摘　　要：降低FCC汽油烯烃含量的关键是要增加FCC反应中的氢转移能力,以饱和汽油中的烯烃。由石油化工科学研究院和兰州石化公司催化剂厂合作开发的LGO 20、LGO 21系列降烯烃重油裂化催化剂和LGO A降烯烃助剂,适用于降低汽油烯烃含量,可根据装置特点及目的产品要求灵活调变活性组分及其配比,并通过不同的基质改性技术生产具有针对性的产品,该系列催化剂普遍具有显著的降低催化汽油烯烃的性能,在装置维持掺渣量较高(约65%～70%)的条件下,通过调整工艺操作条件,可以将催化汽油中烯烃含量降低10～15个百分点,使汽油烯烃控制在40vol%左右,RON在90以上。LGO 21更具有提高柴油产率的性能。The key to reducing olefin content in FCC gasoline is to increase the hydrogen transfer capability in FCC reaction to saturate the olefin in gasoline. A series of olefin reducing RFCC catalysts (LGO20, LGO21) and promoter (LGOA) were jointly developed by the Research Institute of Petroleum Processing (RIPP) and PetroChina Lanzhou Petrochemical Corporation (LPCC). The active components and their proportion are adjustable according to characteristics of the unit and target products. By adjusting process condition, olefin content in RFCC gasoline can be reduced by 10-15% and controlled around 40% and RON above 90 while maintaining high residual oil load (about 65%-70%) in the feed. LGO21 catalyst can meanwhile increase diesel yield.
