在ＣＯ２加氢合成甲醇的原料气中，掺入适量的ＣＯ，能相对提高ＣＯ２加氢合成甲醇的选择性和产率．它们分别为１３２％和３８％．ＴＰＤ和ＴＰＳＲ－ＭＳ实验表明，ＣＯ能占据催化剂表面部分的活性位，并抑制ＣＯ２的逆水汽变换反应，从而促进甲醇的合成 In the CO2 hydrogenation of methanol feed gas, the incorporation of the appropriate amount of CO, can relatively increase the selectivity and yield of methanol by CO2 hydrogenation. They are 132% and 38% respectively. TPD and TPSR-MS experiments show that CO can occupy the active site on the surface of the catalyst and inhibit the counter-water vapor shift reaction of CO2, thus promoting the synthesis of methanol
