摘　　要：国内新建前加氢装置较多引进了进口催化剂,部分催化剂出现了操作窗口较窄的情况,漏炔事故时有报道。本文以准工业模式制备催化剂,采用侧线规模进行性能考核实验,实验以前脱乙烷前加氢为研究对象,采用调整脱炔负荷的方式,考察催化剂在末段床的脱炔能力。实验结果表明,采用该催化剂可以稳定脱除乙炔,无漏炔和飞温趋势,乙烯选择性合理,有利于避免漏炔事故。There are many new C2-front end hydrogenation processes in China,imported catalysts are introduced,and acetylene leakage accidents have been reported. In this paper,the catalyst was prepared in a quasiindustrial mode,and the performance of the catalyst was tested on the side-line scale. The experimental results show that the catalyst can remove acetylene stably,without the tendency of acetylene leakage and fly temperature,and the selectivity of ethylene is reasonable,which is helpful to avoid acetylene leakage.
