摘要

Increased selectivity of middle distillate and/or increased catalyst activity are obtained in a hydrocracking process by the use of a catalyst containing a beta zeolite and a Y zeolite having a unit cell size of from 24.25 to 24.32 angstrom. The catalyst may also contain an additional Y zeolite having a unit cell size of from 24.33 to 24.38 angstrom.
