摘　　要：裂解汽油C_(8+)馏分是乙烯装置的主要副产品之一。其中分离出的C_(9)馏分组成极其复杂,含有许多带有双键的活性组分,溴价、碘值及胶质较高,给后续利用带来困难。主要阐述了SL-C9-04IA/SL-C9-04IB型催化剂在裂解C_(9+)预加氢装置上的工业应用,简要分析了裂解C_(9)重馏分掺配双环戊二烯后对催化剂运行的影响,为C_(9)馏分的加氢提供了新方向、新选择,助力提高C_(9)产品的附加值。C8+fraction of pyrolysis gasoline is one of the main by-products of ethylene plant.The separated C_(9) fraction has very complex composition and contains many active components with double bonds.Its bromine value,iodine value and colloid content are high,which brings difficulties to subsequent utilization.The commercial application of SL-C9-04IASSL-C9-04IB type catalyst in the pre-hydrogenation unit of cracking C_(9+)was described.The influence of blending dicyclopentadiene of heavy fractions of cracking C_(9) on the operation of the catalyst was briefly analyzed,providing a new direction and choice for the hydrogenation of C_(9) fraction and helping to increase the added value of C_(9) product.
