Deep desulfurization of fuels has attracted lot of attention from growing number of researchers due to more stringent regulations imposed on sulfur content. There is a great demand to comply the regulation in current technology (hydrodesulfurization) because it requires high pressure, high temperature and high hydrogen consumption. Furthermore, aromatic sulfur compounds are also inefficient to be removed in current technology. Ionic Liquids (ILs) as class of green solvent actually plays

... t role as a promising alternative for desulfurization of fuels. This study focuses on the selection of potential ILs for extraction of aromatic sulfur compound involving the effect of higher alkyl chain, different cation-anion and nitrile group incorporation.
