摘　　要：页岩气作为新型的清洁低碳能源迅速引起各国的高度重视,因此页岩气中CO2的吸收就尤为重要。离子液体因挥发性低、溶解能力强、结构和性质可调控性强等特点,在气体净化方面获得高度关注。本文系统地总结了离子液体吸收CO2的研究,包括常规离子液体、功能化离子液体、聚合物离子液体;讨论了离子液体结构等因素对吸收性能的影响;对各方法的优缺点及使用条件进行详细的阐述;并提出今后离子液体在页岩气中CO2气体净化方面的发展方向。Shale gas sweetening, especially CO2 cleaning, is an important prerequisite in many different applications and industrial areas for meeting increased environmental requirements. Ionic liquids as green solvents have attracted great attention due to the unique properties. As a result, ionic liquids are emerging as promising candidates rivaling with conventional amine scrubbing. This brief review presented a survey of the most recent development in ionic liquids for CO2 absorption. All kinds of ionic liquids, e. g. , conventional ionic liquids, task-specific ionic liquids and polymeric ionic liquids were reviewed. The future developments of ionic liquids for CO2 absorption were suggested aiming to expand these ILs to large scale processes.
