HYDROCARBON CONVERSION PROCESSES AND CATALYSTS USED THEREIN

摘要

This invention relates to catalyst compositions useful in converting hydrocarbonaceous oils. The catalyst comprises an ultra stable Y zeolite base, wherein said Y zeolite has a unit cell size greater than about 24.55 .ANG. and a crystal size less than about 2.8 microns, an amorphous cracking component, a binder, and a catalytic amount o f hydrogenation component selected from the group consisting of a Group VI metal, a Group VIII metal, and mixtures thereof. The invention also relates to processes that are suitable for the catalyst use therein.
