CATALYTIC CRACKING WITH A MIXTURE OF FAUJASITE-TYPE ZEOLITES AND ZEOLITE .beta.

摘要

ABSTRACTHydrocarbon feeds are cracked, with simultaneousdewaxing, by contact under cracking conditions in theabsence of added hydrogen with a catalyst comprisingzeolite beta and a faujasite zeolite. The process yieldsa higher octane gasoline, increased yields of C3 and C4olefins, and lower pour point distillate product.
