    Abstract: A layered catalyst support or carrier provides a core member for carrying out non-steady state heterogeneously catalyzed processes where reaction gases and their products come in contact with a conventional catalyst applied to the carrier. The support as a carrier is made up of a large number of individually shaped particulate bodies or monolithic packings to be loaded into a reactor and maintained as a fluidized bed or a fixed bed during the non-steady state reaction and the recovery of the products. The support or carrier may consist of glass, quartz, oxides, nitrides, aluminosilicates, magnesium silicates, metals and carbon or their mixtures. Each shaped particle or monolithic packing of this core support is then completely enclosed by depositing thereon a thin protective layer of a nitride, oxide, carbide or chloride of a metal, a non-metal or a mixture thereof, which exhibits a dense, pore-free microstructure and a nonpolar surface having a very low density of acid centers. This outer layer is applied to the core support by a plasma-assisted gas phase deposition. The catalytically active layer is then applied to this protective layer.

    Abstract: A denitration catalyst for use in the reduction of nitrogen oxides contained in an exhaust gas containing highly deliquescent salts as dust with ammonia, which bears thereon a porous coating of a water-repellent organic resin, a porous coating of a mixture of a water-repellent organic resin with inorganic oxide particles, or a porous coating of a mixture of a water-repellent organic resin with catalyst component particles. The denitration catalyst can be prepared, for example, by coating the surface of a denitration catalyst with an aqueous dispersion containing a water-repellent organic resin having a lower concentration, drying the coating, further coating the dried coating with an aqueous dispersion containing a water-repellent organic resin having a higher concentration, and then drying the coating to form a porous coating of a water-repellent organic resin. This denitration catalyst, even when used in the treatment of an exhaust gas containing ash containing highly deliquescent salts, enables the water-repellent porous coating formed on the surface to prevent the salts that have deliquesced from entering the catalyst. This can prevent the deterioration of the catalyst and enables a high catalytic activity to be maintained for a long period of time.

    Abstract: Stabilization of a reduced copper catalyst by a) passivating the catalyst by passing a gas stream that is free of reducing gases and which contains 0.05 to 0.5% by volume of oxygen and an amount of carbon dioxide at least twice the amount of oxygen through a bed of the catalyst until the catalyst is passivated, the proportion of oxygen in said gas stream and the temperature at which it is fed to the bed being such that the temperature of the catalyst does not rise to above 100.degree. C. during said passivation step, and then b) increasing the oxygen content of the gas passing through the bed until the oxygen partial pressure corresponds to that of air at atmospheric pressure. The process may be applied to the stabilization of fresh reduced catalysts or to the stabilization of used, e.g. spent catalysts, before discharge thereof from a reactor.
