Mechanism Research on Electrochemical Catalytic Oxidation Desulfurization of High Sulfur Coal

Abstract:

Electrochemical desulfurization is a mild chemical desulfurization method. This paper introduces the electrochemical catalytic oxidation method which is used to process High Sulfur Coal samples under acidic condition. Study tells that during the processing of electrochemical catalytic oxidation desulfurization ,pyrite and organic sulfur in coal are oxidized and converted into water soluble sulfur compounds by some active oxygen and other oxidizing agent or high valence ions which are produced on the surface of electrolytic anode.After analyzing the experiments ,another conclusion that the desulfurization process is faster for the added catalyst ion also involving in the reaction is reached.
