摘　　要：考察了预还原处理对碳二(C2)前加氢催化剂性能的影响。结果表明,采用纯氢气氛下程序升温的方法对C2前加氢催化剂进行预还原处理,与未还原催化剂相比,当反应温度低于70℃时,前者的乙炔转化率高出约17个百分点,丙炔及丙二烯(MAPD)转化率高出约15个百分点,正丁烯生成量高出约100×10-6;但当反应温度高于70℃时,2种方法处理的催化剂性能相近。The effect of pre -reduction on the performance of C2 front - end hydrogenation catalyst was investigated. The results showed that below 70 ℃, the conversion of acetylene, methylacetylene and propadiene（MAPD） over C2 front -end hydro- genation catalyst pre -reduced in pure H2 by tem- perature programming process were nearly 17 and 15 percent points higher than those of unreduced one,the n - butene yield of the former was 100 × 10^-6 higher than that of the latter, and above 70 ℃ , both the catalysts were similar in their performance.
