METHOD FOR REFINING BENZINE Russian patent published in 1995 - IPC

Abstract RU 2049806 C1

FIELD: oil processing and oil refining industry. SUBSTANCE: benzine is refined at elevated temperature and pressure, 200-400 C and 0.1-1 MPa being preferred. The process is carried out on aluminosilicate zeolite-containing catalyst, content of said zeolite is 0.5-5 mass molar ratio of silicium oxide and aluminium oxide in said zeolite being 25-90. Mentioned above catalyst contains (mass ): aluminium oxide 0.5-7.5, sodium oxide 0.05-0.5, silicium oxide the rest; or aluminium oxide 0.5-7.5, zinc oxide 0.05-2.5, sodium oxide 0.05-0.5, silicium oxide the rest; or aluminium oxide 0.5-7.5, gallium oxide 0.05-2.5, sodium oxide 0.05-0.5, silicium oxide the rest. EFFECT: improves efficiency of method. 2 cl, 1 tbl
