ABSTRACT:
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.
