Abstract

Among several strategies to capture carbon dioxide the use of ionic liquids is especially interesting due to their unique physicochemical properties and their selectivity towards carbon dioxide compared to other gases. In order to increase the absorption capacity, it is convenient the use of ionic liquids capable to chemically react with CO2, and also maintain the viscosity low enough to allow the gas diffusion. In this context, potential candidates are ionic liquids composed by carboxylate based anions. This project aims to study the mechanisms of chemical absorption of carbon dioxide by different ionic liquids capable of chemically reacting with the gas, and how the viscosity of such liquids are affected by the insertion of different molecular species. Our approach consists in a combination of thermodynamic measurements, spectroscopic determinations and molecular modelling. (AU)
