A desulfurization method comprises a) mixing well a diesel, the amphiphilic catalyst, and hydrogen peroxide, reacting for 10-300 minutes at ambient temperature and normal pressure, transforming the sulfur-containing compounds in the diesel into sulfone to obtain an oxidized diesel; b) distilling the oxidized diesel obtained in step a) under reduced pressure to obtain the ultra-low sulfur diesel having a sulfur content of less than 10 ppm; and c) separating and recovering the catalyst and sulfone. |
