The improved LY-C2-02 catalyst was prepared by taking into account the characteristics of Fushun ethylene C2 hydrogenation unit. The running performance of the improved LY-C2-02 catalyst was investigated by comparing with G-58C catalyst. The experiment was performed in a simulating equipment for 12 days,and the catalyst was run in two reactors in series. The results showed that the acetylene decrease was 1.0% in the first reactor,which was 0.04% higher than G-58C catalyst; the selectivity was 81.5% in the second reactor,which was 3.5% higher than G-58C catalyst. The comprehensive performance of improved LY-C2-02 catalyst achieved the performance of G-58C catalyst. It indicated that the improved LY-C2-02 catalyst satisfied the technical demand of the first and second reactors of Fushun ethylene C2 hydrogenation unit.
