Abstract
Abstract A hydrocracking catalyst composition comprising a mixture of (1) a hydrogenation component deposited on a crystalline aluminosilicate, and (2) a matrix material impregnated with a hydrogenation component, a method for making the same comprising impregnating the matrix component with a diphase medium consisting of hydrogenation metals present as finely divided precipitate in a salt solution, or a medium consisting of a solution of hydrogenation metals, and admixing the resultant wet mix with a component as defined in (1), and hydrocracking in the presence thereof.

Claims Analysis
Total Claims: 19
Claim 1
Independent Claim
220 words
A method for preparing a hydrocracking catalyst composition comprising a mixture of (1) a crystalline aluminosilicate of ordered internal structure and uniform pore diameter impregnated with a hydrogenation metal component selected from the group consisting of an oxide of a metal of Groups VI and VIII of the Periodic Table, a sulfide of a metal of Groups VI and VIII of the Periodic Table, and a metal of Groups VI and VIII of the Periodic Table and mixtures thereof, and (2) a matrix material impregnated with a hydrogenation metal component selected from the group consisting of an oxide of a metal of Groups VI and VIII of the Periodic Table, a sulfide of a metal of Groups VI and VIII of the Periodic Table, and a metal of Groups VI and VIII of the Periodic Table and mixtures thereof, which method comprises preparing an impregnating diphase medium consisting of said hydrogenation metal present as a finely divided precipitate in a salt solution thereof, impregnating separately the aluminosilicate component and the matrix component with said impregnating medium and thereafter combining the resultant impregnated wet matrix mix with the resultant impregnated crystalline aluminosilicate component, said matrix component not being subjected to heat, at any time, in a way that destroys its essential plasticity before its admixture with said impregnated crystalline aluminosilicate component.

Claim 6
Dependent Claim
20 words
The method of claim 6 wherein components (1) and (2) are in admixture in a weight ratio of about 1:20.
Claim 7
Dependent Claim
20 words
The method of claim 6 wherein components (1) and (2) are in admixture in a weight ratio of about 20:1.
Claim 8
