CO2 capture with ionic liquids

In order to enhance people’s quality of life different ways of obtaining energy have been developed.  Unfortunately, they are not free of charge; they involve pollution and emissions of gases all of which accentuate global warming. 

The aim of this research is to investigate potential alternatives to capture CO2 through components with better properties than the ones used in current methods. The substances chosen in this study belong to a promising group of solvents called ionic liquids (ILs). ILs show a remarkably good CO2 solubility and a suitable selective CO2 absorption to make ILs the future CO2 absorbents from flue gas. In this master thesis the solubility of CO2 in three phosphonium based ionic liquids has been studied obtaining very interesting results since one of the highest CO2 solubility in physical ILs has been measured.
