Abstract: The industrial application data of imported G-58C catalyst and domestic LY-C2-02 catalyst in an ethylene unit in Lanzhou Petrochemical Company were analysed and compared，and the performance of LY-C2-02 catalyst was investigated. The new C2 hydrogenation catalyst LY-C2-02 was characterized by high activity，high selectivity，wide range of industrial application and high stability. It worked well when space velocity was 6000h-1, and its performance was as good as the G-58C catalyst. The LY-C2-02 catalyst could be used as the substitute of the imported G-58C catalyst. Industrial application of LY-C2-02 catalyst could help to reduce the cost of ethylene unit in China.

摘要： 在对进口G-58 C和国产LY-C2-02催化剂在兰州石化乙烯装置碳二加氢单元二段反应器的工业应用数据进行分析和比较的基础上，考察了改进型LY-C2-02催化剂的工业应用性能。结果表明：与G-58C催化剂相比，改进型LY-C2-02催化剂具有活性和选择性比较高、操作弹性范围宽、操作稳定等特点，完全适应6000 h－1空速的工艺条件，综合性能与G-58C催化剂水平相当；LY-C2-02催化剂具备替代进口G-58C型催化剂的能力，对实现碳二加氢催化剂国产化、降低乙烯装置成本、增加效益有一定的现实意义。
