摘　　要：采用常压微反、程序升温还原(TPR)、程序升温硫化(TPS)及原位红外光谱(IR)等技术,对Co Mo Al2O3催化剂的表征研究发现:在Co Mo Al2O3催化剂中不仅存在着Co、Mo中心,而且存在由Co、Mo相互作用产生的中心,Co Mo Al2O3催化剂的催化性能是由Co、Mo中心和Co、Mo相互作用产生的中心共同作用的结果。CoMo based catalysts can be widely used in petrochemical, coal based chemical and fertilizer industries Recently, many excellent CoMo based commercial catalysts have been exploited out by means of preparationprocess innovation, active components and/or additives adjustments and new type of support introduction In this paper, the features of CoMo based sulfurtolerant CO shift catalyst are characterized by using of MicroReactor, TemperatureProgrammed Reduction (TPR), TemperatureProgrammed Sulfurization (TPS) and insitu IR techniques It is found that there are two kinds of active sites on the CuMn/Al2O3 catalysts, one is Cu or Mn, and the other one is formed via their interaction The catalytic activity is contributed to both of the two kinds of the active sites
