CATALYTIC CRACKING WITH A MIXTURE OF FAUJASITE-TYPE ZEOLITES AND ZEOLITE (BETA)

Hydrocarbon feeds are cracked, with simultaneous dewaxing, by contact under cracking conditions in the absence of added hydrogen with a catalyst comprising zeolite beta and a faujasite zeolite. The process yields a higher octane gasoline, increased yields of C3 and C4 olefins, and lower pour point d...

Zusammenfassung:	Hydrocarbon feeds are cracked, with simultaneous dewaxing, by contact under cracking conditions in the absence of added hydrogen with a catalyst comprising zeolite beta and a faujasite zeolite. The process yields a higher octane gasoline, increased yields of C3 and C4 olefins, and lower pour point distillate product.
