and 5, 4% (best suggested 3,8%)

- a potassium carbonate K2CO3 in volumetric percentage between 0,7% and 3,6% (best suggested 2,3%)

- a potassium permanganate KMn04 in volumetric percentage between 0,06% and 1,35% (best suggested 0,65%)

- a potassium hydroxide KOH in volumetric percentage between 0,07% and 1,25% (best suggested 0,25%)

2. We claim a particular liquid solution as claimed in claim 1 characterized by a surfactants mix in which its components have the percentages hereinafter indicated: between 45% and 85% (best suggested 60%) of sodium dodecylbenzenesulfonate Ci8H29Na03S; between 12% and 30% (best suggested 20%) of sodium alkyl sulfonate; between 8% and 25% (best suggested 15%) of sulfonated derivatives of benzimidazole; between 2% and 7% (best 5%) of ethanolamine from Fatty Acids

AMENDED CLAIMS

received by the International Bureau on 24 August 2018 (24.08.2018)

1. We claim a particular liquid solution at aqueous basis with the addition of a surfactants mix that blends with exhausts and simultaneously cools them down to a temperature between 35° and 55° and it is therefore suitable to cool down and catch the pollutants that are inside the exhausts of diesel engines, which is composed by all the following components in the volumetric percentage hereinafter indicated:

- a distilled water H2O more than 90% in volume (best suggested percentage 93%)

- a surfactants mix which comprises: sodium dodecylbenzenesulfonate Ci8H29Na03S; sodium alkyl sulfonate; sulfonated derivatives of benzimidazole; ethanolamine from Fatty Acids, where the volumetric percentage of surfactants mix is between 0,6% and 5, 4% (best suggested 3,8%)

- a potassium carbonate K2CO3 in volumetric percentage between 0,7% and 3,6% (best suggested 2,3%)

- a potassium permanganate KMn04 in volumetric percentage between 0,06% and 1,35% (best suggested 0,65%)

- a potassium hydroxide KOH in volumetric percentage between 0,07% and 1,25% (best suggested 0,25%)

2. We claim a particular liquid solution as claimed in claim 1 characterized by a surfactants mix in which its components have the percentages hereinafter indicated: between 45% and 85% (best suggested 60%) of sodium dodecylbenzenesulfonate Ci8H29Na03S; between 12% and 30% (best suggested 20%) of sodium alkyl sulfonate; between 8% and 25% (best suggested 15%) of sulfonated derivatives of benzimidazole; between 2% and 7% (best 5%) of ethanolamine from Fatty Acids

Description:
DESCRIPTION of the industrial invention bearing the title: "Particular liquid solution suitable to cool down and catch the pollutants that are inside the exhausts of diesel engines"

The particular liquid solution, subject of this invention, formulated according to the table shown in Fig. 1 allows the neutralization of all the harmful substances (NOx and S0 2 ) that are inside the exhausts of diesel engines. The particular liquid solution blends with exhausts and simultaneously cools them down to temperature in range between 35°C and 55°C, just little more than ambient temperature. These conditions facilitate the catching of particular matters PMio that are also inside the exhaust with the result that they are not dragged by exhausts stream. The optimum operating mode of cooling and mixing with exhausts requires a specific catalytic bed where the particular liquid solution performs its functions.

Being the particular liquid solution at aqueous basis (more than 90% by volume), it can operate at low temperature and be treated by means of electrolytic process for its purification and regeneration.

To facilitate the catching and then the dispersion of carbon clusters of various sizes as well as particular matters PMio, the particular liquid solution requires different types of efficient surfactants.

The presence in the particular liquid solution of potassium carbonate K2CO3 in conjunction with potassium hydroxide KOH allows the selective neutralization of the acidic compounds of NOx and SO2.

The presence of potassium permanganate KMn0 4 , a strongly oxidizing compound, facilitates the oxidation of nitric oxide NO to become nitrogen dioxide NO2, the latter being more easily neutralized by potassium hydroxide KOH. The composition of this particular liquid solution makes possible its purification and regeneration from harmful substances, process that takes place in an appropriate electrolytic reactor as the ions present in the solution allow the recombination of original composition, thus not requiring additions of solutes during the numerous operative cycles and keeping anyway its functional characteristics.

Fig. 1 displays the diagram related to the volumetric percentages, as range and as best suggested, of the different components of the particular liquid solution subject of this invention.

The best suggested composition is: 93% of distilled water, 3,8% of surfactants mix, 2,3% of potassium carbonate K2CO3, 0,65% of potassium permanganate KMn04, 0,25% of potassium hydroxide KOH.
