COMMERCIAL TEST OF OLEFIN REDUCTION CATALYST AND NEW STANDARD GASOLINE PRODUCTION

To minimize air pollution, Beijing began to use new gasoline standard from July 1, 2000. To meet market need, the refinery of Beijing Yanshan Petrochemical Group Co. Ltd. performed the first commercial test of olefin reduction catalyst in 3# FCC unit. The test result shows that catalyst GOR-DQ can obviously reduce olefin content of FCC gasoline. With the test going on, olefin content in products decreased by 10%, little change in total liquid yield, but yield of gasoline and LCO slightly decreased, octane number, yields of LPG and coke increased. With FCC gesoline olefin reduction and the start up of CCR reforming unit, supply of qualified new standard gasoline has grown in this refinery.
