CATALYST LAYER FORMING MATERIAL, CATALYST APPARATUS CONSTITUENT MATERIAL, CATALYST APPARATUS, AND METHODS FOR MANUFACTURING THE SAME

摘要

A novel catalyst constituent material for combustion gas purification, which has an extremely good ratio of contact between each catalyst metal particle and an exhaust gas; and catalyst device which uses this catalyst constituent material for combustion gas purification; and a method for producing this catalyst constituent material for combustion gas purificaton. The catalyst constituent obtained by mixing catalyst metal particles and a pore-forming material that disappears at high temperatures into a catalyst supporting material which is a slurry containing fine ceramic particles. The pore-forming material also contains long fibers of cellulose nanofibers and/or short fibers of cellulose nanofibers.
