Abstract
Abstract Hydrocracking catalysts are disclosed consisting essentially of a physical, particle-form mixture of (1) a crystalline alumino-silicate component having a sodium content of less than 4 percent by weight, and (2) a hydrogenation component comprising a predominant proportion of a porous support, other than a crystalline aluminosilicate, and a minor proportion of at least one constituent exhibiting hydrogenation activity. Hydrocracking processes using such catalysts are also disclosed.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
103 words
A hydrocracking catalyst composition prepared by intimately admixing a Y zeolite component with an amorphous component selected from the class consisting of alumina, magnesia and hydrogen montmorillonite clays, and consolidating the resulting mixture into granular form, at least about 20% of the exchange capacity of the zeolite component appearing in the final composition being decationized and/or satisfied by hydrogen ions, the final composition also containing a minor proportion of at least one Group VI-B and/or Group VIII metal, metal oxide or metal sulfide hydrogenating promoter supported on said amorphous component, said amorphous component comprising at least about 10 weight-percent of the final composition.
Claim 2
Dependent Claim
103 words
A hydrocracking catalyst composition prepared by intimately admixing a Y zeolite component with an amorphous component selected from the class consisting of alumina, magnesia and hydrogen montmorillonite clays, and consolidating the resulting mixture into granular form, at least about 20% of the exchange capacity of the zeolite component appearing in the final composition being decationized and/or satisfied by hydrogen ions, the final composition also containing a minor proportion of at least one Group VI-B and/or Group VIII metal, metal oxide or metal sulfide hydrogenating promoter supported on said amorphous component, said amorphous component comprising at least about 10 weight-percent of the final composition.
Claim 3
Dependent Claim
27 words
A composition as defined in claim 1 wherein said amorphous component is alumina, and said hydrogenating promoter is a Group VIII metal, metal oxide or metal sulfide.
Claim 4
Dependent Claim
31 words
A composition as defined in claim 1 wherein at least about 40% of the exchange capacity of said zeolite component in the final composition is decationized and/or satisfied by hydrogen ions.
Claim 5
Dependent Claim
66 words
A catalyst composition comprising a copelleted composite of: 1. a hydrogen and/or decationized Y zeolite; and 2. at least about 10 weight-percent of a porous, relatively inert, thermally stable, inorganic adjuvant originally in the form of a powder having an average particle size larger than the average crystal size of said zeolite component, upon which is deposited a minor proportion of a transitional metal hydrogenating component.
Claim 6
Dependent Claim
66 words
A catalyst composition comprising a copelleted composite of: 1. a hydrogen and/or decationized Y zeolite; and 2. at least about 10 weight-percent of a porous, relatively inert, thermally stable, inorganic adjuvant originally in the form of a powder having an average particle size larger than the average crystal size of said zeolite component, upon which is deposited a minor proportion of a transitional metal hydrogenating component.
Claim 7
Dependent Claim
28 words
A composition as defined in claim 4 wherein at least about 40% of the exchange capacity of said Y zeolite component is decationized and/or satisfied by hydrogen ions.
Claim 8
Dependent Claim
12 words
A composition as defined in claim 4 wherein said adjuvant is alumina.
Claim 9
Dependent Claim
28 words
A composition as defined in claim 4 wherein said hydrogenating component is selected from the class consisting of the Group VIII metals, and the oxides and sulfides thereof.
