ABSTRACT:
A process for reducing the sulfur oxide content of flue gases produced by combustion of sulfur-containing coal containing cations of alkali metals, alkaline earth metals, or both, in ion exchangeable form. Flue gases containing sulfur oxides are recycled to contact coal awaiting combustion. Sulfur oxides are adsorbed on the coal during the contact step, react with alkali metal and alkaline earth metal cations, and are oxidized to form sulfate reaction products. When the treated coal is burned, these reaction products are retained in the coal ash.
