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.
摘要翻译：本发明是一种包含钯的分级催化剂，也是使用该催化剂将燃料部分燃烧的部分燃烧过程。该催化剂使用适合于通过其的可燃气体混合物的高流速的催化支撑结构。催化剂位于载体上，使得在流动的气流中，载体的引导部分具有比具有后部的更高的燃烧活性，例如通过较高浓度的催化金属。分级催化剂和载体的组合为可燃气体提供低的“轻度关闭”温度（仅需要低预热温度才能使燃烧反应开始），并且不会由于过量的活性而引起“热点” 。通过催化过程产生的燃烧气体可能处于低于绝热燃烧温度的温度，可以在该温度下使用，或者进料到其它燃烧阶段，以进一步用于燃气轮机，炉，锅炉等。

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 catalyst comprising palladium on a support containing zirconium and a partial combustion process in which the fuel is partially combusted using that catalyst. The choice of catalysts and supports solves a problem dealing with the long term stability of palladium as a partial combustion catalyst. The catalyst structure is stable in operation, has a comparatively low operating temperature, has a low temperature at which oxidation begins, and yet is not susceptible to temperature "runaway". The combustion gas produced by the catalytic process typically is at a temperature below the autocombustive temperature and may be used at that temperature or it may be fed to other combustion stages for further use in a gas turbine, furnace, boiler, or the like.

摘要： This invention is a process for catalytically burning a combustible mixture of a fuel and an oxygen-containing gas. In particular, the invention is a process for producing a combustion gas at a selected temperature, preferably between 1050.degree. C. and 1700.degree. C., by introducing all of the fuel necessary to attain that temperature to a combustion catalyst, partially combusting the combustible within the combustion catalyst, and homogeneously combusting the remainder of the fuel outside the catalyst. By controlling the temperature within the catalyst, deterioration of that catalyst is prevented.
