Deep Desulfurization of Diesel Fuel Oxidized with H₂O₂ Coupled with Solvent Extraction Intensified by Ultrasound

Abstract:

Deep desulfurization of a hydrotreated diesel fuel was investigated with H₂O₂ oxidation 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 H₂O₂ and 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.
