Abstract

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.
