Abstract: In this paper，we elaborated the application of Ionic liquids (ILs) in oil desulphurization，including influence factors，desulphurization mechanism，the methods of ILs in oil desulphurization and a novel ILs—immobilized ILs. ILs has unique chemical structure and excellent physical and chemical properties，which show excellent performance in oil desulphurization，compared with other organic solvents. Especially when combined with other processes (such as oxidation)，the desulphurization effect of ILs is better. As ILs is expensive and cannot be completely separated from oil，its industrial application is thus limited. Immobilized ILs can overcome these problems; the development of the immobilized ILs has great potential in oil desulphurization.
