Hydrocracking process with improved distillate selectivity with high silica large pore zeolites

摘要

A hydrocracking process in which improved selectivity for the production of distillate range (165 DEG C.-343 DEG C.) products is obtained by the use of a catalyst containing a highly siliceous large pore zeolite as the acidic component. Suitable zeolites include zeolites, Y, ZSM-20 and beta with structural silica:alumina ratios of at least 50:1.
