摘　　要：以燃煤发电为主的基础能源电力行业是煤消耗大户和大型的CO_(2)固定排放源,通过捕集系统减少燃煤电厂CO_(2)排放是实现我国碳达峰和碳中和减排目标的重要途径之一。膜气吸收分离CO_(2)工艺同时具备了化学吸收法的高选择性和膜分离工艺结构紧凑的特点,是一种有望代替传统燃煤电厂烟气低浓度CO_(2)的分离方法。概述了膜气吸收法分离CO_(2)的主要工作原理,重点从吸收剂选择、膜材料分类、膜-溶剂交互作用机理和系统长周期运行稳定性4个方面介绍中空纤维膜接触器分离燃煤电厂烟气中CO_(2)的研究进展,最后对中空纤维膜接触器分离烟气CO_(2)工艺的发展趋势和应用挑战进行了展望。Fundamental energy power industry mainly depending on coal-fired power generation is a large coal consumer and a large-scale fixed source of CO_(2) emissions.Reducing CO_(2) emissions from coal-fired power plants through CO_(2) post-combustion capture systems is one of the important approaches to achieve China s carbon peak and carbon neutral goals.Membrane gas absorption technology combines the advantages of chemical absorption(high selectivity)and membrane separation(compact structure),which is a promising method to replace traditional separation methods of CO_(2) from the flue gas of coal-fired power plants.This study first introduces the working principle of CO_(2) separation by membrane gas absorption method.Then the study presents the CO_(2) separation by hollow fiber membrane contactor from flue gas of coal-fired power plants mainly from four perspectives,including absorbent selection,membrane material,membrane-solvent interaction mechanism and long-term operation stability.Finally,the development trend and application challenges of the hollow fiber membrane contactor technology for CO_(2) separation from flue gas CO_(2) are prospected.
