Abstract

PURPOSE: To regenerate deactivated denitration catalyst consisting of metal oxides supported on SOx resistant carrier, by bringing the catalyst used in reduction with NH3 into contact with a NO-contg. gas at a relatively low temp. so as to thoroughly remove poisonous substances from the catalyst surface.
