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.
A catalytic composition for use in a hydrocracking process, which catalytic composition comprises cobalt and molybdenum on a co-catalytic solid acidic support comprising ultrastable, large-pore crystalline aluminosilicate material and a silica-alumina cracking catalyst, a substantial amount of said ultrastable, large-pore crystalline aluminosilicate material being characterized by well-defined hydroxyl infrared bands near 3700 cm.sup..sup.-1 and near 3625 cm.sup..sup.-1, said ultrastable, large-pore crystalline aluminosilicate material being characterized further by a sodium content that is less than one percent, a maximum cubic unit cell dimension of 24.55 A, and a superior ability to withstand repeated wetting-drying cycles.
A catalytic composition for use in a hydrocracking process, which catalytic composition comprises cobalt and molybdenum on a co-catalytic solid acidic support comprising ultrastable, large-pore crystalline aluminosilicate material and a silica-alumina cracking catalyst, said cobalt and said molybdenum being present as their oxides, said ultrastable, large-pore crystalline aluminosilicate material being suspended in a porous matrix of said silica-alumina cracking catalyst, a substantial amount of said ultrastable, large-pore crystalline aluminosilicate material being characterized by well-defined hydroxyl infrared bands near 3700 cm.sup..sup.-1 and near 3626 cm.sup..sup.-1, said ultrastable, large-pore crystalline aluminosilicate material being characterized further by a sodium content that is less than one weight percent, a maximum cubic unit cell dimension of 24.55 A, and a superior ability to withstand repeated wetting-drying cycles.
A catalytic composition for use in a hydrocracking process, which catalytic composition comprises a Group VI metal and a Group VIII metal, oxides of a Group VI metal and a Group VIII metal, or mixtures thereof on a co-catalytic solid acidic support comprising ultrastable, large-pore crystalline aluminosilicate material and a silica-alumina cracking catalyst, a substantial amount of said ultrastable, large-pore crystalline aluminosilicate material being characterized by well-defined hydroxyl infrared bands near 3700 cm.sup..sup.-1 and near 3625 cm.sup..sup.-1, said ultrastable, large-pore crystalline aluminosilicate material being characterized further by a sodium content that is less than one percent, a maximum cubic unit cell dimension of 24.55 A, and a superior ability to withstand repeated wetting-drying cycles.
