Description
Summary:Aiming at full sustainability of CO2 separation processes, a series of supported ionic liquid membranes based on environmentally friendly cholinium carboxylate ionic liquids were successfully prepared. Their gas permeation properties were measured and high permselectivities were obtained for both CO2/CH4 and CO2/N2. Cholinium carboxylates are used to prepare sustainable alternative supported ionic liquid membranes (SILMs) for carbon dioxide (CO2) separation. The salts are biodegradable and their ecotoxicities are promisingly low. Their CO2/CH4 and CO2/N2 permselectivities are competitive compared to other membranes based on commonly used ionic liquids.
