Desulfurization of diesel via the H2O2 oxidation of aromatic sulfides to sulfones using a tungstate catalyst

Desulfurization of diesel via the H2O2 oxidation of aromatic sulfides to sulfones using a tungstate catalyst
A simplified oxidative desulfurizataion (ODS) catalytic system composed of Na2 WO4, 30% H2 O2 and CH3 CO2 H has been found suitable for the deep removal of sulfur in diesel. By combining ODS and methanol extraction, the sulfur level in a commercial diesel has been reduced from 1100 ppm to 40 ppm. Treatment of model solutions of octane containing dibenzothiophene and 4,6-dimethyl dibenzothiophene with our ODS system shows 100% conversion of the thiophenes to sulfones at 70ºC in less than 1 h.

Abstract

A simplified oxidative desulfurizataion (ODS) catalytic system composed of Na2 WO4, 30% H2 O2 and CH3 CO2 H has been found suitable for the deep removal of sulfur in diesel. By combining ODS and methanol extraction, the sulfur level in a commercial diesel has been reduced from 1100 ppm to 40 ppm. Treatment of model solutions of octane containing dibenzothiophene and 4,6-dimethyl dibenzothiophene with our ODS system shows 100% conversion of the thiophenes to sulfones at 70ºC in less than 1 h.
