Abstract	Describes fabrication of an organic hybrid of phosphotungstic acid employing an industrial easy-prepared amine, characterized by elemental analyses, infrared spectrum, powder X-ray diffraction, thermal analyses, scanning electron microscopy and energy dispersive X-ray spectroscopy. Researchers investigated an extractive and catalytic oxidative desulfurization process of sulfur-containing model fuel using hexamine–phosphotungstate hybrid as catalyst, hydrogen peroxide as oxidant and acetonitrile as extractant. They optimized the effects of the catalyst dosage and hydrogen peroxide dosage, the reaction time, and the reaction temperature on the removal of dibenzothiophene (DBT) by Taguchi method. Under the predicted conditions, the removal of DBT achieved 99.91%.
