Abstract

RFG-DMR olefin reducing catalyst in the heavy oil FCCU of Dongming Petrochemical Group was expounded. Evaluation result showed that the catalyst decreasing olefin content in gasoline was ideal after RFG-DMR in the system catalyst inventory reached 83%. The olefin content in gasoline dropped from 48.56% to 39.72%,decreased by 8.84 percentage. Gasoline Octane Number didn't decrease, however, the product slate was reasonable. The catalyst had a strong ability for residuum conversion, furthermore, the catalyst had the advantages of good dry gas and coke selectivity. The total liquid yield had been increased by 1.56 percentage with a light oil yield increased by 1.07 percentage.
