Oxidative desulfurization of diesel using ozone as the oxidant

The purpose of this study is to design a proper process for the sulfur reduction of diesel fuel usingOzon-assisted oxidative desulfurization. The diesel fuel with ۰.۱۴ (wt.%) has been used for this purpose.In this regard, oxidation of diesel-acetonitrile mixture has been carried out in the two-neck roundbottomflask. After the oxidation process, the sulfur-containing components have been removed byextraction with acetonitrile. Different scenarios have been examined and it has been shown that the bestdesulfurization is obtained when two-stage oxidation of fuel and solvent is carried out. The bestdesulfurization rate is about ۷۶%. The effect of temperature has been also studied and results have beenshowed that, there is an optimum temperature in the gas-phase oxidation.
