Claim:
A zeolite-containing catalyst for converting hydrocarbons, said catalyst comprising: a zeolite, a thermotolerant inorganic oxide, and optionally a clay, characterized in that said zeolite is a MFI-structured zeolite containing phosphor and at least one transition metal or a mixture of said MFI-structured zeolite containing phosphor and said at least one transition metal with a macroporous zeolite, which comprises, based on the weight of the mixture, 75-100% by weight of said MFI-structured zeolite containing phosphor and said at least one transition metal and 0-25% by weight of the macroporous zeolite; wherein in the terms of the mass of the oxide, said MFI-structured zeolite containing phosphor and said at least one transition metal has an anhydrous chemical formula selected from: (0-0.2)Na 2 O.(0.9-5)Al 2 O 3 .(1.5-7)P 2 O 5 .(0.9-10)M1 x O y .(0.5-2)M2 m O n .(0.5-10)RE 2 O 3 .(82-92)SiO 2 I or (0-0.2)Na 2 O(0.9-5)Al 2 O 3 (1.5-7)P 2 O 5 (0.9-10)M p O q (0.5-10)RE 2 O 3 (82-92)SiO 2 II wherein M1 is a transition metal selected from Fe, Co, and Ni, M2 is a transition metal selected from Zn, Mn, Ga, and Sn, M is a transition metal selected from Fe, Co, Ni, Cu, Zn, Mo or Mn, and RE represents a rare earth metal; x is 1 or 2, when x is 1, the value of y is a half of the valence of the transition metal M1, and when x is 2, the value of y is the valence of the transition metal M1; m is 1 or 2, when m is 1, the value of n is a half of the valence of the transition metal M2, and when m is 2, the value of n is the valence of the transition metal M2; p is 1 or 2, when p is 1, the value of q is a half of the valence of the transition metal M, and when p is 2, the value of q is the valence of the transition metal M; the catalyst also contains an assistant catalytic component, which is one or more selected from the group consisting of Group IVB metals, non-noble metals in Group VIII, and rare earth metals of the Periodic Table of the Elements; based on the weight of the catalyst, said catalyst contains 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.
