Progress on desulfurization of diesel fuel

New desulfurization technologies have been developed in recent years to reduce the sulfur content in diesel fuel.Oxidative desulfurization(ODS) is considered to be one of the promising methods for super deep desulfurization of diesel fuel.The latest progress of ODS of diesel fuel is reviewed.The ODS researches include homogeneous and heterogeneous catalytic oxidation using H2O2 and O2,oxidation assisted by ultrasound and photocatalytic oxidation.Oxidative desulfurization with air can be carried out under very mild conditions and in a shorter time.Moreoveri,t avoids the shortcoming of high cost and poor stability of H2O2.Therefore,oxidative desulfurization with air will become an important study area for oxidative desulfurization of diesel fuel.
