中文摘要：

离子液体具有蒸汽压极低、热稳定性好、热容低和可以根据目标需求进行设计等特性,能克服传统CO2捕集工艺的诸多不足,因而成为目前CO2捕集溶剂的研究热点。本文主要综述了普通离子液体、功能化离子液体、支撑型离子液体膜、聚合型离子液体和离子液体复配溶液在CO2捕集方面的应用研究进展,评述了各种方法的优势和缺点,并在此基础上提出了离子液体用于CO2捕集需要解决的问题和应用前景。

英文摘要：

Room-temperature ionic liquids（RTILs） are emerging as promising media rivaling with conventional process for CO2 capture and separation because of their advantages including negligible vapor pressure,reasonable thermal stability,low thermal capacity and flexibility in synthetic structure.The progress of the application of the ordinary ionic liquids（ILs）,task-specified ionic liquids（TSILs）,supported ionic liquid membranes（SILMs）,polymerized ionic liquids（PILs） and ionic liquids-based solutions in capturing CO2 from fuel gases was summarized,and their utilization in the future and problems existed were put forward.
