Oxidation of Sulfur Components in Diesel Fuel with Tert-Butyl Hydroperoxide Using Chromium Containing Catalysts
Transition metal (iron, cobalt, and chromium) substituted Hexagonal Mesoporous Aluminophosphate (HMA), and AlPO4-5 were studied for the oxidative desulfurization (ODS) reaction of refractory sulfur compounds such as DBT (dibenzothiophene) and 4,6-DMDBT (4,6- dimethyldibenzothiophene). Selective oxidation activity varies with the kind of transition metal employed. The ODS activity of HMA substituted catalyst follows the order: CrHMA >> CoHMA ≥ FeHMA. Comparison between HMA and AlPO-5, CrHMA catalyst shows better performance than Cr-AlPO4-5 catalyst when tert-butyl hydroperoxide is used as oxidizing agent.
