Abstract

Carbon capture and storage is needed to reduce the anthropogenic emissions of carbon dioxide (CO2) in atmosphere. Deep eutectic solvents (DESs), due to their low vapor pressure and environmentally benign nature are possible solvents for the carbon capture step. In the present study, the solubility of CO2 in three DESs, namely, reline (choline chloride and urea in a 1:2 molar ratio), ethaline (choline chloride and ethylene glycol in a 1:2 molar ratio), and malinine (choline chloride, malic acid, and ethylene glycol in a 1.3:1:2.2 molar ratio) has been studied in a temperature range of (309 to 329) K at pressures up to 160 kPa. Henry's constants for CO2-DES systems have been determined under t..
