Desulfurization of Model Oil Fuel with CuW/TiO2?GO through Photocatalytic Oxidation
Keywords:
Desulfurization, oxidation, photocatalyst, graphene oxideAbstract
Graphene oxide (GO) was co-modified with copper, tungsten, and titanium oxide. The resulting samples were characterized using the X-ray diffraction (XRD), scanning electron microscopy, X-ray photoelectron spectroscopy, and nitrogen adsorption?desorption techniques. XRD analysis indicated the coexistence of TiO2, CuO, and WO3 in the catalysts. The catalytic performance of the resulting materials in the desulfurization of model oil fuel was evaluated using a photocatalytic reactor. The desulfurization rate, the refined oil yield, and the increase in the octane number of model oil reached 100%, 99.4%, and 1.6 units, respectively, under suitable conditions of a metal content of 10.3%, a metal ratio of 0.7, a reaction temperature of 313K, a reaction time of 1 h, a catalyst/oil ratio of 0.25.
