Abstract
A composition of matter, suitable as cracking catalyst, comprises zeolite, silica matrix and vanadium oxide(s) at a level of at least 0.2 weight-% V. A process for preparing the above composition of matter comprises the steps of contacting zeolite in a silica matrix with at least one vanadium compound and calcining the thus contacted material. A process for cracking substantially liquid hydrocarbon-containing feed streams, which contain at least about 5 ppmw vanadium, in the presence of the above composition of matter as catalyst, is provided.
