Abstract

PURPOSE: To provide a catalyst with excellent reduction activity at the time of reducing NOx with NH3, SOx poisoning resistance, dust-proofing property, and mechanical strength by forming a compsn. into a cylindrical shape, consisting of titanium oxide, a clayish inorg. substance, a fibrous substance, and a non-noble transition metal cpd. as catlytically active components.
