Study on Hydrotreating Technology of FCC Gasoline

HDS/olefin reducing can remove sulfur and saturate olefin,at the same time,gasoline octane number has less change.In this paper,hydrotreatment of FCC gasoline with combined process of HDDO-01 catalyst and HDDO-02 catalyst was introduced,sulfur content reached 50 μg / g below,the loss of gasoline octane number was less than 2.
