| 摘 要： | 用ＴＰＤ，ＴＰＳＲ－ＭＳ活性评价等方法，用Ｃｕ－Ｚｎ－Ａｌ催化剂，对ＣＯ２加氢合成甲醇的原料气掺入适量ＣＯ２进行了研究。结果表明ＣＯ２能占据催化剂表面部分ＣＯ２的吸附位，能抑制ＣＯ２加氢的逆水汽变换反应和促进甲醇合成，从而大大提高了ＣＯ２加事成甲醇的选择性和收率。

| Abstract: | The effects of CO on methanol synthesis from CO2 hydrogenation using Cu-Zn-Al as catalysts were studied by TPD,TPSR-MS techniques and catalytic per formance evaluation method. The results indicated that CO could occupy some of the CO2 adsorption sites on the catalyst surface, suppress the reverse water-gas shift reaction and promote methanol synthesis, therefore methanol selectivity with CO2 conversion increased obviously. |
