Oxidative desulfurization of dibenzothiophene with hydrogen peroxide catalyzed by selenium(IV)-containing peroxotungstate.
With stoichiometric H(2)O(2) as oxidant, dibenzothiophene (DBT) is oxidized to its corresponding sulfone with high efficiency, catalyzed by a sub-valence heteronuclear peroxotungstate, [C(18)H(37)N(CH(3))(3)](4)[H(2)Se(IV)(3)W(6)O(34)], under mild biphase conditions and the catalyst shows remarkable selectivity of catalytic oxidation towards DBT, cinnamyl alcohol and quinoline.
متن کاملOxidative desulfurization of dibenzothiophene with molecular oxygen using emulsion catalysis.
Dibenzothiophene (DBT) is oxidized to the corresponding sulfoxide and sulfone in an emulsion system (W/O) composed of polyoxometalate anion [C(18)H(37)N(CH(3))3](5)[PV(2)Mo(10)O(40)] as both the surfactant and catalyst, using molecular oxygen as the oxidant and aldehyde as the sacrificial agent under mild conditions.
متن کاملThe Study of Biological Technologies for the Removal of Sulfur Compounds
Combustion of sulfur components of fossil fuels such as oil causes the emission of SO2 in the atmosphere and lead to the formation of acidic rain in the environment. The conventional approach for desulfurization of fossil fuels is the chemical procedure of hydrodesulfurization (HDS). However, this method has low efficiency for desulfurization of ring components of sulfur such as dibenzothio...
متن کاملComposite nanolayer photocatalyst-biocatalyst Rhodococcus erythropolis R1 for desulfurization of dibenzothiophene
A nanolayer of composite and Rhodococcus erythropolis biocatalyst was studied for the first time for desulfurization of dibenzothiophene as a model sulfur compound and its performance was compared with that of composite and R. erythropolis alone. The nanolayer of composite was synthesized by sol-gel method from ferrous oxalate and zinc oxalate precursors coated on glass by spin coating techniqu...
متن کاملNovel Methods for Desulfurization of Fuel Oils
Because of the requirement for low sulfur content of fuel oils, it is necessary to develop alternative methods for desulfurization of heavy fuel oil. Due to the disadvantages of HDS technologies such as costs, safety and green environment, new methods have been developed. Among these methods is ultrasoundassisted oxidative desulfurization. Using ultrasound-assisted oxidative desulfurization, co...
