摘　　要：铜系CO低温变换催化剂的还原条件对催化剂的使用效果产生很大的影响,其中还原气中氢的浓度是一个关键的因素。介绍了在不同的氢浓度条件下,低温变换催化剂还原时的操作及其使用效果,提出了采用低氢、低温还原工艺对催化剂进行还原,可以使催化剂使用寿命延长2年以上,直接减少催化剂消耗费用40万元。The reducing condition of CO LT shift copper catalyst has a great impact on the application effect of the catalyst,among which hydrogen gas concentration in reducing gas is a key factor. This paper introduces reduction operation and application effect of LT CO shift catalyst under various hydrogen concentrations,and proposes to apply low hydrogen and low temperature reduction process for catalyst reduction,which can prolong the service life of the catalyst for more than 2 years and decrease 400 000 RMB catalyst consumption.
