Catalytic oxidative desulfurization of dibenzothiophene with hydrogen peroxide over mesoporous WOx/TiO2 in a biphasic model oil-acetonitrile system |
| 초록 |
A series of WOx/TiO2 catalysts with different WOx loadings (5 – 20 wt%) were prepared by a wet-impregnation method. Catalytic performance of all the catalysts was evaluated in oxidative desulfurization of model oil under very mild conditions of atmospheric pressure and 50 °C in a biphasic system using hydrogen peroxide as an oxidant and acetonitrile as an extraction solvent. Excellent catalytic activity for the removal of the sulphur-containing compounds from the model oil was observed with 20 wt% WOx/TiO2 catalyst, mainly due to the porosity associated with the TiO2 support, fine dispersed active tungsten oxide species on the mesoporous TiO2 support, and strong interaction between the WOx and the TiO2 surface. Moreover, deprived of undertaking any regeneration steps, the catalyst can be recycled more than five times without losing its catalytic activity. |
