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. The invention also provides such catalysts.
