Zeolite-containing hydrocarbon-converting catalyst, the preparation process thereof, and a process for converting hydrocarbon oils with the catalyst

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, and said macroporous zeolite is one or more selected from the group consisting of faujasite, zeolite-L, zeolite-β, zeolite-Ω, mordenite, and ZSM-18 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:
• (0-0.3)Na2O.(0.3-5.5)Al2O3.(1.0-10)P2O5.(0.7-15)M1XOy.(0.01-5)M2mOn.(0-10)RE2O3.(70-97)SiO2 I
• and
• (0-0.3)Na2O.(0.3-5)Al2O3.(1.0-10)P2O5.(0.7-15)MpOq.(0-10)RE2O3.(70-98)SiO2 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.
