Ionic Liquid, Magnetite, Gasoline, Desulfurization

طDuring recent years some strict regulations are established to reduce the sulfur content of the fuels. Magnetic iron oxide nanotechnology has started a new trend which is more efficient and economic than the conventional methods. Herein, the magnetic removal of aromatic sulfur compounds from gasoline has been investigated. In the present work, a novel magnetic nanosorbent through surface modification by an ionic liquid was synthesized and characterized by XRD, TEM, and FTIR techniques. Effective parameters were optimized and studies were carried out on a model oil and a real sample under optimal conditions. It was found that the supported ionic liquid was well efficient in the removal of aromatic sulfur containing compounds and was a promising sorbent in deep desulfurization treatments. The used sorbent could be regenerated through convenient magnetic decantation and stripping by carbon tetrachloride.
