摘要：Effects of operation conditions were studied oil the compositions and research octane number (RON) of gasoline front fluid catalytic cracking (FCC) with the GOR-Q catalyst and it normal MLC-500 catalyst for reducing olefin content. The results show that the effect of the GOR-Q catalyst oil decreasing the olefins content in FCC gasoline is obvious and most of olefins in gasoline have low carbon numbers. The influence of the operation conditions oil olefin, aromatics, and isoparaffin content of FCC gasoline is apparent. The Operation Conditions at a reaction temperature of < 520 degrees C and it catalyst/oil (cat/oil) ratio of no less than 7 for the GOR-Q catalyst are beneficial to reduce the olefin content of gasoline.]the RON value of FCC gasoline will decreased by 1.1-1.7 units, under a reaction temperature of 500-520 degrees C and the cat/oil ratio changes from 5 to 8.
