AbstractSome of the desulfurization processes alternative  to conventional  hydrodesulfurization for reduction of sulfur level of transportation fuels as per the regulations  are illustrated  in this review. Various non-severe processes such as, adsorptive desulfurization, membrane based desulfurization, oxidative desulfurization with removal of the oxidation products with either adsorption or extraction, emulsion based desulfurization, ultra-sound or  photocatalytic oxidative desulfurization processes  are briefly discussed.  The use of   various adsorbents used in the recent adsorptive desulfurization processes and their catalytic behavior for selective adsorption are also explained. Oxidative desulfurization followed by adsorption and emulsion based desulfurization are found to be  effective processes to produce ultra clean  transportation fuels.
