Abstract: Desulfuriztion methods，including electrochemical desulfurization of raw coal in acidic/ alkaline medium，electrochemical flotation of raw coal，and flue gas electrochemical desulfurization are presented. Valuable references are given for choosing the conditions of desulfurization by comparing the rates of sulfur removal and discussing the factors of FGD. The development direction and prospect of electrochemical desulfurization are discussed.
