Abstract: A mesoporous carbon containing tungsten was prepared using Na₂WO₄ and EDTA-2Na as the source of tungsten and carbon and characterized by XRD, FT-IR, SEM and BET. The results show that the tungsten oxide with crystal water (WO₃·H₂O) is formed on the surface of mesoporous carbon. Compared with pure mesoporous carbon, the total surface area of mesoporous carbon containing tungsten decreases. An extraction-catalytic oxidation desulfurization (ECODS) system was constructed using mesoporous carbon containing tungsten as catalyst, H₂O₂ as oxidant and ionic liquids (ILs) 1-butyl-3-methyl imidazolium tetrafluoroborate (BMIM BF₄) as extraction agent. The effects of tungsten oxide loading, reaction temperature, the amount of H₂O₂, the amount of catalyst and ILs dosage and different types of sulfur compounds on the removal of DBT was studied. Under the optimal conditions, the removal rate of DBT reaches 98.6% for DBT, 65.6% for 4, 6-DMDBT, 61.2% for BT, 57.8% for TH and 64.3% for actual gasoline, respectively. The desulfurization rate is slightly decreased when the catalyst is reused five times.
