Catalytic oxidative desulfurization of benzothiophene with hydrogen peroxide over Fe/AC in a biphasic model diesel-acetonitrile system
E-mail:
Catalytic oxidative desulfurization (Cat-ODS) of benzothiophene (BT) in n-octane has been investigated with hydrogen peroxide (H2O2) over catalysts of activated carbon (AC) supported iron oxide under mild conditions. The catalyst was characterized by N2 adsorption, XRD, SEM/EDS, TPR and XPS. Under the best operating condition for the catalytic oxidative desulfurization--temperature 60 ℃, atmospheric pressure, 0.15 g Fe/AC, 18 molar ratio of
hydrogen peroxide to sulfur, using acetonitrile as extraction solvent for double extraction--the sulfur content in model diesel fuel (MDF) was reduced from 700 ppmw to 30 ppmw with 95.66% of total sulfur was removed.
