Ionic liquids/deep eutectic solvents for CO2 capture: Reviewing and evaluating

Abstract The CO2 solubilities (including Henry's constant) in physical- and chemical-based ILs/DESs the COSMO-RS models describing these properties were comprehensively collected summarized. summarized results indicate that are superior to physical-based for capture, especially those ILs have functionalized cation anion, superbase DESs; some of DESs higher than ILs; best ILs, as well [BMIM][BF4] (4.20 mol kg?1), [DETAH][Im] (11.91 mol kg?1), [L-Arg]-Gly 1:6 (4.92 mol kg?1) TBD-EG 1:4 (12.90 mol kg?1), respectively. Besides original mainly providing qualitative predictions, six corrected been proposed improve prediction performance based on experimental data, but only one model is with universal parameters. newly determined further used verify perditions models. comparison indicates qualitatively predicts solubility not all ILs/DESs, while quantitative incapable at all. capable predict constant both DESs, available DESs. For models, parameters provides predictions other always show large deviations (> 83%) compared constants.
