Abstract: Carbon dioxide(CO2) 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 CO2 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 incarbon capture process.

Key words: mass transfer, carbon dioxide capture, process enhancement, micro-interfacial oscillation
