Ionic liquids (ILs) are efficient solvents for the selective removal of CO2 from flue gas. Conventional, offthe-shelf ILs are limited in use to physisorption, which restricts their absorption capacity. After adding a chemical functionality like amines or alcohols, absorption of CO2 occurs mainly by chemisorption. This greatly enhances CO2 absorption and makes ILs suitable for potential industrial applications. By carefully choosing the anion and the cation of the IL, equimolar absorption of CO2 is possible. This paper reviews the current state of the art of CO2 capture by ILs and presents the current research in this field performed at the ChemTech Institute of the Ecole d'Ingénieurs et d'Architectes de Fribourg.
离子液体（ILs）是用于从烟道气中选择性去除二氧化碳的高效溶剂。传统的现成离子液体仅限于物理吸附使用，这限制了它们的吸收能力。添加胺或醇等化学官能团后，二氧化碳的吸收主要通过化学吸附发生。这大大提高了二氧化碳的吸收能力，使离子液体适用于潜在的工业应用。通过仔细选择离子液体的阴离子和阳离子，可以实现等摩尔的二氧化碳吸收。本文综述了离子液体捕获二氧化碳的当前技术水平，并介绍了弗里堡工程师与建筑师学院化学技术研究所目前在该领域开展的研究。
