Abstract:
A catalytic cracking catalyst has a rare earth modified Y-type molecular sieve, an additive-containing alumina binder, and a clay. The rare earth modified Y-type molecular sieve has a rare earth oxide content of about 4-12 wt %, a phosphorus content of about 0-10 wt %, a sodium oxide content of no more than about 1.0 wt %, a total pore volume of about 0.36-0.48 mL/g, a percentage of the pore volume of secondary pores having a pore size of 2-100 nm to the total pore volume of about 20-40%, a lattice constant of about 2.440-2.455 nm, a percentage of non-framework aluminum content to the total aluminum content of no more than about 10%, a lattice collapse temperature of not lower than about 1060° C., and a ratio of B acid to L acid in the total acid content of the modified Y-type molecular sieve of no less than about 3.50.
