摘　　要：CO_(2)捕集是实现碳中和的托底性技术。化学吸收法是最具商业化潜力的技术之一,而吸收过程中气液传质强化是影响CO_(2)捕集效率、能耗和成本的重要因素。针对新的气液传质强化模式,从微流体强化、引入额外能量场、引入第二相介质和微界面振荡技术全面总结和回顾了近年来的强化CO_(2)吸收手段和研究现状,重点关注微界面振荡技术的原理和研究方法,考察了不同强化手段的优劣势,为推动碳捕集过程中气液传质强化发展提供参考。Carbon dioxide(CO_(2))capture is a bottom-up technology for achieving carbon neutrality.Chemical absorption is one of the most promising technologies for commercialization,and the intensification of gas-liquid mass transfer in the absorption process is an important factor affecting the efficiency,energy consumption and cost of CO_(2)capture.For the new gas-liquid mass transfer intensification mode,the methods and research status of enhancing carbon dioxide absorption in recent years were summarized and reviewed from the aspects of microfluidic enhancement,introduction of additional energy field,introduction of the second-phase medium and micro-interfacial oscillation technology.The paper focused on the principle and research methodology of the micro-interfacial oscillation technology,and discussed the advantages and disadvantages of different enhancement means to provide reference for promoting the development of gas-liquid mass transfer enhancement in carbon capture process.
