ABSTRACT:
The process comprises contacting a hydrocarbon feedstock containing a substantial amount of organic nitrogen-containing compounds in a first reaction zone under hydrocracking conditions and in the presence of hydrogen with a first catalyst comprising nickel and molybdenum or nickel and tungsten, their oxides, and/or their sulfides on a co-catalytic acidic cracking support comprising ultrastable, large-pore crystalline alumino-silicate material and a silica-alumina matrix to produce a first hydrocracked effluent and contacting said first hydrocracked effluent in a second reaction zone under hydrocracking conditions and in the presence of hydrogen with a second catalyst comprising cobalt and molybdenum, their oxides, and/or their sulfides on a co-catalytic acidic cracking support comprising ultrastable, large-pore crystalline aluminosilicate material and a silica-alumina matrix to produce a second hydrocracked effluent. Preferably, the first catalyst comprises nickel and tungsten deposed on the co-catalytic acidic cracking support.
In one embodiment of the process, the second catalyst is a catalyst that has been deactivated and then regenerated prior to its use in the process.
