Abstract: Catalyst for C2 front-end hydrogenation was prepared via equality design methodology，and the composition and preparation technics were optimized. The prepared catalyst was compared with the commercially available catalyst in a simulating industry unit for 1000 h. It was proved that the activity of the prepared catalyst is slightly lower than that of the commercial one，while the prepared catalyst has a better selectivity. XPS analysis revealed that the prepared catalyst has a stronger effect with Pd-Ag alloy，and XRF analysis illustrated that the prepared catalyst has a less active composition on the catalyst surface.

摘要： 采用均匀设计方法，进行了碳二前加氢催化剂的制备，确定了催化剂的最佳配方和制备工艺。1000 h工业侧线对比评价结果表明，自制催化剂活性稍低于市售催化剂，选择性高于市售催化剂，两种催化剂总体性能相当。X光电子能谱分析表明，自制催化剂钯银合金作用更为明显，X荧光光谱分析表明表面活性组分含量低于市售催化剂。
