Abstract

PURPOSE:Todenitrate catalytically NOx-containing exhaust gas at a comparatively low temperature with NH3 constantly at a high efficiency for a long time by means of arranging a filter medium on both side of catalyst layer in the path of exhaust gas. The catalyst and the filter medium taken out of the denitration zone are returend to teh denitration layers after separation of dust and activation.
