摘　　要：碳捕集、利用与封存(CCUS)是当今国际社会公认的实现碳减排和应对全球变暖最有效的方法。其中,有机胺法是碳捕集技术工业应用中最广泛的,但存在再生能耗高的问题。介绍了采用相变吸收剂的新型碳捕集技术,通过降低吸收剂中水的蒸发潜热以及吸收剂的升温显热来实现节能降耗。综述了CO2相变吸收剂在分相机理、分相形式等方面的研究现状和进展,并对目前研究过程中存在的问题以及未来的研发方向和前景进行了展望。Carbon capture,utilization and storage(CCUS)is the most effective way to reduce carbon emissions and deal with global warming.Organic amine method is the most widely used in carbon capture technology,but it has the problem of high energy consumption.As a new type of carbon capture technology,phase change absorbents have great advantages in reducing energy consumption,which can be realized by reducing the latent heat of water evaporation and sensible heat of temperature rise of absorbent.The research status and progress of phase separation mechanism and phase separation forms of CO2 phase change absorbents are reviewed.Also,the existing problems in the current research process and the future research direction are prospected.
