The Deep Oxidative Desulfurization of Fuels Catalyzed by Surfactant-type Octamolybdate in Acidic Ionic Liquids

摘要

Four surfactant-typc oclamolybdatcs were synthesized, characterized, and then used as effective catalysis associated with H_2O_2 as oxidant in the acidic ionic liquid, which has been found suitable for deep removal of organic sulfur in fuels. Under the favorable conditions, the sulfur removal could reach almost 100%, which was much belter than desulfurization performance by the simple extraction with acidic ionic liquid. Moreover, this acidic ionic liquid can be recycled six times by distillation without obviously decrease in activity. Meanwhile, the mechanism of oxidation desulfurizalion was also elaborated.
