摘　　要：近年来,在全球大力推进碳中和的背景之下,碳捕集、利用与封存(CCUS)技术的发展进入“快车道”。在整个CCUS产业链条中,碳捕集既是首要环节也是重要节点。常用的碳捕集方法有化学吸收法、膜分离法和物理吸附法等,其中化学吸收法被认为是目前最有市场应用前景的二氧化碳捕集技术,但高能耗与高成本限制了其大规模发展。目前化学吸收法的研究重点主要集中于吸收剂的优化,以降低能耗。对近年来报道的多种化学吸收剂进行了分析和总结,主要聚焦各类化学吸收剂的吸收性能、吸收机理、优缺点和增强途径等方面,并对其未来发展前景进行了展望,以对高效化学吸收剂的开发提供借鉴。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.
