Abstract
Catalysts including at least one microporous material (e.g., zeolite), an organosilica material binder, and at least one catalyst metal are provided herein. Methods of making the catalysts, preferably without surfactants and processes of using the catalysts, e.g., for aromatic hydrogenation, are also provided herein.
Claims24
A catalyst comprising:
- (i) at least one microporous material, wherein the microporous material is a zeolite, a molecular sieve comprising aluminophosphate and/or silicoaluminophosphate, or combinations thereof;
- (ii) a porous organosilica material binder, which is a polymer comprising independent units of a monomer selected from the group consisting of:
- (a) a monomer of Formula [Z15Z16SiCH2]3 (I), wherein each Z15 represents a hydroxyl group, a C1-C4 alkoxy group or an oxygen atom bonded to a silicon atom of another monomer and each Z16 represents a hydroxyl group, a C1-C4 alkoxy group, a C1-C4 alkyl group, or an oxygen atom bonded to a silicon atom of another monomer;
- and
- (b) a cyclic polyurea monomer of Formula
- wherein each R1 independently is a X5OX6X7SiX8 group, wherein each X5 represents a hydrogen atom, a C1-C4 alkyl group, or a bond to a silicon atom of another monomer unit;
- X6 and X7 each independently represent a hydroxyl group, a C1-C4 alkyl group, a C1-C4 alkoxy group, or an oxygen atom bonded to a silicon atom of another monomer unit;
- and each X8 represents a C1-C8 alkylene group bonded to a nitrogen atom of the cyclic polyurea;
- and
- (iii) at least one catalyst metal, wherein the at least one catalyst metal is incorporated into the microporous material, the porous organosilica material binder and/or a catalyst particle comprising the at least one microporous material bound with the polymer,
- and the porous organosilica material binder is present in the catalyst in an amount of at least about 1.0 wt % based on the total weight of the microporous material and the porous organosilica material binder.
