Hydrocracking Catalyst Containing Beta and Y Zeolites, and Process for its use to make Distillate

摘要

Increased selectivity of middle distillate and increased catalyst activity are obtained in a hydrocracking process by the use of a catalyst containing a hydrogenation component, a beta zeolite having an overall silica to alumina mole ratio of less than 30 and a SF₆ adsorption capacity of at least 28 wt-%, a Y zeolite having a unit cell size of from 24.25 to 24.32 angstrom, and a support.
