Removal of sulfur-containing compounds from diesel fraction and fuel oil Available to Purchase

In the work there was considered the process of oxidative desulfurization of fuel oil with the use of hydrogen peroxide and a catalyst—titanium dioxide. It was found that oxidation of fuel oil by hydrogen peroxide in the presence of titanium dioxide can achieve SOC removal by more than 70%. The possibility of photooxidation of sulfur-containing organic compounds (SOC) of fuel oil and diesel fraction under UV irradiation in the range 370–385 nm in the presence of titanium dioxide is studied. Under UV irradiation of fuel oil, the photooxidation processes of SOC are insignificant, which does not lead to significant desulfurization. The study of irradiation of the diesel fraction with UV-light in the presence of a catalyst showed that the SOC photooxidation processes occur. When the diesel fraction is irradiated with UV-light with a wavelength of 380–385 nm and following removal of oxidized products by extraction, the sulfur content is reduced to 0.09 wt %.
