PURPOSE:To enhance catalyst activity by applying one-side corrugation processing ceramic raw sheets containing oxidized catalyst, ceramic fiber and binder by means of a corrugator and forming the same into a honeycomb exhaust gas purifying catalyst by winding or the like. CONSTITUTION:An oxidized catalyst, ceramic fibers and a binder are mixed preliminarily to manufacture slurry. Then, a ceramic raw sheet is manufactured from said slurry by the paper making method, and then the ceramic raw sheet is one-side corrugated by a corrugator to manufacture a one-side corrugated sheet 3 consisting of a plain sheet 1 and a corrugated sheet 2 bonded together. Said one-side corrugated sheets 3 are laminated or wound in proper size and calcined to manufacture a honeycomb exhaust gas purifying catalyst 4. Said catalyst 4 is porous, of high degree of dispersion of catalyst to make the catalyst not only on a surface layer but also the catalyst inside of the layers in contact with the exhaust gas and provide high catalyst activity. |
