Abstract

A hydrocracking process, of especial use in the production of a relatively high yield of middle distillate products along with a smaller but still significant yield of gasoline from high boiling gas oils and the like, comprises contacting a gas oil or other hydrocarbon feedstock under hydrocracking conditions with a novel catalyst comprising one or more hydrogenation components on a support material comprising, in combination, a dispersion of silica-alumina in alumina and a zeolite of the Y crystalline structure but having a silica-to-alumina ratio above about 6.0.
