A cracking catalyst, which contains alumina, phosphorus and molecular sieve, with or without clay, wherein said alumina is &#x3b7;-alumina or a mixture of &#x3b7;-alumina and &#x3c7;-alumina and/or &#x3b3;-alumina, and wherein the catalyst contains, on the basis of the total amount of the catalyst, 0.5-50 wt % of &#x3b7;-alumina, 0-50 wt % of &#x3c7;-alumina and/or &#x3b3;-alumina, 10-70 wt % of molecular sieve, 0-75 wt % of clay, and 0.1-8 wt % of phosphorus, measured as PO. 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.

Cracking catalyst and a process for preparing the same

A hydrocarbon conversion catalyst, which comprises, based on the total weight of the catalyst, 1-60 wt % of a zeolite mixture, 5-99 wt % of a thermotolerant inorganic oxide and 0-70 wt % of clay, wherein said zeolite mixture comprises, based on the total weight of said zeolite mixture, 1-75 wt % of a zeolite beta modified with phosphorus and a transition metal M, 25-99 wt % of a zeolite having a MFI structure and 0-74 wt % of a large pore zeolite,
