液-液相变溶剂捕集CO_2烟气技术的研究进展

Research progress in CO_2 flue gas capture technology using liquid-liquid phase-separation solvents

化学溶剂吸收法是目前最有效的CO_2烟气捕集技术,但过高的再生能耗是限制工业应用的瓶颈。本文综述了常规化学吸收溶剂吸收CO_2的反应机理,并介绍了化学吸收技术的捕集工艺及目前发展现状。重点阐述新型吸收溶剂液-液相变溶剂在CO_2烟气捕集方面的研究进展,并对液-液相变吸收技术发展前景进行了展望。

Chemical solvent absorption is the most effective CO2 gas capture technology, but high regeneration energy consumption is a bottleneck that limits industrial applications. In this paper, the mechanism of the absorption of CO2 by conventional chemical absorption solvents is reviewed,the capture process and the current development statusof chemical absorption technology are introduced. This paper focuses on the research progress of new solvent-assisted solvent liquid-liquid phase-change solvents in CO2 flue gas capture, and looks into the development prospects of liquid-liquid phase-separation absorption technologies.
