Disclosed is a hydrocracking process wherein the feedstock is contacted in a first reaction zone with a first reaction zone catalyst comprising a nickel component and a tungsten component deposed on a support component consisting essentially of an alumina component and a crystalline molecular sieve component. The effluent from the first reaction zone effluent is then contacted in a second reaction zone with a second reaction zone catalyst comprising a cobalt component and a molybdenum component deposed on a support component comprising an alumina component and a crystalline molecular sieve component.

Two-catalyst hydrocracking process

Disclosed is a hydrocracking process wherein the feedstock is contacted in a first reaction zone with a first reaction zone catalyst comprising a nickel component and a tungsten component deposed on a support component consisting essentially of an alumina component and a crystalline molecular sieve component. The effluent from the first reaction zone effluent is then contacted in a second reaction zone with a second reaction zone catalyst comprising a molybdenum component deposed on a support component comprising an alumina component and a crystalline molecular sieve component.

The catalyst comprises a physical particle-form mixture of a Component A and a Component B, said Component A comprising at least one Group VIII noble metal, preferably platinum, deposed on a solid catalyst support material providing acidic catalytic sites, said Component B consisting essentially of a crystalline borosilicate molecular sieve, and said catalyst having been prepared by thoroughly and intimately blending finely-divided particles of said Components A and B to provide a thoroughly-blended composite. The catalyst can be employed suitably in hydrocarbon conversion processes. In particular, the catalyst can be employed in a process for the reforming of a hydrocarbon stream. More particularly, the catalyst can be used as the second catalyst in a two-catalyst reforming process.
