Abstract： |
The catalytic oxidation-extracting separation process for desulfurizing oil product includes the catalytic oxidation of benzothiophene, dibenzothiophene and other organic sulfides with hydrogen peroxide as oxidant and the mixture of tungsten-containing inorganic acid and quaternary ammonium salt as catalyst; subsequent extraction with acetonitrile/water azeotrope as extractant; and desulfurizing of the reacted product in polar solvent. Experiment shows that the said process has low oxidant consumption, low cost, high extraction rate, simple technological process, high safety and high desulfurizing rate. |
