Estimating the term…
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.
A catalyst layer forming material comprising a catalyst carrier, which is slurry containing ceramic fine particles, mixed with catalyst metal particles and a pore former to be evaporated at high temperature,
A method for manufacturing a catalyst layer forming material, the method comprising mixing a catalyst carrier, which is slurry containing ceramic fine particles, with catalyst metal particles and a pore former to be evaporated at high temperature, wherein the pore former contains long fibers formed of cellulose nano-fibers and produced by mechanical defibration and short fibers formed of cellulose nano-fibers and produced by chemical defibration.
