The commercial application experiments on this promoter were conducted in the #3 RFCCU at Dalian Petrochemical Co. and #1 integrated refining unit at Shanghai Petro- chemical Co. The test results have shown that after adding 5%—6% of the promoter LCC-A to the main FCC catalyst the propylene yield and selectivity were raised obviously. The octane rating of FCC gasoline was increased by more than one unit; which could alleviate the negative impact of octane number decline resulted from reduction of olefin content in FCC naphtha along with an increased propylene yield to meet the urgent market demand for propylene. The test results achieved at Shanghai Petrochemical Company have revealed that when the addition of the LCC-A promoter reached 5% of the catalyst inventory, its performance could be on a par with that of the overseas promoter OlefinsMax.展开更多
