Abstract
Heavy oils are simultaneously subjected to cracking and dewaxing in the absence of added hydrogen using a catalyst comprising Zeolite Beta and an X or Y or other faujasite zeolite. The process is able to effect a bulk conversion of the oil, while, at the same time, yielding a higher octane gasoline, increased yields of C.sub.3 and C.sub.4 olefins, and a low pour point distillate product.
Claims34
A catalytic cracking process which comprises catalytically cracking a hydrocarbon feed in the absence of added hydrogen with a cracking catalyst comprising zeolite beta component and a faujasite component comprising at least one crystalline aluminosilicate of the faujasite structure, the weight ratio of the faujasite component to the zeolite beta component being from 1:25 to 20:1.
A process for cracking a gas oil to produce a gasoline product of improved octane rating, which comprises catalytically cracking a hydrocarbon feed in the absence of added hydrogen with a cracking catalyst comprising zeolite beta component and a faujasite component comprising at least one crystalline aluminosilicate of the faujasite structure, the weight ratio of the faujasite component to the zeolite beta component being from 1:2 to 20:1.
A process for simultaneously cracking and dewaxing a hydrocarbon feed to produce cracked products including distillate of improved cetane number and pour point, the process comprising catalytically cracking a hydrocarbon feed in the absence of added hydrogen with a cracking catalyst comprising zeolite beta component and a faujasite component comprising at least one crystalline aluminosilicate of the faujasite structure, the weight ratio of the faujasite component to the zeolite beta component being from 1:25 to 3:1.
