面向碳捕集的液-固相变吸收剂的研究进展

Research progress of liquid solid phase transition absorbers for carbon capture

人类工业活动排放的大量CO_(2)气体是导致全球变暖的主要因素,CO_(2)捕集、封存与利用(CCUS)是实现碳减排和应对全球变暖最有效的技术方向。目前,工业上多采用的醇胺法捕集CO_(2)存在解吸能耗高的问题,寻找低能耗的碳捕集方法成为目前研究的重点。基于相变吸收剂的碳捕集过程所需的再生能耗较传统的醇胺法大大降低,被认为是理想的替代方法。综述了CO_(2)液-固相变吸收剂的研究现状,探索了液-固相变吸收剂的相变机理,并对液-固相变溶剂的研究动向和技术发展前景进行了展望。

A large amount of CO_(2)gas emitted by human industrial activities is the main factor leading to global warming.CO_(2)capture,storage and utilization(CCUS)are the most effective technical direction to achieve carbon emission reduction and respond to global warming.At present,the widely used alcohol-amine method in industry to capture CO_(2)has the problem of high energy consumption for desorption.Therefore,finding low-energy carbon capture methods has become the focus of current research.Compared with the traditional alcohol-amine method,the regeneration energy consumption required for the carbon capture process based on phase transition absorber is greatly reduced,and it is considered as an ideal alternative method.In this paper,the research status of liquid-solid phase transition absorber for CO_(2)capture was reviewed,the phase transition mechanism of liquid-solid phase transition absorbents was explored,and the research trend and technological development prospect of liquid-solid phase transition solvents were prospected.
