摘要

Introduction The deep desulfurization of engine fuels has attracted much attention recently, because of increased stringent fuel specifications and environment pollution. Conventional hydrodesulfurization (HDS) is difficult to remove the refractory compounds such as 4,6-dimethyl-dibenzothiophene (4,6-DMDBT) due to steric hindrance [1]. In order to obtain the fuels with ultra-low sulfur contents, it is feasible to combine HDS with the oxidative desulfurization method (ODS), because they are chemically complementary [2]. We report here the synthesis of an amphiphilic hybrid material [Bmim]3PW12O40, and SiO2-supported [Bmim]3PW12O40 catalysts which exhibited significantly high activity using H2O2 solution as the oxidant in the oxidation of 4,6-DMDBT.
