PRODUCTION OF GASOLINE HAVING HIGH OCTANE VALUE

摘要

PURPOSE:To obtain high-octane gasoline in high yield, by contacting a light hydrocarbon with a catalyst containing zinc, manganese and crystalline aluminosilicate. CONSTITUTION:A high-octane gasoline having a research octane number of >=95 is produced by contacting a light hydrocarbon composed mainly of 2-7C paraffins and/or olefins with a crystalline aluminosilicate containing zinc and manganese and having a molar ratio of silica/alumina of 2-100 (preferably ZSM-5 zeolite) at 350-650 deg.C under a hydrogen partial pressure of <=5kg/cm<2>.
