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.

A cracking process comprising the step of (A) contacting a substantially liquid hydrocarbon-containing feed stream which has an initial boiling point under atmospheric pressure conditions in excess of about 500°F. and which contains at least about 5 ppmw vanadium with a catalyst composition comprising (a) zeolite, (b) matrix material, in which zeolite is embedded, consisting esentially of silica, and (c) at least one vanadium oxide at a level of at least about 0.2 weight-% V, under such cracking conditions as to obtain at least one liquid product stream having a lower initial boiling point and a higher API gravity than said feed stream.
