Title: Two-catalyst hydrocracking process

Patent ·
OSTI ID:5088273

A process is described for the hydrocracking of a hydrocarbon stream boiling above a temperature of about 300/sup 0/F (149/sup 0/C) and containing a substantial amount of organic nitrogen-containing compounds, which process comprises: contacting said stream in a frist reaction zone under hydrocracking conditions and in the presence of hydrogen with a first catalyst comprising a hydrogenation component comprising nickel and molybdenum or nickel and tungsten and a co-catalytic acidic cracking support comprising an ultrastable, large-pore crystalline aluminosilicate material suspended in and distributed throughout a matrix of silica-alumina to provide a first hydrocracked effluent, said hydrogenation component of said first catalyst being present in the elemtnal form, as oxides, as sulfides, or mixtures thereof; contacting said first hydrocracked effluent in a second reaction zone under hydrocracking conditions and in the presence of hydrogen with a second catalyst comprising a hydrogenation component comprising cobalt and molybdenum and a co-catalytic acidic cracking support comprising an ultrastable, large-pore crystalline aluminosilicate material suspended in and distributed throughout a matrix of silica-alumina to provide a second hydrocracked effluent,said hydrogenation component of said second catalyst being present in the elemental form, as oxides, as sulfides, or mixtures thereof; and recovering useful products from said second hydrocracked effluent.
