ABSTRACT:
The catalyst comprises the oxides of cobalt and molybdenum deposited on a co-catalytic acidic cracking support comprising ultrastable, large-pore crystalline aluminosilicate material and a silica-alumina cracking catalyst. This catalyst may be used in a hydrocracking process or a combination process for converting petroleum hydrocarbons to gasoline blending stock having an unleaded research octane number greater than about 105. The hydrocracking process comprises contacting the catalyst in a hydrocracking reaction zone under hydrocracking conditions with a feedstock having an initial boiling point of at least 350.degree. F. The combination process comprises treating the hydrocarbons in the hydrocracking process, selectively solvent-extracting the aromatics from the resultant hydrocracked product to obtain an aromatic extract and a non-aromatic raffinate, catalytically reforming the non-aromatic raffinate, and blending the resultant catalytic reformate with aromatic extract.
