Abstract

PURPOSE: To prevent the poisoning of the catalyst due to SO3 and to denitrate efficiently at a lower temperature, by introducing the exhaust gas to catalyst layer for the denitration after SO3 has been removed at the layer of Al2O3 provided at the preceding stage for the catalyst layer, when NOx in the exhaust gas from combustion is reduced catalytically.
