Process for removing nitrogen oxides using ammonia as a reductant and sulfated metallic catalysts
 Nitrogen oxides are removed from flue gas evolving from stationary sources and containing the nitrogen oxides through reduction of nitrogen oxides to nitrogen by passing the flue gas over a catalyst of metal compounds containing oxysulfur compounds in the presence of an ammonia gas.
