Abstract
An IM-5 zeolite that is modified by adding phosphorus that is optionally dealuminified, preferably in aluminosilicic form, and that contains at most 10% by weight of phosphorus, a composition that contains it, its processes for preparation and its application to catalytic cracking of hydrocarbon feedstocks are described.
Claims22
A catalytic composition comprising:
- I. at least one IM-5-P phosphorus zeolite comprising silicon and at least one additional framework element selected from the group consisting of Al, Fe, Ga, Ti, and B, and not more than 10% by weight of phosphorus;
- II. at least one Y zeolite having a faujasite structure;
- and
- III. at least one matrix.
An IM-5-P phosphorus zeolite comprising silicon and at least one additional framework element selected from the group consisting of Al, Fe, Ga, Ti, and B and about 2-3% by weight of phosphorus.
