    摘要: A process for the catalytic conversion of hydrocarbons, said process comprising the following steps: a feedstock of hydrocarbons is contacted with a hydrocarbon-converting catalyst to conduct a catalytic cracking reaction in a reactor, then the reaction products are taken from said reactor and fractionated to give light olefins, gasoline, diesel, heavy oil and other saturated hydrocarbons with low molecular weight, wherein said hydrocarbon-converting catalyst 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, wherein the anhydrous chemical formula of the zeolite beta modified with phosphorus and the transition metal M is represented in the mass percent of the oxides as (0-0.3)Na 2 O·(0.5-10)Al 2 O 3 ·(1.3-10)P 2 O 5 ·(0.7-15)M x O y ·(64-97)SiO 2 , in which the transition metal M is one or more selected from the group consisting of Fe, Co, Ni, Cu, Mn, Zn and Sn; x represents the atom number of the transition metal M, and y represents a number needed for satisfying the oxidation state of the transition metal M. The process of the present invention has a higher ability to convert petroleum hydrocarbon in a higher yield for light olefins, particularly for propylene.
