ORGANOSILICA MATERIALS, METHODS

OF MAKING, AND USES THEREOF

FIELD OF THE INVENTION

[0001] The present invention relates to organosilica materials, methods of making, and uses thereof.

BACKGROUND OF THE INVENTION

[0002] Porous inorganic solids have found great utility as catalysts and separation media for industrial application. In particular, mesoporous materials, such as silicas and aluminas, having a periodic arrangement of mesopores are attractive materials for use in catalysis processes due to their uniform and tunable pores, high surface areas and large pore volumes. Such mesoporous materials are known to have large specific surface areas (e.g., 1000 m ² /g) and large pore volumes (e.g., 1 cm ³ /g). For these reasons, such mesoporous materials enable reactive catalysts.

[0003] Mesoporous organosilica materials are conventionally formed by the self- assembly of the silsequioxane precursor in the presence of a structure directing agent, a porogen and/or a framework element. The precursor is hydrolysable and condenses around the structure directing agent. These materials have been referred to as Periodic Mesoporous Organosilicates (PMOs), due to the presence of periodic arrays of parallel aligned mesoscale channels. For example, Landskron, K., et al. [Science, 302:266-269 (2003)] report the self-assembly of l, l,3,3,5,5-hexaethoxy-l,3,5-trisilacyclohexane [(EtO) ₂ SiCH ₂ ]3 in the presence of a base and the structure directing agent,

cetyltrimethylammonium bromide, to form PMOs that are bridged organosilicas with a periodic mesoporous framework, which consist of S1O ₃ R or Si0 ₂ R ₂ building blocks, where R is a bridging organic group. In PMOs, the organic groups can be

homogenously distributed in the pore walls. U.S. Patent Application Publication No. 2012/0059181 reports the preparation of a crystalline hybrid organic-inorganic silicate formed from l,l,3,3,5,5-hexaethoxy-l,3,5-trisilacyclohexane in the presence of NaA10 ₂ and base. U.S. Patent Application Publication No. 2007/003492 reports preparation of a composition formed from 1, 1, 3,3,5, 5-hexaethoxy-l, 3,5- trisilacyclohexane in the presence of propylene glycol monomethyl ether. [0004] However, the use of a structure directing agent, such as a surfactant, in the preparation of an organosilica material, requires a complicated, energy intensive process to eliminate the structure directing agent at the end of the preparation process. For example, calcining may be required as well as wastewater disposal steps and associated costs to dispose of the structure directing agent. This limits the ability to scale-up the process for industrial applications. Additionally, because of the relative expense of complex organic-inorganic hybrid siliceous (monomer) materials, it would be beneficial to maintain as many of the structure and properties as possible of a material made from relatively expensive siliceous reactants, while lowering the cost by co-incorporating less expensive reactants, such as silica.

[0005] Therefore, there is a need for improved catalysts/adsorbents and/or processes for making catalysts using organosilica materials that can be prepared at as low a cost as possible by methods that can be practiced in the absence of a structure directing agent, porogen, or surfactant.

SUMMARY OF THE INVENTION

[0006] In one aspect, embodiments of the invention provide a method of making an organosilica material. The method can advantageously include a step of providing an aqueous mixture that contains essentially no structure directing agent and/or porogen. To the aqueous mixture can be added at least one compound of: (i) Formula (I),

[Z ¹⁵ Z ¹⁶ SiCH ₂ ] ₃ , wherein each Z ¹⁵ can be a C1-C4 alkoxy group and each Z can be a C ₁ -C ₄ alkoxy group or a C ₁ -C ₄ alkyl group; and/or (ii) a cyclic polyurea monomer of formula (IV),

wherein each R ¹ independently is a X ⁵ OX ⁶ X ⁷ SiX ⁸ group, wherein each X ⁵ represents a C ₁ -C ₄ alkyl group; X ⁶ and X ⁷ each independently represent a C ₁ -C ₄ alkyl group or a C ₁ -C ₄ alkoxy group; and each X represents a Ci-C ₈ alkylene group bonded to a nitrogen atom of the cyclic polyurea; and (iii) an additional comonomer comprising a source of silica that is reactive to polymerize with the at least one compound of Formula (I) and/or Formula (IV). The thus-formed solution can then be aged to produce a pre-product, which can be dried to obtain the organosilica material, which is a polymer comprising at least one independent monomer of Formula (I) and/or Formula (IV) as described herein that are linked to the silica through at least one silyl ether bond.

[0007] In another aspect, organosilica materials made according to the methods of the invention are provided. Additionally or alternatively, an organosilica material can include a polymer of at least one independent monomer comprising: (i) a monomer of formula (I), [Z ¹⁵ Z ¹⁶ SiCH ₂ ]3, wherein each Z ¹⁵ can individually be a C ₁ -C ₄ alkyl group, a C ₁ -C ₄ alkoxy group, a hydroxyl group, or an oxygen atom bonded to a silicon atom of another monomer, and each Z ¹⁶ can individually be a C ₁ -C ₄ alkyl group, a C ₁ -C ₄ alkoxy group, a hydroxyl group, or an oxygen atom bonded to a silicon atom of another monomer; and/or (ii) a cyclic polyurea monomer of formula (IV),

wherein each R ¹ independently is a X ⁵ OX ⁶ X ⁷ SiX ⁸ group, wherein each X ⁵ represents a hydrogen atom, a C ₁ -C ₄ alkyl group, or a bond to a silicon atom of another monomer unit; X ⁶ and X ⁷ each independently represent a hydroxyl group, a C ₁ -C ₄ alkyl group, a

C. Source of Reactive Silica

[0073] In various embodiments, the organosilica material further comprises an additional monomer in combination with independent units of Formula (I) and/or Formula (IV), which is a source of silica that is reactive to polymerize therewith. In order to participate in (condensation) polymerization reactions with the other monomers, the silica should typically have (or be treated to have) some hydroxyl group functionality. Examples of silica sources can include, but are not limited to, colloidal silica (such as commercially under the tradename LUDOX™ from W.R. Grace & Co. of Columbia, MD, USA) and/or other particulate silicas having a sufficiently small particle size. Particle sizes of silicas can be approximated as the diameter of spherical (or near-spherical) particles. If particles are substantially non-spherical, then their particle size herein can be a simple average of the sizes of the three dimensions (whether length/width/height for polygonal and/or elliptical particles, diameter/height for circular cylindrical particles, or other appropriate dimensions for some other odd shape). Additionally or alternatively, silica sources can include pre-polymerized/pre- oligomerized versions of particulate silicas, which can be linked to each other via condensation through the presence of a hydroxyl group attached to one or more, preferably two or more, silicon atoms thereof.

[0074] Exemplary average particle sizes for particulate/colloidal silica sources can be up to about 400 nm, e.g., up to about 250 nm, up to about 150 nm, up to about 120 nm, up to about 100 nm, up to about 80 nm, up to about 60 nm, up to about 50 nm, up to about 40 nm, up to about 30 nm, up to about 25 nm, up to about 20 nm, up to about 15 nm, or up to about 10 nm. In particular, the average particle size can be up to about 150 nm, up to about 100 nm, up to about 50 nm, up to about 30 nm, or up to about 25 nm. While minimum particle size is not believed to be critical in most embodiments, in some embodiments the practical minimum average particle size can be about 5 nm or about 3nm. In particular, the average particle size can be from about 3 nm to about 150 nm, about 3 nm to about 100 nm, about 3 nm to about 50 nm, or about 5 nm to about 30 nm. Additionally or alternatively, the silica sources can have particle size distributions such that the d95 (i.e., the diameter of which about 95% of particles in the distribution meet or exceed) can be up to about 500 nm, e.g., up to about 250 nm, up to about 200 nm, up to about 175 nm, up to about 150 nm, up to about 125 nm, up to about 100 nm, up to about 80 nm, up to about 60 nm, up to about 50 nm, up to about 40 nm, up to about 30 nm, up to about 25 nm, up to about 20 nm, up to about 15 nm, or up to about 10 nm; optionally, in such embodiments, the d95 of the particle size distribution can be at least about 3 nm, e.g., at least about 5 nm, at least about 10 nm, at least about 15 nm, at least about 20 nm, or at least about 25 nm. In particular, the d95 of the particle size distribution can be from about 3 nm to about 200 nm, from about 5 nm to about 100 nm, from about 5 nm to about 60 nm, or from about 10 nm to about 50 nm.

[0075] If treatment of the silica source is necessary or desitred, to attain adequate or additional hydroxyl group functionality for polymerization reaction, it can typically be accomplished under basic pH conditions. Such treatment may affect aspects of the particle size distribution of the silica source, including the d95 and/or average particle sizes, in which case the treated values are to be used. Furthermore, silica sources according to this invention are typically not treated to have so many hydroxyl group functionalities that the silica sources react to form predominantly (i.e., more than 50 mol%) Si(OH) ₄ .

Catalyst Metal

[00201] The organosilica materials may further be treated to comprise at least one catalyst metal, particularly in embodiments where the end use application is a catalytic one. The at least one catalyst metal may be deposited onto, and advantageously incorporated within the pores of, the organosilica material. Exemplary catalyst metals can include, but are not limited to, a Group 6 metal, a Group 8 metal, a Group 9 metal, a Group 10 metal, or a combination thereof. Exemplary Group 6 metals can include, but are not limited to, chromium, molybdenum, and/or tungsten, particularly including molybdenum and/or tungsten. Exemplary Group 8 metals can include, but are not limited to, iron, ruthenium, and/or osmium. Exemplary Group 9 metals can include, but are not limited to, cobalt, rhodium, and/or iridium, particularly including cobalt. Exemplary Group 10 metals can include, but are not limited to, nickel, palladium and/or platinum.

[00202] In a particular embodiment, the catalyst metal may be a noble metal selected from the group consisting of a Group 8 metal, a Group 9 metal, a Group 10 metal and a combination thereof. Additionally or alternatively, the at least one catalyst metal may be selected from the group consisting of platinum (Pt), palladium (Pd), iridium (Ir), rhodium (Rh), rehenium (Re), ruthenium (Ru), osmium (Os) or a combination thereof, particularly, platinum (Pt), palladium (Pd), and a mixture thereof.

[00203] The catalyst metal may be present in an amount of at least about 0.01 wt%, e.g., at least about 0.05 wt%, at least about 0.1 wt%, at least about 0.2 wt%, at least about 0.4 wt%, at least about 0.5 wt%, at least about 0.6 wt%, at least about 0.8 wt%, at least about 1.0 wt%, at least about 1.2 wt%, at least about 1.4 wt%, at least about 1.5 wt%, at least about 1.6 wt%, at least about 1.8 wt%, at least about 2.0 wt%, at least about 2.2 wt%, at least about 2.4 wt%, at least about 2.6 wt%, at least about 2.8 wt%, at least about 3.0 wt%, at least about 3.5 wt%, or at least about 4.0 wt%.

All catalyst metal weight percents are on support. By "on support" it is meant that the percents are based on the weight of the support, i.e., organosilica material. For example, if the organosilica material were to weigh -100 grams, then -20 wt% catalyst metal would mean that -20 grams of the catalyst metal(s) was(were) added onto the organosilica material.

In particular, when the catalyst metal is a noble metal, it may be present in an amount of about 0.01 wt% to about 4.0 wt%, about 0.05 wt% to about 3.5 wt%, about 0.1 wt% to about 2.0 wt%, or about 0.1 wt% to about 1.4 wt%.

[00205] In another particular embodiment, the catalyst metal may include at least one Group 6 metal and at least one non-noble metal from Groups 8-10. Additionally or alternatively, the catalyst metal may include at least one of chromium, molybdenum, and tungsten (particularly including molybdenum and/or tungsten), as well as at least one of iron, cobalt, and nickel (particularly including cobalt and/or nickel).

N. Binder

[00207] In various aspects, the organosilica materials described herein may be further combined with binder. Suitable binders can include, but need not be limited to, active and inactive materials, synthetic or naturally occurring zeolites, as well as inorganic materials such as clays and/or oxides such as silica, alumina, zirconia, titania, silica-alumina, cerium oxide, magnesium oxide, or combinations thereof. In particular, the further binder may be selected from the group consisting of active and inactive materials, inorganic materials, clays, alumina, silica, silica-alumina, titania, zirconia, or a combination thereof. Particularly, the further binder may be silica-alumina, alumina and/or zirconia, particularly alumina. Silica-alumina may be either naturally occurring or in the form of gelatinous precipitates or gels including mixtures of silica and metal oxides. It should be noted it is recognized herein that the use of a material in conjunction with a zeolite binder material, i.e., combined therewith or present during its synthesis, which itself is catalytically active may change the conversion and/or selectivity of the finished catalyst. It is also recognized herein that inactive materials can suitably serve as diluents to control the amount of conversion if the present invention is employed in alkylation processes so that alkylation products can be obtained economically and orderly without employing other means for controlling the rate of reaction. These inactive materials may be incorporated into naturally occurring clays, e.g., bentonite and kaolin, to improve the crush strength of the catalyst under commercial operating conditions and function as binders or matrices for the catalyst.

O. Additional Metals

[00208] In some embodiments, the organosilica material can further be combined with cationic metal sites incorporated into the network structure. Such cationic metal sites may be incorporated by any convenient method, such as impregnation or complexation to the surface, through an organic precursor, or by some other method. This organometallic material may be employed in a number of hydrocarbon separations conducted in petroleum refining or petrochemicals production. Examples of such compounds to be desirably separated from petrochemicals/fuels can include olefins, paraffins, aromatics, and the like.

[00209] Additionally or alternatively, the organosilica material can have deposited thereon/therein a surface metal within the pores of the organosilica material. The surface metal can be selected from a Group 1 element, a Group 2 element, a Group 13 element, and a combination thereof. When a Group 1 element is present, it can preferably comprise or be sodium and/or potassium. When a Group 2 element is present, it can include, but may not be limited to, magnesium and/or calcium. When a Group 13 element is present, it can include, but may not be limited to, boron and/or aluminum.

[00210] One or more of the Group 1, 2, 6, 8-10 and/or 13 elements may be present on an exterior and/or interior surface of the organosilica material support. For example, one or more of the Group 1, 2 and/or 13 elements may be present in a first layer on the organosilica material and one or more of the Group 6, 8, 9 and/or 10 elements may be present in a second layer, e.g., at least partially atop the Group 1, 2 and/or 13 elements. Additionally or alternatively, only one or more Group 6, 8, 9 and/or 10 elements may present on an exterior and/or interior surface of the organosilica material. The surface metal(s) can be incorporated into/onto the organosilica material by any convenient method, such as by impregnation, deposition, grafting, co-condensation, by ion exchange, and/or the like. In particular, a Group 13 metal, such as, but not limited to, aluminum may be grafted onto a surface of the organosilica material support.

Additionally or alternatively, a Group 4 metal, such as, but not limited to, titanium, zirconium and hafnium, may be grafted onto a surface of the organosilica material support.

III. Methods of Making Catalysts

[00211] In another embodiment, methods of producing the organosilica material described herein are provided. The methods can advantageously comprise:

(a) providing an aqueous mixture that contains essentially no structure directing agent and/or porogen;

(b) adding into the aqueous mixture to form a solution at least one compound of: (i) Formula (I), [Z ¹⁵ Z ¹⁶ SiCH ₂ ] ₃ , wherein each Z ¹⁵ can be a C ₁ -C4 alkoxy group and each Z ¹⁶ can be a Ci-C ₄ alkoxy group or a Ci-C ₄ alkyl group; and/or (ii) a cyclic polyurea monomer of formula (IV),

wherein each R ¹ independently is a X ⁵ OX ⁶ X ⁷ SiX ⁸ group, wherein each X ⁵ represents a C ₁ -C ₄ alkyl group; X ⁶ and X ⁷ each independently represent a C ₁ -C ₄ alkyl group or a C ₁ -C ₄ alkoxy group; and each X ⁸ represents a Ci-C ₈ alkylene group bonded to a nitrogen atom of the cyclic polyurea; and (iii) an additional comonomer comprising a source of silica that is reactive to polymerize with the at least one compound of Formula (I) and/or Formula (IV);

(c) aging the solution to produce a pre-product; and

(d) drying the pre-product to obtain an organosilica material which is a polymer comprising at least one independent monomer of Formula (I) and/or Formula (IV) as described herein that are linked to the silica (and/or to each other) through at least one (and preferably at least two) silyl ether bonds.

[00212] Additionally or alternatively, at least a portion of the compounds of Formula (I) and/or the cyclic polyuria monomer of formula (IV) can be added in step (b) as at least partially hydroxylated and/or as at least partially polymerized/oligomerized, such that each Z ¹⁵ can more broadly represent a hydroxyl group, a C ₁ -C ₄ alkoxy group or an oxygen atom bonded to a silicon atom of another siloxane and each Z ¹⁶ can more broadly represent a hydroxyl group, a C ₁ -C ₄ alkoxy group, a C ₁ -C ₄ alkyl group, or an oxygen atom bonded to a silicon atom of another siloxane and/or such that each X ⁵ can more broadly represent a hydrogen atom, a C ₁ -C ₄ alkyl group, or a bond to a silicon atom of another monomer unit; X ⁶ and X ⁷ can each independently more broadly represent a hydroxyl group, a C ₁ -C ₄ alkyl group, a C ₁ -C ₄ alkoxy group, or an oxygen atom bonded to a silicon atom of another monomer unit; and each X ⁸ can more broadly represent a Ci-C ₈ alkylene group bonded to a nitrogen atom of the cyclic polyurea. In other words, an unaged pre-product can be added in step (b), in addition to or as an alternative to the monomeric compound(s) of Formula (I) and/or Formula (IV). [00213] Further additionally or alternatively, at least a portion of the silica (e.g., reactive with itself and the other compound(s) of Formula (I) and/or Formula (IV) via condensation through the presence of a hydroxyl group attached to one or more, preferably two or more, silicon atoms) can be added to step (b) as at least partially hydroxylated and/or as at least partially polymerized/oligomerized (i.e., as an unaged pre-product, in addition to or as an alternative to the particulate silica source).

A. Aqueous Mixture

[00214] The catalysts described herein may be made using essentially no structure directing agent or porogen. Thus, the aqueous mixture can contain essentially no added structure directing agent and/or no added porogen.

[00215] As used herein, "no added structure directing agent," and "no added porogen" means either (i) there is no component present in the synthesis of the organosilica material that aids in and/or guides the polymerization and/or

polycondensing and/or organization of the building blocks that form the framework of the organosilica material; or (ii) such component is present in the synthesis of the organosilica material in a minor, or a non-substantial, or a negligible amount such that the component cannot be said to aid in and/or guide the polymerization and/or polycondensing and/or organization of the building blocks that form the framework of the organosilica material. Further, "no added structure directing agent" is synonymous with "no added template" and "no added templating agent."

1. Structure Directing Agent

[00216] Examples of a structure directing agent can include, but are not limited to, non-ionic surfactants, ionic surfactants, cationic surfactants, silicon surfactants, amphoteric surfactants, polyalkylene oxide surfactants, fluorosurfactants, colloidal crystals, polymers, hyper branched molecules, star-shaped molecules, macromolecules, dendrimers, and combinations thereof. Additionally or alternatively, the surface directing agent can comprise or be a poloxamer, a triblock polymer, a

tetraalkylammonium salt, a nonionic polyoxyethylene alkyl, a Gemini surfactant, or a mixture thereof. Examples of a tetraalkylammonium salt can include, but are not limited to, cetyltrimethylammonium halides, such as cetyltrimethylammonium chloride (CTAC), cetyltrimethylammonium bromide (CTAB), and

octadecyltrimethylammonium chloride. Other exemplary surface directing agents can additionally or alternatively include hexadecyltrimethylammonium chloride and/or cetylpyridinium bromide.

[00217] Poloxamers are block copolymers of ethylene oxide and propylene oxide, more particularly nonionic triblock copolymers composed of a central hydrophobic chain of polyoxypropylene (poly(propylene oxide)) flanked by two hydrophilic chains of polyoxyethylene (poly(ethylene oxide)). Specifically, the term "poloxamer" refers to a polymer having the formula HO(C ₂ H4))a(C ₃ H ₆ 0) (C ₂ H ₄ 0) _a H in which "a" and "b" denote the number of polyoxyethylene and polyoxypropylene units, respectively.

Poloxamers are also known by the trade name Pluronic®, for example Pluronic® 123 and Pluronic® F 127. An additional triblock polymer is B50-6600.

[00218] Nonionic polyoxyethylene alkyl ethers are known by the trade name Brij®, for example Brij® 56, Brij® 58, Brij® 76, Brij ® 78. Gemini surfactants are compounds having at least two hydrophobic groups and at least one or optionally two hydrophilic groups per molecule have been introduced.

2. Porogen

[00219] A porogen material is capable of forming domains, discrete regions, voids and/or pores in the organosilica material. An example of a porogen is a block copolymer (e.g., a di -block polymer). As used herein, porogen does not include water. Examples of polymer porogens can include, but are not limited to, polyvinyl aromatics, such as polystyrenes, polyvinylpyridines, hydrogenated polyvinyl aromatics, polyacrylonitriles, polyalkylene oxides, such as polyethylene oxides and polypropylene oxides, polyethylenes, polylactic acids, polysiloxanes, polycaprolactones,

polycaprolactams, polyurethanes, polymethacrylates, such as polymethylmethacrylate or polymethacrylic acid, polyacrylates, such as polymethylacrylate and polyacrylic acid, polydienes such as polybutadienes and polyisoprenes, polyvinyl chlorides, polyacetals, and amine-capped alkylene oxides, as well as combinations thereof.

[00220] Additionally or alternatively, porogens can be thermoplastic homopolymers and random (as opposed to block) copolymers. As used herein, "homopolymer" means compounds comprising repeating units from a single monomer. Suitable thermoplastic materials can include, but are not limited to, homopolymers or copolymers of polystyrenes, polyacrylates, polymethacrylates, polybutadienes, polyisoprenes, polyphenylene oxides, polypropylene oxides, polyethylene oxides, poly (dimethyl siloxanes), polytetrahydrofurans, polyethylenes,

polycyclohexylethylenes, polyethyloxazolines, polyvinylpyridines, polycaprolactones, polylactic acids, copolymers of these materials and mixtures of these materials.

Examples of polystyrene include, but are not limited to anionic polymerized

polystyrene, syndiotactic polystyrene, unsubstituted and substituted polystyrenes (for example, poly(a-methyl styrene)). The thermoplastic materials may be linear, branched, hyperbranched, dendritic, or star like in nature.

[00221] Additionally or alternatively, the porogen can be a solvent. Examples of solvents can include, but are not limited to, ketones (e.g., cyclohexanone,

cyclopentanone, 2-heptanone, cycloheptanone, cyclooctanone,

cyclohexylpyrrolidinone, methyl isobutyl ketone, methyl ethyl ketone, acetone), carbonate compounds (e.g., ethylene carbonate, propylene carbonate), heterocyclic compounds (e.g., 3-methyl-2-oxazolidinone, dirnelhylirnidazolidinone, N- methylpyiTolidone, pyridine), cyclic ethers (e.g., dioxane, tetrahydrofuran), chain ethers (e.g., diethyl ether, ethylene glycol dimethyl ether, propylene glycol dimethyl ether, tetraethylene glycol dimethyl ether, polyethylene glycol dimethyl ether, ethylene glycol monomethyl ether, ethylene glycol monoethyl ether, propylene glycol monomethyl ether (PGME), triethylene glycol monobutyl ether, propylene glycol monopropyl ether, triethylene glycol monomethyl ether, diethylene glycol ethyl ether, diethylene glycol methyl ether, dipropylene glycol methyl ether, dipropylene glycol dimethyl ether, propylene glycol phenyl ether, tripropylene glycol methyl ether), alcohols (e.g., methanol, ethanol), polyhydric alcohols (e.g., ethylene glycol, propylene glycol, polyethylene glycol, polypropylene glycol, glycerin, dipropylene glycol), nitrile compounds (e.g., acetonitrile, glutarodinitrile, methoxyacetonitrile, propionitrile, benzonitrile), esters (e.g., ethyl acetate, butyl acetate, methyl lactate, ethyl lactate, methyl methoxypropionate, ethyl ethoxy propionate, methyl pyruvate, ethyl pyruvate, propyl pyruvate, 2-methoxyethyl acetate, ethylene glycol monoethyl ether acetate, propylene glycol monomethyl ether acetate (PGMEA), butyrolactone, phosphoric acid ester, phosphonic acid ester), aprotic polar substances (e.g., dimethyl sulfoxide, sulfolane, dimethylformamide, dimethylacetamide), nonpolar solvents (e.g., toluene, xylene, mesitylene), chlorine-based solvents (e.g., methylene di chloride, ethylene dichloride), benzene, dichlorobenzene, naphthalene, diphenyl ether, diisopropylbenzene, triethylamine, methyl benzoate, ethyl benzoate, butyl benzoate, monomethyl ether acetate hydroxy ethers such as dibenzylethers, diglyme, triglyme, and mixtures thereof.

[00242] In various aspects, adjusting the aging time and/or aging temperature of the solution formed in the methods described herein can affect the total surface area, microporous surface area, pore volume, pore radius and pore diameter of the organosilica material made. Thus, the porosity of the organosilica material may be adjusted by adjusting aging time and/or temperature.

[00243] For example, when the solution is aged for about 1 hour to about 7 hours (e.g., 1, 2, 3, 4, 5, 6 hours) at a temperature of about 80°C to about 100°C (e.g., 80°C, 85°C, 90°C, 95°C, etc.), the organosilica material may have one or more of the following:

(i) a total surface area of about 200 m ² /g to about 1400 m ² /g, particularly about 400 m ² /g to about 1300 m ² /g, and particularly about 400 m ² /g to about 1200 m ² /g;

(ii) a microporous surface area of about 200 m ² /g to about 600 m ² /g,

particularly about 200 m ² /g to about 500 m ² /g;

(iii) a pore volume of about 0.2 cm ³ /g to about 1.0 cm ³ /g, particularly about 0.2 cm ³ /g to about 0.8 cm ³ /g; and (iv) an average pore radius of about 0.5 nm to about 2.0 nm, particularly about 0.5 nm to about 2.0 nm, and particularly about 1.0 nm to about 1.5 nm.

[00244] Additionally or alternatively, when the solution is aged for greater than about 7 hours to about 150 hours (e.g., 23, 48, 72, 144 hours) at a temperature of about 80°C to about 100°C (e.g., 80°C, 85°C, 90°C, 95°C, etc.), the organosihca material may have one or more of the following:

(i) a total surface area of about 600 m ² /g to about 1400 m ² /g, particularly about 800 m ² /g to about 1400 m ² /g, and particularly about 800 m ² /g to about 1200 m ² /g;

(ii) substantially no microporous surface area;

(iii) a pore volume of about 0.8 cm ³ /g to about 1.4 cm ³ /g, particularly about 0.9 cm ³ /g to about 1.4 cm ³ /g; and

(iv) an average pore radius of about 1.0 nm to about 4.0 nm, particularly about 1.0 nm to about 4.0 nm.

[00245] Additionally or alternatively, when the solution is aged for about 1 hour to about 7 hours (e.g., 1, 2, 3, 4, 5, 6 hours) at a temperature of about 1 10°C to about 130°C (e.g., 1 10°C, 1 15°C, 120°C, 125°C, etc.), the organosihca material may have one or more of the following:

(i) a pore volume of about 1.0 cm ³ /g to about 1.8 cm ³ /g, particularly about 1.2 cm ³ /g to about 1.8 cm ³ /g, particularly about 1.4 cm ³ /g to about 1.7 cm ³ /g; and

(ii) an average pore diameter of about 2.0 nm to about 8.0 nm, particularly 4.0 nm to about 6.0 nm.

[00246] Additionally or alternatively, when the solution is aged for greater than about 7 hours to about 150 hours (e.g., 23, 48, 72, 144 hours) at a temperature of aboutl l0°C to about 130°C (e.g., 1 10°C, 1 15°C, 120°C, 125°C, etc.), the organosihca material may have one or more of the following:

(i) a pore volume of about 1.0 cm ³ /g to about 1.8 cm ³ /g, particularly about 1.2 cm ³ /g to about 1.8 cm ³ /g; and (ii) an average pore diameter of about 8.0 nm to about 16.0 nm, particularly about 10.0 nm to about 16.0 nm, particularly about 10.0 nm to about 14.0 nm.

[00247] Thus, at shorter aging times (e.g., 7, 6, 5, 4 hours, etc.) the surface area of an organosilica material made is microporous and mesoporous, but as aging time increase, the surface area transitions to primarily mesoporous. Further, as aging time increases, pore volume, average pore radius and average pore diameter increases. Increasing aging temperature along with aging time, accelerates the above-described surface area transition and increase in pore volume, average pore radius and average pore diameter.

[00251] In a particular embodiment, the pre-product (e.g., a gel) formed in the method can be dried at temperature from about 70°C to about 200°C.

[00252] Additionally or alternatively, the pre-product (e.g., a gel) formed in the method can be dried in a N ₂ and/or air atmosphere.

Additionally or alternatively, calcining can be performed at a temperature of about 300°C to about 650°C, about 300°C to about 600°C, about 300°C to about 550°C, about 300°C to about 400°C, about 300°C to about 450°C, about 300°C to about 400°C, about 300°C to about 350°C, about 350°C to about 650°C, about 350°C to about 600°C, about 350°C to about 550°C, about 350°C to about 400°C, about 350°C to about 450°C, about 350°C to about 400°C, about 400°C to about 650°C, about 400°C to about 600°C, about 400°C to about 550°C, about 400°C to about 500°C, about 400°C to about 450°C, about 450°C to about 650°C, about 450°C to about 600°C, about 450°C to about 550°C, about 450°C to about 500°C, about 500°C to about 650°C, about 500°C to about 600°C, about 500°C to about 550°C, about 550°C to about 650°C, about 550°C to about 600°C or about 600°C to about 650°C.

[00254] In some embodiments, the method can further comprise incorporating a catalyst metal within the pores of the organosilica material. Exemplary catalyst metals can include, but are not limited to, a Group 6 element, a Group 8 element, a Group 9 element, a Group 10 element or a combination thereof. Exemplary Group 6 elements can include, but are not limited to, chromium, molybdenum, and/or tungsten, particularly including molybdenum and/or tungsten. Exemplary Group 8 elements can include, but are not limited to, iron, ruthenium, and/or osmium. Exemplary Group 9 elements can include, but are not limited to, cobalt, rhodium, and/or iridium, particularly including cobalt. Exemplary Group 10 elements can include, but are not limited to, nickel, palladium and/or platinum.

[00255] The catalyst metal can be incorporated into the organosilica material by any convenient method, such as by impregnation, by ion exchange, or by complexation to surface sites. The catalyst metal so incorporated may be employed to promote any one of a number of catalytic tranformations commonly conducted in petroleum refining or petrochemicals production. Examples of such catalytic processes can include, but are not limited to, hydrogenation, dehydrogenation, aromatization, aromatic saturation, hydrodesulfurization, olefin oligomerization, polymerization, hydrodenitrogenation, hydrocracking, naphtha reforming, paraffin isomerization, aromatic transalkylation, saturation of double/triple bonds, and the like, as well as combinations thereof.

[00256] Thus, in another embodiment, a catalyst material comprising the

organosilica material described herein is provided. The catalyst material may optionally comprise a binder or be self-bound. Suitable binders, include but are not limited to active and inactive materials, synthetic or naturally occurring zeolites, as well as inorganic materials such as clays and/or oxides such as silica, alumina, zirconia, titania, silica-alumina, cerium oxide, magnesium oxide, or combinations thereof. In particular, the binder may be silica-alumina, alumina and/or a zeolite, particularly alumina. Silica-alumina may be either naturally occurring or in the form of gelatinous precipitates or gels including mixtures of silica and metal oxides. It should be noted it is recognized herein that the use of a material in conjunction with a zeolite binder material, i.e., combined therewith or present during its synthesis, which itself is catalytically active may change the conversion and/or selectivity of the finished catalyst. It is also recognized herein that inactive materials can suitably serve as diluents to control the amount of conversion if the present invention is employed in alkylation processes so that alkylation products can be obtained economically and orderly without employing other means for controlling the rate of reaction. These inactive materials may be incorporated into naturally occurring clays, e.g., bentonite and kaolin, to improve the crush strength of the catalyst under commercial operating conditions and function as binders or matrices for the catalyst. The catalysts described herein typically can comprise, in a composited form, a ratio of support material to binder material of about 100 parts support material to about zero parts binder material; about 99 parts support material to about 1 parts binder material; about 95 parts support material to about 5 parts binder material. Additionally or alternatively, the catalysts described herein typically can comprise, in a composited form, a ratio of support material to binder material ranging from about 90 parts support material to about 10 parts binder material to about 10 parts support material to about 90 parts binder material; about 85 parts support material to about 15 parts binder material to about 15 parts support material to about 85 parts binder material; about 80 parts support material to 20 parts binder material to 20 parts support material to 80 parts binder material, all ratios being by weight, typically from 80:20 to 50:50 support material :binder material, preferably from 65:35 to 35:65. Compositing may be done by conventional means including mulling the materials together followed by extrusion of pelletizing into the desired finished catalyst particles.

[00257] In some embodiments, the method can further comprise incorporating cationic metal sites into the network structure by any convenient method, such as impregnation or complexation to the surface, through an organic precursor, or by some other method. This organometallic material may be employed in a number of hydrocarbon separations conducted in petroleum refining or petrochemicals production. Examples of such compounds to be desirably separated from petrochemicals/fuels can include olefins, paraffins, aromatics, and the like.

[00258] Additionally or alternatively, the method can further comprise incorporating a surface metal within the pores of the organosilica material. The surface metal can be selected from a Group 1 element, a Group 2 element, a Group 13 element, and a combination thereof. When a Group 1 element is present, it can preferably comprise or be sodium and/or potassium. When a Group 2 element is present, it can include, but may not be limited to, magnesium and/or calcium. When a Group 13 element is present, it can include, but may not be limited to, boron and/or aluminum.

[00259] One or more of the Group 1, 2, 6, 8-10 and/or 13 elements may be present on an exterior and/or interior surface of the organosilica material. For example, one or more of the Group 1, 2 and/or 13 elements may be present in a first layer on the organosilica material and one or more of the Group 6, 8, 9 and/or 10 elements may be present in a second layer, e.g., at least partially atop the Group 1, 2 and/or 13 elements. Additionally or alternatively, only one or more Group 6, 8, 9 and/or 10 elements may present on an exterior and/or interior surface of the organosilica material. The surface metal(s) can be incorporated into/onto the organosilica material by any convenient method, such as by impregnation, deposition, grafting, co-condensation, by ion exchange, and/or the like.

IV. Uses of the Organosilica Materials

[00260] The organosilica materials described herein find uses in several areas.

[00261] In certain embodiments, the organosilica material described herein can be used as adsorbents or support matrices for separation and/or catalysis processes.

A. Gas Separation Processes

[00262] In some cases, the organosilica materials can be used in a gas separation process as provided herein. The gas separation process can comprise contacting a gas mixture containing at least one contaminant with the organosilica material described herein as prepared according to the methods described herein.

[00263] In various embodiments, the gas separation process can be achieved by swing adsorption processes, such as pressure swing adsorption (PSA) and temperature swing adsorption (TSA). All swing adsorption processes typically have an adsorption step in which a feed mixture (typically in the gas phase) is flowed over an adsorbent to preferentially adsorb a more readily adsorbed component relative to a less readily adsorbed component. A component may be more readily adsorbed because of kinetic or equilibrium properties of the adsorbent. The adsorbent can typically be contained in a contactor that is part of the swing adsorption unit. The contactor can typically contain an engineered structured adsorbent bed or a particulate adsorbent bed. The bed can contain the adsorbent and other materials such as other adsorbents, mesopore filling materials, and/or inert materials used to mitigated temperature excursions from the heat of adsorption and desorption. Other components in the swing adsorption unit can include, but are not necessarily limited to, valves, piping, tanks, and other contactors. Swing adsorption processes are described in detail in U.S. Patent Nos. 8,784,533;

8,784,534; 8,858,683; and 8,784,535, each of which are incorporated herein by reference. Examples of processes that can be used herein either separately or in combination are PSA, TSA, pressure temperature swing adsorption (PTSA), partial purge displacement swing adsorption (PPSA), PPTSA, rapid cycle PSA (RCPSA), RCTSA, RCPPSA and RCPTSA.

[00264] Swing adsorption processes can be applied to remove a variety of target gases, also referred to as "contaminant gas" from a wide variety of gas mixtures.

Typically, in binary separation systems, the "light component" as utilized herein is taken to be the species or molecular component(s) not preferentially taken up by the adsorbent in the adsorption step of the process. Conversely in such binary systems, the "heavy component" as utilized herein is typically taken to be the species or molecular component(s) preferentially taken up by the adsorbent in the adsorption step of the process. However, in binary separation systems where the component(s) that is(are) preferentially adsorbed has(have) a lower molecular weight than the component(s) that is(are) not preferentially adsorbed, those descriptions may not necessarily correlate as disclosed above.

[00265] An example of gas mixture that can be separated in the methods described herein is a gas mixture comprising CH ₄ , such as a natural gas stream. A gas mixture comprising CH ₄ can contain significant levels of contaminants such as H ₂ 0, H ₂ S, C0 ₂ , N ₂ , mercaptans, and/or heavy hydrocarbons. Additionally or alternatively, the gas mixture can comprise NO _x and/or SO _x species as contaminants, such as a waste gas stream, a flue gas stream and a wet gas stream. As used herein, the terms "NO _x ," and "NO _x " species refers to the various oxides of nitrogen that may be present in waste gas, such as waste gas from combustion processes. The terms refer to all of the various oxides of nitrogen including, but not limited to, nitric oxide (NO), nitrogen dioxide (N0 ₂ ), nitrogen peroxide (N ₂ 0 ), nitrogen pentoxide (N ₂ 0 ₅ ), and mixtures thereof. As used herein, the terms "SO _x ," and "SO _x species," refers to the various oxides of sulfur that may be present in waste gas, such as waste gas from combustion processes. The terms refer to all of the various oxides of sulfur including, but not limited to, SO, S0 ₂ , S0 ₃ , S0 ₄ , S ₇ 0 ₂ and S ₆ 0 ₂ . Thus, examples of contaminants include, but are not limited to H ₂ 0, H ₂ S, C0 ₂ , N ₂ , mercaptans, heavy hydrocarbons, NO _x and/or SO _x species.

B. Aromatic Hydrogenation Process

[00266] The organosilica materials made according to the methods described herein can be used as support materials in hydrogenation catalysts. In particular, the hydrogenation catalyst can comprise the organosilica materials as a support material where the organosilica material has at least one catalyst metal incorporated on the pore surface. The at least one catalyst metal may be a Group 8 metal, a Group 9 metal, a Group 10 metal, e.g., Pt, Pd, Ir, Rh, Ru or a combination thereof. The hydrogenation catalyst can further comprise a binder such as, but not limited to, active and inactive materials, inorganic materials, clays, ceramics, activated carbon, alumina, silica, silica- alumina, titania, zirconia, niobium oxide, tantalum oxide, or a combination thereof, particularly, silica-alumina, alumina, titania, or zirconia. These hydrogenation catalysts can be used for both hydrogenation and aromatic saturation of a feedstream.

[00267] In various embodiments, the hydrogenation process can be achieved by contacting a hydrocarbon feedstream comprising aromatics with a hydrogenation catalyst described herein in the presence of a hydrogen-containing treat gas in a first reaction stage operated under effective aromatics hydrogenation conditions to produce a reaction product with reduced aromatics content.

[00268] Hydrogen-containing treat gasses suitable for use in a hydrogenation process can be comprised of substantially pure hydrogen or can be mixtures of other components typically found in refinery hydrogen streams. It is preferred that the hydrogen-containing treat gas stream contains little, more preferably no, hydrogen sulfide. The hydrogen-containing treat gas purity can advantageously be at least about 50% by volume hydrogen, such at least about 75% by volume hydrogen or at least about 90% by volume hydrogen for best results. In many embodiments, the hydrogen- containing stream be substantially pure hydrogen.

[00269] Feedstreams suitable for hydrogenation by the hydrogenation catalyst described herein include any conventional hydrocarbon feedstreams where

hydrogenation or aromatic saturation is desirable. Typically, an input feed for an aromatic saturation process can be generated as a product or side-product from a previous type of hydroprocessing, such as hydrocracking for fuels or lubricant base stock production. A wide range of petroleum and chemical feedstocks can be hydroprocessed. Such feedstreams can include hydrocarbon fluids, diesel, kerosene, lubricating oil feedstreams, heavy coker gasoil (HKGO), de-asphalted oil (DAO), FCC main column bottom (MCB), steam cracker tar. Such feedstreams can also include other distillate feedstreams such as light to heavy distillates including raw virgin distillates, wax-containing feedstreams such as feeds derived from crude oils, shale oils and tar sands. Synthetic feeds such as those derived from the Fischer-Tropsch process can also be aromatically saturated using the hydrogenation catalyst described herein. Typical wax-containing feedstocks for the preparation of lubricating base oils have initial boiling points of about 315°C or higher, and include feeds such as whole and reduced petroleum crudes, hydrocrackates, raffinates, hydrotreated oils, gas oils (such as atmospheric gas oils, vacuum gas oils, and coker gas oils), atmospheric and vacuum residues, deasphalted oils/residua (e.g., propane deasphalted residua, brightstock, cycle oil), dewaxed oils, slack waxes and Fischer-Tropsch wax, and mixtures of these materials. Such feeds may be derived from distillation towers (atmospheric and vacuum), hydrocrackers, hydrotreaters and solvent extraction units, and may have wax contents of up to 50% or more. Exemplary lubricating oil boiling range feedstreams include feedstreams which boil in the range of 650-1100°F. Diesel boiling range feedstreams can include feedstreams which boil in the range of 480-660°F. Kerosene boiling range feedstreams can include feedstreams which boil in the range of 350- 617°F.

[00270] Hydrocarbon feedstreams suitable for use herein also contain aromatics and nitrogen- and sulfur-contaminants. Feedstreams containing up to 0.2 wt. % of nitrogen, based on the feedstream, up to 3.0 wt. % of sulfur, and up to 50 wt. % aromatics can be used in the present process In various embodiments, the sulfur content of the feedstreams can be below about 500 wppm, or below about 300 wppm, or below about 200 wppm, or below about 100 wppm, or below about 50 wppm, or below about 15wppm. The pressure used during an aromatic hydrogenation process can be modified based on the expected sulfur content in a feedstream. Feeds having a high wax content typically have high viscosity indexes of up to 200 or more. Sulfur and nitrogen contents may be measured by standard ASTM methods D2622 (sulfur), and D5453 and/or D4629 (nitrogen), respectively.

[00271] Effective hydrogenation conditions may be considered to be those conditions under which at least a portion of the aromatics present in the hydrocarbon feedstream are saturated, preferably at least about 50 wt. % of the aromatics are saturated, more preferably greater than about 75 wt. %. Effective hydrogenation conditions can include temperatures of from 150°C to 400°C, a hydrogen partial pressure of from 100 to 3000 psig (700 to 20100 kPag), a liquid hourly space velocity (LHSV) of from 0.1 to 10 hr ^"1 , and a hydrogen to feed ratio of from 500 to 10000 scf/B (85 to 1700 Nm ³ /m ³ ).

[00272] Additionally or alternatively, effective hydrogenation conditions may be conditions effective at removing at least a portion of the nitrogen and organically bound sulfur contaminants and hydrogenating at least a portion of said aromatics, thus producing at least a liquid lube boiling range product having a lower concentration of aromatics and nitrogen and organically bound sulfur contaminants than the lube boiling range feedstream.

[00273] Additionally or alternatively, effective hydrogenation conditions may be conditions effective at removing at least a portion of the nitrogen and organically bound sulfur contaminants and hydrogenating at least a portion of said aromatics, thus producing at least a liquid diesel boiling range product having a lower concentration of aromatics and nitrogen and organically bound sulfur contaminants than the diesel boiling range feedstream.

[00274] As stated above, in some instances, the hydrocarbon feedstream (e.g., lube oil boiling range) may be hydrotreated to reduce the sulfur contaminants to below about 500 wppm, particularly below about 300 wppm, particularly below about 200 wppm or particularly below about 100 wppm. In such an embodiment, the process may comprise at least two reaction stages, the first reaction state containing a hydrotreating catalyst operated under effective hydrotreating conditions, and the second containing a hydrogenation catalyst has described herein operated under effective hydrogenation conditions as described above. Therefore, in such an embodiment, the hydrocarbon feedstream can be first contacted with a hydrotreating catalyst in the presence of a hydrogen-containing treat gas in a first reaction stage operated under effective hydrotreating conditions in order to reduce the sulfur content of the feedstream to within the above-described range. Thus, the term "hydrotreating" as used herein refers to processes wherein a hydrogen-containing treat gas is used in the presence of a suitable catalyst that is active for the removal of heteroatoms, such as sulfur, and nitrogen. Suitable hydrotreating catalysts for use in the present invention are any conventional hydrotreating catalyst and includes those which are comprised of at least one Group 8 metal, preferably Fe, Co and Ni, more preferably Co and/or Ni, and most preferably Ni; and at least one Group 6 metal, preferably Mo and W, more preferably Mo, on a high surface area support material, preferably alumina. Additionally or alternatively, more than one type of hydrotreating catalyst can be used in the same reaction vessel. The Group 8 metal may typically be present in an amount ranging from about 2 to 20 wt%, preferably from about 4 to 12 wt%. The Group 6 metal can typically be present in an amount ranging from about 5 to 50 wt%, preferably from about 10 to 40 wt%, and more preferably from about 20 to 30 wt%. All metals weight percents are "on support" as described above.

[00275] Effective hydrotreating conditions may be considered to be those conditions that can effectively reduce the sulfur content of the feedstream (e.g., lube oil boiling range) to within the above-described ranges. Typical effective hydrotreating conditions can include temperatures ranging from about 150°C to about 425°C, preferably about 200°C to about 370° C, more preferably about 230°C to about 350°C Typical weight hourly space velocities ("WHSV") may range from about 0.1 to about 20 hr ^-1 , preferably from about 0.5 to about 5 hr ^-1 . Any effective pressure can be utilized, and pressures can typically range from about 410 to about 7100 kPag (about 4 to about 70 atmospheres), such as about 1000 to about 4100 kPag (about 10 to about 40

atmospheres). In a particular embodiment, said effective hydrotreating conditions may be conditions effective at removing at least a portion of said organically bound sulfur contaminants and hydrogenating at least a portion of said aromatics, thus producing at least a reaction product (e.g., liquid lube oil boiling range product) having a lower concentration of aromatics and organically bound sulfur contaminants than the lube oil boiling range feedstream.

[00276] The contacting of the hydrocarbon feedstream with the hydrotreating catalyst may produce a reaction product comprising at least a vapor product and a liquid product. The vapor product may typically comprise gaseous reaction products, such as H ₂ S, and the liquid reaction product may typically comprise a liquid hydrocarbon having a reduced level of nitrogen and sulfur contaminants. The total reaction product can be passed directly into the second reaction stage, but it may be preferred that the gaseous and liquid reaction products be separated, and the liquid reaction product conducted to the second reaction stage. Thus, in one embodiment, the vapor product and the liquid product may be separated, and the liquid product may be conducted to the second reaction stage. The method of separating the vapor product from the liquid product can be accomplished by any means known to be effective at separating gaseous and liquid reaction products. For example, a stripping tower or reaction zone can be used to separate the vapor product from the liquid product (e.g., liquid lube oil boiling range product). The liquid product thus conducted to the second reaction stage can have a sulfur concentration within the range of about 500 wppm, particularly below about 300 wppm, or particularly below about 200 wppm or particularly below about 100 wppm.

[00277] In still other embodiments, the hydrogenation catalysts described herein can be used in integrated hydroprocessing methods. In addition to the hydrofinishing and/or aromatic hydrogenation/saturation processes involving the hydrogenation catalyst described herein, an integrated hydroprocessing method can also include various combinations of hydrotreating, hydrocracking, catalytic dewaxing (such as

hydrodewaxing), and/or solvent dewaxing. The scheme of hydrotreating followed by hydrofinishing described above represents one type of integrated process flow. Another integrated processing example is to have a dewaxing step, either catalytic dewaxing or solvent dewaxing, followed by hydroprocessing with the hydrogenation catalysts described herein. Still another example is a process scheme involving hydrotreating, dewaxing (catalytic or solvent), and then hydroprocessing with the hydrogenation catalysts described herein. Yet another example is hydroprocessing with the

hydrogenation catalysts described herein followed by dewaxing (catalytic or solvent). Alternatively, multiple hydrofinishing and/or aromatic hydrogenation steps can be employed with hydrotreatment, hydrocracking, or dewaxing steps. An example of such a process flow is hydrofinishing, dewaxing (catalytic or solvent), and then

hydrofinishing again, where at least one of the hydrofinishing steps may use a hydrogenation catalysts described herein. For processes involving catalytic dewaxing, effective catalytic dewaxing conditions can include temperatures of from 150°C to 400°C, preferably 250°C to 350°C, pressures of from 100 to 3000 psig (700 to 21000 kPag), such as from 200 to 2500 psig (from 1400 to 17500 kPag), liquid hourly space velocities of from 0.1 to 10 hr ^-1 , such as 0.1 to 5 hr ^-1 ; and hydrogen treat gas rates from 250 to 10000 scf/B (from 40 to 1700 Nm ³ /m ³ ), such as from 500 to 5000 scf/B (from 85 to 850 Nm ³ /m ³ ). Any suitable dewaxing catalyst may be used. [00278] In embodiments where the product of an aromatic saturation process will be a lubricant base oil, the input feed should also have suitable lubricant base oil properties. For example, an input feed intended for use as a Group I or Group II base oil can have a viscosity index (VI) of at least about 80, preferably at least about 90 or at least about 95. An input feed intended for use as a Group 1+ base oil can have a VI of at least about 100, while an input feed intended for use as a Group 11+ base oil can have a VI of at least 110. The viscosity of the input feed can be at least 2 cSt at 100°C, or at least 4 cSt at 100°C, or at least 6 cSt at 100°C.

Table 1. Physical properties of polymers made from 1, 1, 3,3,5, 5-hexaethoxy-l, 3,5- trisilacyclohexane ([(EtO) ₂ SiCH ₂ ] ₃ ) and/or colloidal silica

* Examples 1-8 contain LUDOX® AS-40; Examples 9-13 contain LUDOX® HS-40; both contain -40% silica by weight.

[00324] The data in Table 1 above appears to show increasing BET surface area and pore volume, and decreasing average pore diameter with increasing content of Formula (I) monomer and/or with decreasing content of colloidal silica. A homopolymer organosilica containing only Formula (I) monomers is provided for comparison, as is a homopolymer containing only colloidal silica monomer.

[00325] Figure 1 shows XRD spectra for Examples 2-8, using LUDOX® AS-40 colloidal silica, and Figure 2 shows XRD spectra for Examples 9-13, using LUDOX® HS-40 colloidal silica. These XRD results appeared to show enhanced low angle peak intensity and a shift to higher diffraction angle at higher contents of Formula (I) monomer and/or at lower contents of colloidal silica.
