1. 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 in which the catalyst is movable, then the reaction product and the spent catalyst are taken from said reactor for separation by stripping, the separated spent catalyst is returned into the reactor for recycle after regenerated by air burning, and the separated reaction product is fractionated to give light olefins, gasoline, diesel, heavy oil and other saturated hydrocarbons with low molecular weight, characterized in that 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)Na2O.(0.5-10)Al2O3.(1.3-10)P2O5.(0.7-15)MxOy.(64-97)SiO2, in which the transition metal M is Cu; 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. |
