    摘要: This invention provides a method involving the use of a non-ammonia-based deNOx catalyst for reducing the amount of NOx in exhaust combustion gas discharged from a boiler and an internal-combustion engine, wherein NOx and CO contained in exhaust gas are allowed to selectively react to reduce and remove NOx. This method involves the use of a catalyst comprising a cerium-zirconium composite oxide with Au supported thereon or a catalyst comprising a cerium-oxide-containing porous carrier with zirconium and Au supported thereon. Use of such catalyst enables purification of NOx and CO in exhaust gas and also enables generation of hydrogen.

    摘要: According to the present invention, it is possible to provide a catalyst which includes metal clusters containing a non-platinum element as the catalyst active ingredient, these metal clusters having species of a metal having different valences, and exhibits an improved electrode performance per unit price of the used metal, compared to catalysts using platinum. When this catalyst is applied to an electrode catalyst for fuel cell, a low-cost fuel cell system can be realized without using expensive platinum as the active ingredient. This catalyst can be applied to DMFC and PEFC fuel cells.

    摘要: An adsorbing substance made of a material having an acid center in its molecular frame is installed in a passage for steam generated in a reactor pressure vessel 1. The adsorbing substance adsorbs and holds N-16 compound for decay. Therefore, the amount of N-16 entering into a turbine system is decreased and dose in the turbine system can be reduced.
