A zeolite membrane reactor can be employed for hydrogenation of CO₂ to methanol. The removal of water from the reaction environment would increase the reaction rate and the achievable conversion. The separation of water from mixtures containing CO₂, hydrogen and water at suitable temperatures for this reaction was tested with several zeolite membranes (zeolite A, mordenite, zeolite T, chabazite and Ti-Chabazite). Zeolite A provided the best H₂O/H₂ separation factor. Preliminary experiments comparing a traditional reactor and the combination of a traditional reactor with a membrane reactor show that the yield of methanol was improved, in one case being higher than the limit corresponding to the thermodynamic equilibrium in a conventional reactor.

可以使用沸石膜反应器将CO ₂加氢为甲醇。从反应环境中除去水将增加反应速率和可达到的转化率。用几种沸石膜（沸石A，丝光沸石，沸石T，菱沸石和钛菱沸石）测试在适合于该反应的温度下从含有CO ₂，氢和水的混合物中分离水的能力。沸石A提供了最佳的H ₂ O / H ₂分离因子。初步实验比较了传统反应器和传统反应器与膜反应器的组合，结果表明甲醇的收率得到提高，在一种情况下，甲醇的收率高于常规反应器中对应于热力学平衡的极限。
