In recent years,under the background of global efforts to promote carbon neutrality,the development of carbon capture,utilization and storage(CCUS)technology has entered the"fast lane".In the whole CCUS industry chain,carbon capture is both the first link and an important node.The commonly used carbon capture methods include chemical absorption method,membrane separation method and physical adsorption method,among which chemical absorption method is considered to be the most promising carbon dioxide capture technology at present,but high energy consumption and high cost limit its large-scale development.At present,the research of chemical absorption method mainly focuses on the optimization of absorbents to reduce energy consumption.Various chemical absorbents that have been reported in recent years were analyzed and summarized,mainly focusing on the absorption performance,absorption mechanism,advantages and disadvantages,and enhancement pathways,and their future development prospects were prospected,so as to provide reference for the development of high efficiency chemical absorbents.
