摘要: 为深度脱除燃油中的有机硫化物,本合成了三种季铵型钒代多金属氧酸盐:[C18H37N(CH3)3]3+x [PMo12-xVxO40](x=1,2,3),并与疏水性离子液体[Bmim]PF6/H2O2 (30 wt %)构建了离子液体乳液脱硫体系,同时考察了在不同条件下该乳液脱硫体系在模型油中的催化脱硫活性,且该体系对真实柴油表现出很的催化活性,最后对该体系的脱硫机理进行了阐述。

Abstract: Aiming at deep desulfurization of the gasoline, three amphiphilic catalysts [C18H37N(CH3)3]3+x [PMo12-xVxO40](x=1,2,3) were prepared and characterized. The amphiphilic vanadium (V)-substituted polyoxometalates were dissolved in water-immiscible ionic liquid ([Bmim]PF6) forming a H2O2-in-[Bmim]PF6 emulsion desulfurization system with 30 wt % H2O2 as oxidant. The catalytic oxidation of sulfur-containing model oil has been studied in detail under various reaction conditions using this system. The ionic liquid emulsion system showed high catalytic oxidative activity in the treatment of actual gasoline. Moreover, the mechanism of catalytic oxidation desulfurization was also elaborated.
