Abstract

Abstract: With increasingly serious air pollution and perfecting environmental protection laws,cleaner production of vehicle fuel is imperative. As a new type of desulfurization technology,more and more researches have focused on electrochemical desulfurization in recent years. Electrochemical desulfurization of vehicle fuel includes oxidation desulfurization and reduction desulfurization. Compared with the traditional hydrogenation desulfurization methods and other non-hydrogenation desulfurization methods,the electrochemistry desulfurization technology as a new desulfurization technology possesses the advantages of moderate operating conditions,high removal effectiveness of sulfur compounds,more simple process and automatic control. Advances in electrochemical oxidation desulfurization and reduction desulfurization,including reaction mechanism,experimental methods and desulfurization effect,are reviewed. Furthermore,the development and application trends of electrochemical desulfurization are proposed. Reaction mechanism,new electrode materials, composite electrolyte,and combination of composite desulfurization process with other desulfurization technology will become the future research directions of electrochemical desulfurization.
