The oxidizing reagent used was tert-butyl hydroperoxide. The catalyst was prepared using wet impregnation method and characterized by FESEM-EDX and X-ray photoelectron spectroscopy. The effects of dopants, catalyst loading, dopant loading, and calcination temperature of the catalyst were investigated. Further investigations on doped molybdenum revealed that Fe-MoO3/Al2O3 catalyst calcined at 500°C with 10% of Fe loading and 9g/L, the catalyst was able to reduce the sulfur in commercial diesel from 440 to 88ppmw. Response surface methodology involving Box-Behnken was employed to evaluate and optimize Fe-MoO3/Al2O3 preparation parameters (calcinations temperature, catalyst loading, and Fe loading) and their optimum values were found to be 550°C, 10g/L and 10% of calcination temperature, catalyst loading, and Fe loading.
