Ionic Liquids:- As Energy Efficient Solvent For The Extractive Desulfurization of Liquid Fuels

Abstract

A new class of energy efficient solvent, known as ionic liquids, has recently been the subject of demanding research on the extractive desulfurization of liquid fuels. The aim of this study is to investigate the possible application of ionic liquids as green energy efficient solvent because of their unique physical and chemical properties. In this work, Imidazolium based 1-butyl-3methyllimidazolium hexfluorophosphate [BMIM]PF6 and 1-butyl-3methyllimidazolium tetrafluoroborate [BMIM]BF4 were synthesized and employed as extractive agent for the removal of sulfur compounds. The effects of reaction time, reaction temperature, sulfur compounds, and recycling of ionic liquids without regeneration on dibenzothiphene removal of liquid fuel were presented. Also, the desulfurization of real fuels was investigated. The data and results of presented work might be provide significant insights of imidazoled ILs as green solvent for extractive desulfurization of liquid fuels as it can be reused to four cycle without regeneration with considerable extraction efficiency.
