Abstract
A catalyst for catalytically cracking hydrocarbon oils contains a substrate comprising alumina and a molecular sieve, characterized in that the pore distribution of said catalyst is 5-70% of the <2 nm pores, 5-70% of the 2-4 nm pores, 0-10% of the 4-6 nm pores, 20-80% of the 6-20 nm pores, and 0-40% of the 20-100 nm pores, based on the pore volume of pores having a size of no more than 100 nm. The catalyst of this invention has a large BET pore volume, a high capacity for cracking heavy oils, and a high capacity for resisting coking.
