摘　　要：醇胺法是工业上成熟的CO2吸收技术,但醇胺吸收剂存在易氧化降解、能耗高及环境危害较大等问题,因此人们对新型绿色、低能耗二氧化碳吸收剂的探索研究日益活跃。氨基酸盐具有抗氧化性强、非挥发性、环境危害小等特点。本文综述了近十年来氨基酸盐吸收剂研究概况,着重介绍了氨基酸盐结构、物性、反应动力学及反应机理的研究情况。The absorption of CO2 by alkanolamines is a mature technology in industrial processes, but due to problems associated with alkanolamines, such as their degradation in oxygen rich atmospheres, considerable energy need for solvent regeneration and negative environmental impacts, the quest to find alternative candidates is of outstanding necessity. The various positive properties of amino acid based solvents including a higher resistance to degradation, low volatility, and little negative environmental impacts encourage the researchers to work more on these solvents for commercial implementation. This review first introduces the structure of amino acid salts, and then summarizes physicochemical properties of amino acid salts, kinetics of CO2 absorption and reaction mechanism in aqueous amino acid salt solutions.
