采用高压膜反应器进行甲醇合成反应。将合成气进料到MR壳侧，其中使用商业MeS催化剂，而管侧用对甲醇具有良好溶解度的高沸点液体吹扫。采用介孔氧化铝陶瓷膜，其表面经过改性，使其更疏水。在各种实验条件（不同的压力、温度、扫掠液体流速和扫掠液体类型）下研究MR的效率。结果表明，与传统的填充床反应器相比，改进的每单程碳转化率。离子液体（IL），1-乙基-3-甲基咪唑四氟硼酸盐，在MR中用作扫描液体。实验结果与我们小组以前报道的结果进行了比较（Li，Z.; Tsotsis，T. 2019，570，103），同时使用常规石油衍生溶剂四乙二醇二甲醚（TGDE）作为吹扫液体。使用IL获得了增强的碳转化率（在石油衍生的溶剂上）。
In this study, a high-pressure membrane reactor (MR) was employed to carry out the methanol synthesis (MeS) reaction. Syngas was fed into the MR shell side where a commercial MeS catalyst was used, while the tube side was swept with a high boiling point liquid with good solubility toward methanol. A mesoporous alumina ceramic membrane was utilized after its surface had been modified to be rendered more hydrophobic. The efficiency of the MR was investigated under a variety of experimental conditions (different pressures, temperatures, sweep liquid flow rates, and types of sweep liquids). The results reveal improved per single-pass carbon conversions when compared to the conventional packed-bed reactor. An ionic liquid (IL), 1-ethyl-3-methylimidazolium tetrafluoroborate, was utilized in the MR as the sweep liquid. The experimental results are compared to those previously reported by our group (Li, Z.; Tsotsis, T. T.J. Membrane Sci.2019, 570, 103) while using a conventional petroleum-derived solvent as sweep liquid, tetraethylene glycol dimethyl ether (TGDE). Enhanced carbon conversion (over the petroleum-derived solvent) was obtained using the IL.
