Ni催化剂上CO_2和CO的TPD及TPSR研究

STUDY ON TPD AND TPSR OF CO AND CO2 ON Ni CATALYSTS

在两种Ｎｉ催化剂上，用ＴＰＤ及ＴＰＳＲ技术研究了ＣＯ２及ＣＯ的脱附过程．结果表明，在催化剂Ｉ上存在两种活性中心，在催化剂Ⅱ上存在３种活性中心．

The desorption of CO and CO2 on the supported nickel catatysts was studied by TPD and TPSR.The results show that there are two kinds of active site on catalystⅠ and there are three kinds of active site on catalystⅡ.Activation energies Ed have been calculated and the reaction mechanism has been discussed.
