Claim 11:
12. The catalytic cracking catalyst according to claim 10, wherein the phosphorus-aluminum inorganic binder is an aluminophosphate gel and/or a first clay-containing phosphorus-aluminum inorganic binder;
the first clay-containing phosphorus-aluminum inorganic binder comprises, based on a dry weight of the first clay-containing phosphorus-aluminum inorganic binder: 15-40 wt % of an aluminum component calculated as Al2O3, 45-80 wt % of a phosphorus component calculated as P2O5, and more than 0 and not more than 40 wt % of the first clay on a dry basis, wherein the first clay-containing phosphorus-aluminum inorganic binder has a weight ratio of P/Al of 1.0-6.0, a pH value of 1-3.5, and a solid content of 15-60 wt %; and the first clay comprises at least one selected from kaolin, sepiolite, attapulgite, rectorite, montmorillonite, and diatomite; and
the second inorganic binder comprises at least one of pseudo-boehmite, alumina sol, silica-alumina sol, and water glass.
