CATALYST FOR CONVERTING ALIPHATIC C-C-HYDROCARBONS, METHOD FOR PREPARATION THEREOF, AND A METHOD FOR CONVERTING ALIPHATIC C-C-HYDROCARBONS INTO HIGH ANTIKNOCK GASOLINE AND/OR AROMATIC HYDROCARBONS Russian patent published in 2004 - IPC

FIELD: petroleum processing and petrochemistry.

SUBSTANCE: proposed catalyst contains 60.0-80.0% of iron-aluminosilicate with h-silica ZSM-5 zeolite structure having silicate module SiO₂/Al₂O₃ = 20-160 and ratio SiO₂/Fe₂O₃ = 30-5000; 0.1-10.0% of modifying additive selected from at least group of oxides: copper, zinc, gallium, lanthanum, molybdenum, and rhenium oxides; 0.5-5.0% of strengthening additive: boron oxide or phosphorus oxide, or mixtures thereof; and balancing amount of alumina binder. Catalyst is prepared by dry mixing of initial compounds followed by mechanochemical treatment on vibrating mill for 0.1 to 72 h, molding of catalyst paste, drying, and heat treatment at 550-600^оС during 0.1 to 24 h. Catalytic conversion of aliphatic C₂-C₁₂-hydrocarbons is carried out at 300-550^оС at volumetric flow rate 0.5 to 5.0 h^-1 and pressure from 0.1 to 1.5 MPa.

EFFECT: increased activity and selectivity of catalyst and considerably increased yield of antiknock gasoline and/or aromatic hydrocarbons.
