氨基酸离子液体促进的醇胺水溶液捕集CO2的研究进展

摘要

氨基酸离子液体（Amino acid ionic liquid，AAIL）可显著改善传统醇胺水溶液对CO2的吸收效果，但高粘特性限制了其在碳捕集工程中的应用。对AAIL促进醇胺水溶液吸收CO2的动力学及体系粘度的研究进展进行了综述，并分析了适宜烟气中CO2捕集的AAIL 醇胺吸收剂的遴选方法。%Amino acid ionic liquid (AAIL)is able to significantly promote the absorption of CO2 in amine aqueous solutions. However,its application in CO2 capture projects was limited due to the high viscosity characteristics. The advances in the absorption kinetics of CO2 in AAIL promoted amine aqueous solutions and the viscosity of the absorbents were reviewed. The approach for the determination of AAIL-amine absorbents applicable for CO2 remov-al from flue gas was analyzed.
