Abstract
Abstract Heavy oils are simultaneously subjected to hydrocracking and dewaxing using a catalyst comprising zeolite beta and an X or Y or other faujasite zeolite together with a hydrogenation component. The process is able to effect a bulk conversion of the oil while, at the same time, yielding a low pour point product.
