This invention discloses a cracking catalyst, which comprises an appropriate amount of molecular sieve, and aluminum oxide containing 0.5-40 wt. % of additive. The cracking catalyst is prepared by: (1) mixing pseudoboehmite, water and acid by stirring to obtain mixed slurry; (2) aging the mixed slurry at room temperature to 90 deg.C for 0-24 h; (3) mixing the product of step 2 with the additive; (4) mixing the product of step 3 with the molecular sieve, drying and torrefying. The weight ratio of the acid to aluminum oxide in pseudoboehmite is 0.01-0.5. The cracking catalyst has better heavy oil reforming performance. |
