Abstract
ABSTRACTThe phosphomolybdic acid has been successfully supported on functionalized ionic liquid (IL) modified mesoporous silica SBA-15. Subsequently, the obtained products were calcined at different temperatures. The oxidative desulfurization of model fuel containing benzothiophene, dibenzothiophene or 4,6-dimethyldibenzothiophene has been carried out with HPMo-IL/SBA-15 calcined at various temperatures. Based on desulfurization rate and cost, the optimum calcination temperature of HPMo-IL/SBA-15 catalyst was around 400 °C. More molybdenum oxide active sites were shown by the decomposition of the IL at the higher temperature, which caused better desulfurization performance.
