Disclosed is a hydrocracking process wherein the feedstock is first contacted with a first catalyst containing a nickel component and a tungsten component supported on a support containing alumina and a crystalline molecular sieve followed by subsequent contact with a second hydrocracking catalyst containing a cobalt component and a molybdenum component supported on a support containing silica-alumina and a crystalline molecular sieve and the first catalyst. This subsequent contact with the second and first catalysts is carried out either serially or in one step wherein the first and second catalysts are physically mixed.

A process for hydrocracking a hydrocarbon feedstock with hydrogen at hydrocracking conversion conditions in a plurality of reaction zones in series which comprises: a. contacting said feedstock in a first reaction zone with a first hydrocracking catalyst comprising a nickel component and a tungsten

A process for hydrocracking a hydrocarbon feedstock with hydrogen at hydrocracking conversion conditions in a plurality of reaction zones in series which comprises: a. contacting said feedstock in a first reaction zone with a first hydrocracking 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; b. contacting the effluent from said first reaction zone in a second reaction zone with a second hydrocracking 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. c. contacting the effluent from said second reaction zone in a third reaction zone with said first hydrocracking catalyst.
