摘　　要：CO_(2)捕集、利用与封存技术是实现“碳中和”的一种有效解决方案,发展高技术经济性的强化吸收方法是碳捕集的基础。由于单胺溶液的局限性,基于耦合策略的多元复配溶剂强化吸收CO_(2),尤其是能源利用过程中排放的CO_(2),能够实现官能团的相互协同、增强吸收性能和降低再生能耗。该文论述了基于乙醇胺(MEA)的最新多元复配、无水、离子液体和相变吸收剂复配溶剂强化吸收CO_(2)的性能特性和过程机理,分析了CO_(2)分压、温度、溶剂质量分数、气液流速对吸收性能的定量影响,并对其技术经济性能进行了分析。最后,对基于MEA的多元复配溶剂吸收CO_(2)发展过程中尚需解决的问题进行了总结,并对未来的发展方向进行了展望。CO_(2)capture,utilization and sequestration technology is an effective solution to achieve"carbon neutralization",and the development of enhanced absorption method with high-tech and cost-efficacy is a prerequisite for carbon capture.Due to the limitation of monoamine solution,the multi-component solvents based on coupling strategy can enhance the absorption of CO_(2),especially the CO_(2)emitted during the energy utilization process,which can achieve the coordination of functional groups,enhance the absorption performance and reduce the energy consumption of regeneration.In this review,the performance characteristics and process mechanism of enhanced CO_(2)absorption by the latest multicomponent complex solvents based on monoethanolamine(MEA),such as mcllticompcment complex,anhydrous,ionic liquid and phase change absorbents were discussed.The quantitative effects of important operating parameters such as CO_(2)partial pressure,temperature,mass fraction of solvent and gas-liquid flow rate on the absorption performance were evaluated,and its technical and economic properties were analyzed.Finally,the problems to be addressed in the development of CO_(2)absorption by multi-component mixed solvents based on MEA were summarized and the future development direction was prospected.
