Title: Removal of Sulfur Compounds from Simulated Oil with Oxidation by Quaternary Ammonium Peroxotungsto Phosphate Catalysts
Abstract: Catalytic oxidation desulfurization of thiophene-type sulfides,benzothiophene(BT) and dibenzothiophene(DBT),in simulated oil using H2O2 as oxidant and quaternary ammonium peroxotungsto phosphate as the catalyst was investigated.Effect of amount of catalyst,reaction temperature,reaction time and oxidant/oil volume ratio on catalytic oxidation desulfurization was investigated.The results show that the conversions of dienzothiophene and benzothiophene reach above 96.48% and 99.42% respectively,under the conditions of amount of catalyst 0.48%,H2O2/Oil volume ratio of 1∶50,temperature of 60 ℃ after reaction 60 min.The kinetic study indicate that catalytic oxidation desulfurization of simulated oil over peroxy phosphotungstic acid is pseudo first-order reaction.
