HYDROCRACKING WITH ULTRA LARGE PORE SIZE CATALYSTS

摘要

A hydrocracking process uses a catalyst which is based on an ultra-large por e crystalline material. The crystalline material has pores of at least 13 .ANG. diameter arranged in a uniform manner and exhibits unusually large sorption capacity demonstrated by its benzene adsorption capacity of greater than 15 grams benzene/100 grams ( 50 tort and 25.degree.C). A preferred form of the catalyst has a hexagonal structure which exhibits a hexagonal electron diffraction pattern than can be indexed with a d100 value greater than 18 .ANG.. In one embodiment of this invention, the catalyst additionall y comprises a zeolite component. The hydrocracking catalysts based on these materials are capable of producing hydrocracked products of improved quality with lower nitrogen and aromatic content.
