二氧化碳加氫合成甲醇与一氧化碳加氫合成甲醇的反应是有一些不同的。一氧化碳加氫合成甲醇是工业上常用的方法,共反应如下所示: CO+2H_2→CH_3OH+△H △H=-21630 卡/克分子工业上采用的催化剂大都为Zn-Cr系的催化剂,其組成約为:ZnO67％,Cr_2O_316％,CrO_310％。二氧化碳加氫合成甲醇的反应,一般說法,按二步进行,其反应可以表示如下: The reaction of hydrogenation of methanol to methanol and hydrogenation of carbon monoxide to methanol is somewhat different. Hydrogenation of carbon monoxide to methanol synthesis is commonly used in industry methods, the total reaction is as follows: CO + 2H_2 → CH_3OH + △ H △ H = -21630 cards / mol Molecule Most of the industrially used catalysts are Zn-Cr-based catalysts, the composition About: ZnO67%, Cr20316%, CrO310%. The reaction of hydrogenation of methanol to methanol synthesis, the general statement, according to two steps, the reaction can be expressed as follows:
