CO、CO_2、H_2直接合成二甲醚与甲醇的化学平衡

Chemical Equilibrium for Direct Synthesis of Dimethyl Ether and Methanol from CO、CO_2、H_2

由CO、CO_2、H_2直接合成二甲醚与甲醇为一复合反应体系，本文分别对CO加H_2、CO_2加H_2、合成气（即CO、CO_2同时加H_2）直接合成二甲醚与甲醇的化学平衡进行了计算，合成反应的单程转化率受到化学平衡的限制。

The direct synthesis of dimethyl ether and methanol from CO、CO_2、H_2 is a compound reaction system.Thermodynamic calculation is carried out respectively to the synthesis of dimethyl ether and methanol from (CO + H_2),(CO_2 + H_2 ) and (CO + CO_2 + H_2 ). The per pass conversion of the synthesis reaction is limited by chemical equilibrium.
