摘要：
A green extraction and catalytic oxidative desulfurization (ECODS) system composed of simple tungsten-containing catalyst, 30 wt% H2O2, and ionic liquids was discovered suitable for the deep removal of dibenzothiophene (DBT) in simulated diesel. In the case of the system comprising Na2WO4 center dot 2H2O, 30 wt% H2O2 and 1-butyl-3-methylimidazolium tetrafluoroborate ([Bmim]BF4), the removal of DBT could reach 99.7% at 60 degrees C for 3 hr, which was superior to mere solvent extraction with ionic liquid or catalytic oxidation without ionic liquid. This desulfurization system could be recycled five times with a small decrease in activity.
