Economical and environmental concerns are the main motivations for development of energy-efficient processes and new eco-friendly materials for the capture of greenhouse gases. Currently, HS capture is dominated by physical and/or chemical absorption technologies, which are, however, energy intensive and often problematic from an environmental point of view due to emission of volatile solvent components. Ionic liquids have been proposed as a promising alternative to conventional solvents because of their low volatility and other interesting properties. The aim of the present review paper is to provide a detailed overview of the achievements and difficulties that have been encountered in finding suitable ionic liquids for HS capture. The effect of ionic liquid anions, cations, and functional groups on the HS absorption, separation, and oxidation are highlighted. Recent developments on yet scarcely available molecular simulations and on the development of robust predictive methods are also discussed.
经济和环境方面的考虑是开发节能工艺和新型环保材料以捕获温室气体的主要动力。目前，HS 的捕获主要依赖于物理和/或化学吸收技术，但这些技术是能源密集型的，并且由于挥发性溶剂成分的排放，从环境角度来看往往存在问题。离子液体由于其挥发性低和其他有趣的性质，已被提议作为传统溶剂的一种有前途的替代品。本文综述的目的是详细概述在寻找适合 HS 捕获的离子液体方面所取得的成就和遇到的困难。重点介绍了离子液体阴离子、阳离子和官能团对 HS 吸收、分离和氧化的影响。还讨论了在分子模拟方面的最新进展以及开发稳健的预测方法。
