CATALYST AND METHOD OF CONVERTING ALIPHATIC C2-C12-HYDROCARBONS INTO HIGH- OCTANE GASOLINE OR CONCENTRATE OF AROMATIC HYDROCARBONS Russian patent published in 2001 - IPC

FIELD: gasoline production. SUBSTANCE: raw material is brought into contact with catalyst containing, wt %: pentasil-group zeolites with molar ratio h^-1 20-150, 40.0-80.0; zinc oxide, 0.5-4.0; iron oxide, 0.1-1.0; magnesium oxide, 0.1- 1.0; calcium oxide, 0.1-1.0; and binding agent, the balance. Contact is performed at temperature 280-600 C, pressure 0.5-3.0 MPa, and volumetric flow rate 0.5 to 10.0 SiO₂/Al₂O₃. EFFECT: increased yield of aromatic hydrocarbons from different-type starting materials. 2 cl, 2 tbl, 36 cl
