ABSTRACT:
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 molybdenum component deposed on a support consisting essentially of a refractory inorganic oxide. The effluent from the first reaction zone is then contacted in a second reaction zone with a second 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 second reaction zone effluent is then contacted in a third reaction zone with a third reaction zone catalyst comprising a cobalt component and a molybdenum component deposed on a support component comprising a silica-alumina component and a crystalline molecular sieve component.
