摘要： Disclosed is a method for producing a catalyst for removing nitrogen oxides which comprises dispersing a hydrated titanium (Ti) oxide or dried material thereof, tungstic acid or a salt thereof, and cerium (Ce) dioxide in a dispersion medium to form a sol-like material, mixing the sol-like material with an aqueous medium to form a catalyst slurry or paste, supporting the catalyst slurry or paste on a catalyst carrier, and then calcinating the carrier; in which catalyst the Ce dioxide is prevented from being embedded in the Ti oxide to realize such a high degree of dispersion of the Ce dioxide on the surface of the Ti oxide as comparable with the case wherein cerium ions are dispersed in micro voids of a zeolite by ion exchange; and the catalyst is free from the occurrence of such phenomena as sintering of the Ti oxide, and deterioration of zeolite with steam when a zeolite is used as carrier.

摘要： The catalyst structure of the present invention for purifying an exhaust gas is preferable for increasing the contact of an exhaust gas, to be treated, with a catalyst by disturbing the flow of the exhaust gas in a gas flow passage thereby obtain a highly efficient and compact apparatus for treating the exhaust gas. Such catalyst structure is produced by forming two or more catalyst elements each supporting a catalyst component on its surface and having flat plate portions and level-changing portions formed alternately therein with the angle formed between the flat plate portion and the level-changing portion being in a specific range, and then stacking the catalyst elements in a frame. A catalyst structure is also obtained by stacking a large number of the catalyst elements described above through metallic, ceramic, or glass netlike members interposed therebetween and each having a large number of perforated holes. The catalyst structure has such advantages that dust is hardly deposited between the catalyst elements, that a sufficiently high strength can be obtained even when the thickness of catalyst elements is reduced, and that the catalyst structure can be placed in an exhaust gas flue to use as an exhaust gas treating apparatus. When the exhaust gas treating apparatus is employed, an efficient exhaust gas treatment can be effected without damaging the catalyst elements while repressing the pressure loss.

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.
