Title: Sulfur tolerant hydrophobic ionic liquid solvent

Abstract

Exemplary embodiments relate to methods for removal of CO.sub.2 and other acid gases from gaseous fuels prior to combustion. Exemplary methods may be used for CO.sub.2 capture, H.sub.2 purification and natural gas sweetening. Exemplary methods use at least one ionic liquid that has excellent CO.sub.2 solubility, selectivity over hydrogen, low viscosity, and resistance to H.sub.2S.
