Abstract
The catalytic cracking catalyst contains a molecular sieve and an alumina substrate material. The alumina substrate material has a crystalline phase structure of γ-alumina. Based on the volume of pores with a diameter of 2-100 nm, the pore volume of the pores with a diameter of 2-5 nm accounts for 0-10%, the pore volume of the pores with a diameter of more than 5 nm and not more than 10 nm accounts for 10-25%, and the pore volume of the pores with a diameter of more than 10 nm and not more than 100 nm accounts for 65-90%.
