原料气中CO对CO_2催化加氢合成甲醇的影响

Effect of CO in Raw Gas on Methanol Synthesis by CO2 Hydrogenation

用三种ＣＯ含量不同的原料气对Ｃｕ／Ｚｎ／Ａｌ／Ｚｒ四组份催化剂进行ＣＯ２加氢合成甲醇的研究。结果表明，原料气中掺入的ＣＯ能提高ＣＯ２加氢合成甲醇的选择性和收率。ＴＰＳＲ－ＭＳ谱说明预吸附的ＣＯ能抑制ＣＯ２加氢的逆水汽变换反应，而有利于转化为甲醇。

he effect of CO on CO2 hydrogenation over Cu/Zn/Al/Zr quaternary catalyst was studied.The result showed that when CO was added to the raw gas,the methanol selectivity and yield increased.TPSRMS spectra indicated that the preadsorption of CO on the catalyst could depress the reverse watergas shift reaction from CO2 hydrogenation,and thus be beneficial to the production of methanol.
