摘要

化学溶剂吸收法是最有应用潜力的燃烧后二氧化碳脱除技术之一，较高的溶剂再生能耗阻碍了其进一步的工业应用。液-液相变溶剂由于具有降低吸收再生能耗的潜力，成为新型吸收剂的研究热点。综述了液-液相变溶剂的研究现状，从溶剂组成及其相变机理角度出发，将液-液相变溶剂分为热致相变溶剂、有机胺-低吸收速率胺溶剂、化学-物理溶剂、有机胺-离子液体溶剂四类吸收剂，分别介绍各类溶剂的研究进展，重点阐述其吸收性能及相变机理，并分析比较了各溶剂的优缺点。分析表明液-液相变溶剂节能潜力较大，今后的研究工作应侧重于相变溶剂的设计原则及分层机理的深入探讨。

Abstract

Chemical absorption is one of the most promising technologies for post-combustion CO2 capture. But the high energy consumption of solvent regeneration process will limit its further development. The liquid-liquid biphasic solvents have been widely concerned by researchers due to the potential of reducing the energy consumption of CO2 desorption process. This paper gives an overview of the development of liquid-liquid biphasic solvents. According to the solvents composition and the phase separation mechanism

the liquid-liquid biphasic solvents are divided into thermomorphic biphasic solvents

organic amine-low absorption rate amine solvents

chemical-physical solvents

and organic amine-ionic liquid solvents. The research progress of various solvents is introduced

including the absorption performance and the phase separation mechanism. The advantages and disadvantages of the solvents are analyzed. It can be concluded that liquid-liquid biphasic solvents have great potential for energy saving. The future research should focus on the design principle and the deep phase separation mechanism of liquid-liquid biphasic solvents.
