Mild hydrocracking with a zeolite catalyst containing silica-alumina

Patent ·
OSTI ID:5432930

A process is described for mild hydrocracking a hydrocarbon oil having a substantial proportion of components boiling below about 1,100/sup 0/F, the process comprising contacting the hydrocarbon oil under conditions of elevated temperature and a hydrogen pressure less than about 1,500 p.s.i.g. with a particulate catalyst comprising at least one hydrogenation component, a crystalline aluminosilicate zeolite having catalytic activity for cracking hydrocarbons, and a dispersion of silica-alumina in a matrix consisting essentially of alumina, the conditions being such as to yield about a 10 to about a 50 volume percent conversion of the hydrocarbon oil fraction boiling above 700/sup 0/F to hydrocarbon products boiling at or below 700/sup 0/F.
