  • Cracking catalyst and a process for preparing the same
    Patent number: 9175230
    Abstract: A cracking catalyst, which contains alumina, phosphorus and molecular sieve, with or without clay, wherein said alumina is ?-alumina or a mixture of ?-alumina and ?-alumina and/or ?-alumina, and wherein the catalyst contains, on the basis of the total amount of the catalyst, 0.5-50 wt % of ?-alumina, 0-50 wt % of ?-alumina and/or ?-alumina, 10-70 wt % of molecular sieve, 0-75 wt % of clay, and 0.1-8 wt % of phosphorus, measured as P2O5. The catalyst not only has higher cracking activity and higher cracking ability for cracking heavy oil, but also improves significantly quality and yield of gasoline, LCO and LPG in cracking products.
