Abstract

Under the background of “carbon peaking and carbon neutrality” goals

the development of liquid-liquid phase-change absorbents is of great significance for the development of CO

capture technologies with low energy consumption and high operational stability. Focusing on the mechanisms of liquid-liquid phase-change absorbents

the phase separation behaviors during the CO

absorption process were summarized. It was pointed out that the compositions of the system and the intermolecular interactions were closely related to the phase change behaviors. On this basis

recent research advances of liquid-liquid phase-change absorbents were reviewed from two key aspects

namely the reduction of regeneration energy consumption and the regulation of rich-phase viscosity. Furthermore

the major challenges hindering their industrial application

including insufficient phase separation stability

oxidative and thermal degradation and equipment corrosion

were systematically analyzed. To address these challenges

feasible optimization strategies

such as molecular structure design

solvent system optimization and functional additive regulation

were discussed. Finally

future development directions of liquid-liquid phase-change absorbents were prospected.
