Desulfurization of Gasoline by New Nanocomposite (TBA-FePOM@NiO) as an Efficient and Recyclable Catalyst

In this research, in order to obtain the clean gasoline, a new nanocomposite, TBA-FePOM@NiO was synthesized via the sol-gel method and tested as a catalyst for oxidative desulphurization (ODS) of gasoline. The nanocomposite was successfully prepared by reaction of mono Fe-substituted polyoxometalate [N(CH3)4]4PW11FeO39 (hereinafter TBA-FePOM) and nickel oxide (NiO). The incorporation of the materials was confirmed by FT-IR ،XRD ، UV-Vis and SEM. The catalytic activity of nanocomposite was tested on real gasoline fuel in the presence of CH3COOH:H2O2 as an oxidant system. The results are compared with the oxidation process of prepared model sulfur compounds at the same conditions. The obtained results show that the nanocatalyst to be able to have oxidative desulphurization of gasoline with high yield. The synthesized heterogeneous nanocatalyst could be separated and recycled successfully after five times. in this study main factors such as temperature, time of reaction and dosage of catalyst were investigated.
