| Abstract: | CO2 has high solubility in ionic liquids, which makes ionic liquids widely used in fixation and conversion of CO2. Supercritical carbon dioxide extraction can be used to extract organics selectively from ionic liquids/ organics systems without cross-contamination, and then reuse the ionic liquids. The latest progress in experimental determination of CO2 solubility in ionic liquids, binary phase behavior of CO2 / ionic liquids systems under high pressure, ternary phase behavior of CO2 / ionic liquids / organics systems and modeling methods are reviewed. The future research of the technology are also analyzed. |
