Wasewar Journal on Future Engineering and Technology 2230 – 7184 8 1 1 5 Low Sulfur Fuel, Desulfurization, Ionic Liquids, Process Now-a-days it is mandatory to provide the low sulfur liquid fuel due to environmental regulation by various countries for the transportation sector which is the big challenge for worldwide refineries. In present paper extractive desulfurization using ionic liquids has been discussed. It is an alternative process for the high energy intensive HDS technology for deep-desulfurization (less than 50 ppm sulfur). Various aspects of the process has been discussed such as extraction time, fuel to ionic liquid ratio, extraction mechanism, and regeneration along with process consideration.
