Abstract
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 C3 and C4 olefins, and a low pour point distillate product.
