摘要： This invention is both a partial combustion process in which the fuel is partially combusted using specific catalysts and catalytic structures and also a catalyst structure for use in the process. The choice of catalysts and supports solves problems in the art dealing with the stability of the overall catalyst structure and ease of catalyst operation. The catalyst structure is stable due to its comparatively low operating temperature, has a low temperature at which catalytic combustion begins, and yet is not susceptible to temperature "runaway". The combustion gas produced by the catalytic process typically is below the autocombustive temperature for the gas mixture; the gas may be used at that temperature, or fed to other combustion stages for ultimate use in a gas turbine, furnace, boiler, or the like.

摘要： This invention is a graded catalyst comprising palladium and also a partial combustion process in which the fuel is partially combusted using that catalyst. The catalyst utilizes a catalytic support structure suitable for high flow rates of combustible gas mixtures through it. The catalyst is situated on the support so that in the flowing gas stream a leading portion of the support has a higher combustion activity, such as by a higher concentration of catalytic metal, than has the trailing portion. The combination of graded catalyst and support provides a low "light off" temperature for the combustible gas (only a low preheat temperature is needed to cause the combustion reaction to begin) and yet does not cause "hot spots" to occur because of excess activity. The combustion gas produced by the catalytic process may be at a temperature below the adiabatic combustive temperature, may be used at that temperature, or fed to other combustion stages for further use in a gas turbine, furnace, boiler, or the like.

摘要： This invention relates to an electrically-heated catalyst (EHC) and a start-up method of a gas turbine engine for combusting a hydrocarbonaceous fuel/oxygen-containing gas mixture using this electrically-heated catalyst. The catalytic structure is electrically heated to a predetermined temperature prior to start up of the turbine so as to reduce emissions during the start-up of the system. The EHC unit is a stacked or spirally wound layering of flat and corrugated thin metal foils which forms a plurality of axially-extending, longitudinal channels. The channels are preferably coated on one surface with a catalytic material, leaving the other surface free from the reaction to act as a heat sink, making the design an IHE (integral heat exchange) catalytic unit. The preferred embodiment of the EHC has electrodes outside of the fuel/oxygen-containing mixture stream, and uses electrical power having a predetermined voltage in the range of 100 to 200 volts to heat the unit. A method for using the EHC in the start-up of a gas turbine is also disclosed wherein an electrical power is applied to heat the EHC a predetermined temperature prior to the fuel/oxygen-containing mixture being introduced and may be left on for a certain period of time after the introduction of the fuel/oxygen-containing mixture. The EHC may be maintained at the desired predetermined temperature by modulating the applied voltage. The electrical power is terminated when any one of several conditions are met including when the heat of the catalytic reaction is sufficient to maintain the catalyst at its steady-state condition or when a certain period of time has elapsed.

摘要： This invention is an improved catalyst structure and its use in highly exothermic processes like catalytic combustion. This improved catalyst structure employs integral heat exchange in an array of longitudinally disposed adjacent reaction passage-ways or channels, which are either catalyst-coated or catalyst-free, wherein the configuration of the catalyst-coated channels differs from the non-catalyst channels such that, when applied in exothermic reaction processes, such as catalytic combustion, the desired reaction is promoted in the catalytic channels and substantially limited in the non-catalyst channels. The invention further comprises an improved reaction system and process for combustion of a fuel wherein catalytic combustion using a catalyst structure employing integral heat exchange, preferably the improved structures of the invention, affords a partially-combusted, gaseous product which is passed to a homogeneous combustion zone where complete combustion is promoted by means of a flameholder.

摘要： This invention aims to provide a process for producing an oxide-dispersion strengthened platinum material which allows zirconium oxide to be more finely dispersed in a platinum material, and to further improve creep strength in an oxide-dispersion strengthened platinum material. This invention provides a process for producing an oxide-dispersion strengthened platinum material where zirconium oxide is finely dispersed in platinum, wherein powdered platinum is poured into water to prepare a platinum suspension; a zirconium nitrate solution and an urea solution are added in the platinum suspension for adjusting the suspension to a given pH to precipitate zirconium hydroxide and thus to form a zirconium hydroxide carrying platinum; the zirconium hydroxide carrying platinum is collected, which is then formed into a molding; the molding is sintered and forged under the conditions whereby secondary recrystallization growth in a platinum crystal proceeds, to form a platinum ingot; and the platinum ingot is cold-rolled in a processing rate of at least 70% and then the product is thermally recrystallized.
