[Object] To provide a catalyst for nitrogen oxide removal having no degradation problem caused by adsorbed water when a temperature is raised sharply and exhibiting excellent nitrogen oxide removal performance and retentive characteristic thereof. [Solution] A catalyst for nitrogen oxide removal, containing a metal-loading zeolite, wherein the zeolite contains a silicon atom, an aluminum atom, and a phosphorus atom in a framework structure, and the amount of water adsorption of the catalyst at 25° C. and a relative vapor pressure of 0.5 is 0.05 to 0.2 (kg-water/kg-catalyst) or less. A method for manufacturing this catalyst for nitrogen oxide removal, the method including the steps of drying a mixed slurry containing a metal source, the zeolite, and metal oxide particles having an average particle diameter of 0.1 to 10 μm and/or an inorganic binder and calcining the resulting dry powder.
A catalyst comprising a zeolite and a metal loaded thereon, wherein the zeolite comprises a silicon atom, an aluminum atom, and a phosphorus atom in a framework structure, and wherein an amount of water adsorption of the catalyst at 25° C. and a relative vapor pressure of 0.5 is from 0.05 to 0.2 kg water/kg catalyst.
A catalyst comprising a zeolite and a metal loaded thereon, the zeolite having a framework structure comprising a silicon atom, an aluminum atom, and a phosphorus atom,
A method for manufacturing a catalyst, the catalyst comprising a zeolite and a metal loaded thereon,
