Deep desulfurization of a hydrotreated diesel fuel was investigated with H2O2oxidation coupled with solvent extraction intensified by ultrasound. The process parameters for the oxidation desulfurization of diesel fuel, such as the type and dosage of catalyst, co-solvent, ultrasound time, molar ratio of H2O2and sulfur were investigated. The results showed that sulfur content of the hydrotreated diesel fuel was reduced from 140 ppm to 10 ppm with using 2%wt of phosphotungstic acid as catalyst, 20%wt of methanol as co-solvent during the reaction, reaction temperature at 90°C, ultrasound time for 10 min and H2O2/S molar ratio of 16, and ultrasound irradiation had the obvious reinforcement in oxidative desulfurization of diesel fuel.
