Summary: This investigation successfully removes sulfur-based compounds by a combination of absorptive and oxidative desulfurization processes using a series of novel Bi-based bifunctional photo electrocatalysts. The results showed that the catalysts had higher efficiency in absorptive desulfurization and better results in oxidative desulfurization. Among the catalysts, photoelectrocatalytic desulfurization performed best in dibenzothiophene removal.

Summary: The incorporation of iron and sulphate ions on TiO2 nanoparticles improved the catalytic performance, and a multifunctional and visible-light active photocatalyst was designed to remove pollutants from transportation fuels and water. Doping with a low amount of iron enhanced the photocatalytic performance, with the 1.2%S-0.5%Fe-TiO2 photocatalyst showing the highest activity under visible light irradiation. The improved electron charge transfer behavior of this photocatalyst was confirmed by electrochemistry measurements, and the stability and recyclability of the best photocatalyst were evaluated.

Summary: A core-shell porous catalyst coated with TiO2-fibrous silica (KCC-1) was prepared and showed excellent catalytic desulfurization performance. The unit desulfurization rate was significantly improved without additional oxidants. The adsorption-catalysis-resorption desulfurization system was effective, enhancing the reaction rate and achieving selective adsorption and coupling desulfurization. Furthermore, the spent catalyst could be regenerated without a decrease in desulfurization rate.

Summary: Sulfur dioxide emissions from fossil fuel combustion can have negative impacts on health and the environment. The current hydrodesulfurization method used by refineries has limitations in producing ultralow sulfur diesel at reasonable costs. Ionic liquids have been explored as potential alternatives, but there is limited research on their industrial-scale feasibility and integration into process simulators. This study screened and evaluated 26 commercially available ILs for desulfurization of diesel fuel using COSMO-based models and Aspen Plus, and proposed an optimized process using 1-butyl-3-methylimidazolium thiocyanate that achieves ULSD with minimal loss of the IL.
