CA 2170258

A novel catalyst composition and process for catalytic cracking of a hydrocarbon oil. The catalyst comprises zoolite beta and a shape selective cracking component, preferably ZSM-5, and may include conventional cracking catalyst components such as zeolite Y. These components may be present in one particle or as a blend of separate particle additives. The composition increases light olefin yields and gasoline octane as compared to catalyst containing either, but not both of, ZSM-5 and zeolite beta.

Nouvelle composition catalytique et nouveau procédé de craquage catalytique d'une huile d'hydrocarbure. Le catalyseur comprend une zéolite bêta et un constituant de craquage à sélection de forme, de préférence ZSM-5, et peut comprendre des constituants de catalyseur de craquage classique tels que la zéolite Y. Ces constituants peuvent être présents dans une particule ou sous forme d'un mélange d'additifs particulaires séparés. Cette composition accroît les rendements en oléfines légères et en octane d'essence par rapport aux catalyseurs contenant le constituant ZSM-5 ou de la zéolite bêta mais non les deux.
