    • A catalyst for converting hydrocarbons, which catalyst contains, based on the weight of the catalyst, 1-60% by weight of a zeolite, 0.1-10% by weight of an assistant catalytic component, 5-98% by weight of a thermotolerant inorganic oxide, and 0-70% by weight of a clay in terms of the oxide. Said zeolite is a MFI-structured zeolite containing phosphor and transition metal(s) or a mixture of said zeolite and a macroporous zeolite, which comprises, based on the weight of the mixture, 75-100% by weight of said MFI-structured zeolite containing phosphor and transition metal(s) and 0-25% by weight of the macroporous zeolite. In terms of the mass of the oxide, said MFI-structured zeolite containing phosphor and transition metal(s) has the following anhydrous chemical formula: €ƒ€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ(0-0.3)Na 2 O · (0.3-5.5)Al 2 O 3 · (1.0-10)P 2 O 5 · (0.7-15)M1 x O y · (0.01-5)M2 m O n · (0-10)RE 2 O 3 · (70-97)SiO 2 €ƒ€ƒ€ƒ€ƒ€ƒI or €ƒ€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ(0-0.3)Na 2 O · (0.3-5)Al 2 O 3 · (1.0-10)P 2 O 5 · (0.7-15)M p O q · (0-10)RE 2 O 3 · (70-98)SiO 2 €ƒ€ƒ€ƒ€ƒ€ƒII Said assistant catalytic component is one or more selected from the group consisting of the alkali earth metals, Group IVB metals, non-noble metals of Group VIII, and rare earth metals of the Periodic Table of the Elements. This catalyst has a higher ability to convert petroleum hydrocarbons and higher yields for propylene, ethylene, and light aromatics.
