摘要
This article refers to the application of DOCO olefin-reducing catalyst developed by RIPP and manufactured by the Catalyst Factory of Changling Refining and Chemical Company in the 1.4 Mt/a RFCCU at Daqing Petrochemical Company. Results of operation over two months had revealed that this catalyst had good olefin-reducing ability and heavy oil converting ability adapted to paraffinic feedstock. The gasoline olefin yield had been reduced to 36.1 v% from 54.2 v% with gasoline RON rating decreased by 1.4 units. The induction period of gasoline had significantly increased to 952 mm, while the coke yield was increased by 0.05 percentage point with light oil yield dropping by only 0.02 percentage point. The FCC product distribution is favorable.
