Abstract: At the time of loss of coolant accident, when station blackout occurs, hydrogen, radioactive nuclides, and steam are discharged from a broken portion of a pipe connected to a reactor pressure vessel into the primary containment vessel. A passive autocatalytic hydrogen treatment apparatus installs a catalytic layer and heat exchanger tubes of a heat exchanger in a casing. High-temperature steam including hydrogen and radioactive nuclides is supplied into the heat exchanger tubes and heats gas supplied into the casing 3. The steam is condensed in the heat exchanger tubes and generates mists. The mists are removed by a mist separator together with the radioactive nuclides. The gas including hydrogen fed from the mist separator in the casing is heated by the aforementioned steam and is introduced into the catalytic layer. Hydrogen is combined with oxygen in the catalytic layer to steam.

Abstract: 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.

Abstract: Use of a metallic material containing chromium as a substrate of an exhaust gas purifying catalyst has a problem that the chromium contained in the substrate migrates to a catalytically active component and reacts with the catalytically active component to reduce exhaust gas purification performance. Thus, a film which inhibits the chromium contained in the substrate from migrating is arranged on the substrate's surface. The film is desirably formed by oxidizing a substrate in the air. It is also desirable that a substrate containing aluminum therein be oxidized to cause aluminum contained in the substrate to separate out and thereby form an alpha-alumina film. The film is preferably such that, when the exhaust gas purifying catalyst is heated at 850° C. in the air for 300 hours, the amount of chromium migrated to the catalytically active component is controlled to 0.5 percent by weight or less based on the catalytically active component.

Abstract: A catalyst for use in purifying exhaust gas from an internal combustion engine. The active components of an exhaust gas purification catalyst for an internal combustion engine tend to be melted or softened and then to move outside the carrier, because the components become in contact with exhaust gas at a high temperature. Hence, anchoring materials are provided between carriers in order to suppress the moving of catalytically active components. Anchoring materials 22 do not form compounds with catalytically active components 24, and are selected from substances that do not melt even in contact with exhaust gas at a high temperature. When the active components contain sodium, potassium, cesium, lithium, strontium, barium, noble metals and the like, the best anchoring material is MgO. The anchoring material functions as a barrier that prevents the moving of active components.

Abstract: 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.

The catalyst chemically adsorbs NOx under the condition that a stoichiometric amount of a gaseous oxidizing agent present in the exhaust gas is larger than that of a gaseous reducing agent present in the exhaust gas for reducing NOx, while NOx being adsorbed is catalytically reduced in the presence of the reducing agent under the condition that the stoichiometric amount of the oxidizing agent is not larger that of the reducing agent. Thereby, NOx, the lean burn exhaust gas in the engine can be effectively made harmlessly.
