摘要

介绍了负载离子液体膜(SILMs)分离co2 / n2的方法。用1-乙基-3-甲基咪唑醋酸酯([Emim][Ac])浸渍商业PDMS(聚二甲基硅氧烷)膜和商业微滤膜(Inopor)的陶瓷支撑纳米孔，开发了silm。在相同的陶瓷载体上制备的silm的分离效率比较表明，基于PDMS膜的silm具有良好的稳定性和很高的CO 2 /N 2选择性。他的研究结果提供了一种廉价的方法来选择性地分离CO 2 /N 2，特别是当选择性的选择是第一优先考虑的时候。与Robeson上键相关和文献数据的对比表明，离子液体和适当的浸渍方法对PDMS膜的分离性能有显著提高。

CO2/N2 Separation by Supported Ionic Liquid Membranes Based on Tubular Ceramic Support Impregnated with Selected Ionic Liquid

The separation of CO 2 /N 2 by supported ionic liquid membranes (SILMs) is presented. SILMs have been developed by impregnation of the ceramic support nanopores of commercial PDMS (polidimethylosiloxane) membranes (made by Pervatech BV) and commercial microfiltration membranes (made by Inopor) with 1-ethyl-3-methylimidazolium acetate ([Emim][Ac]). Comparison of separation efficiency of SILMs prepared on the same ceramic support shows that SILMs based on PDMS membranes show good stability and very high CO 2 /N 2 selectivity. Yhe obtained results present an inexpensive alternative in selective CO 2 /N 2 separation by SILMs, especially when the choice of selectivity is the first priority. The comparison with Robeson upper bond correlation and literature data shows that applying the ionic liquid and appropriate impregnating method to the PDMS membranes results in significant improvement of separation performance.
