【Abstract】 Based on the mechanism of hydrogen transfer reaction, influence of catalyst pore structure, Si /Al ratio, rare earth element concentration, crystal grain size, interaction of zeolites with matrix and the zeolites composition on FCC catalyst hydrogen transfer reaction activity are described. It is pointed that olefin content in FCC gasoline can be reduced by the improvement of catalyst manufacture and the selection of proper operation conditions and the catalyst with suitable hydrogen transfer activity. FCC gasoline octane number is not decreased and the coking can be inhibited.更多还原
