ZEOLITE-CONTAINING CATALYST AND METHOD OF CONVERTING $$$-HYDROCARBONS INTO HIGH-ANTIKNOCK GASOLINE COMPONENT OR AROMATIC HYDROCARBON CONCENTRATE Russian patent published in 1997 - IPC

FIELD: CATALYSTS FOR PETROCHEMICAL PROCESSES. SUBSTANCE: catalyst contains, wt. -%: pentasil-type zeolite with silicate modulus $$$ = 20-80 and residual sodium oxide content not exceeding 0.2 wt %, 50-75; zinc oxides, 0.5-3; rare-earth metal oxides, 0.5-3; phosphorus pentoxide, 0.5-2; and binding component, the balance. Alifatic $$$-hydrocarbon are converted into high-antiknock motor gasoline with octane number not below 76 points (motor method) or into aromatic hydrocarbon concentrate at 280-550 C, pressure 0.2- 2.0 MPa, raw material supply volume rate 0.5-5.0 $$$. EFFECT: enlarged resource of quality gasoline components. 2 cl, 5 tbl
