摘要： A seal plate within a gas fixed reformer divides an upper plenum and a lower plenum to force combustion products along the heat exchange surface of the reactors. The seal plate has a sealed horizontal central portion and a vertical perpendicular portion extending to the bottom of the shell. The entire seal plate is exposed to gas in the discharge plenum, whereby differential expansion of various seal plate portions is avoided.

摘要： A fuel cell power plant, generally, has a fuel cell stack for electrochemically converting a hydrocarbon fuel into electricity. In order for the hydrocarbon fuel to be used by the fuel cell stack, it must be steam reformed into a hydrogen-rich process gas. This process gas has a carbon monoxide level that would be detrimental to the fuel cell stack, so the process gas is passed through a shift converter to decrease the carbon monoxide level therein prior to feeding the process gas to the fuel cell stack. In order to decrease the level of carbon monoxide without the need to increase the size of the shift converter catalyst bed, or lower the temperature of the process gas as it enters the shift converter to an undesirably low temperature, the shift converter design that utilizes an upstream adiabatic zone and a downstream actively cooled zone. The actively cooled zone is cooled by a pressurized water coolant which boils as it cools the process gas stream. The coolant entering the shift converter is essentially a single phase water stream, and the coolant exiting the shift converter is a two phase water-steam mixture.

摘要： A steam reformer for converting a reactor fuel into a product gas includes a segmented catalyst bed. The steam reformer side walls have a thermal coefficient of expansion which is greater than the thermal coefficient of expansion of the catalyst. By forming low volume catalyst bed segments in the hotter portions of the catalyst bed, slumping and subsequent damage of the catalyst pellets is minimized. The catalyst bed is divided into segments whose volumes are inversely proportional to the temperatures of the various zones in the reformer. The segments are formed by utilizing sequential catalyst support assemblies which include perforated catalyst support members that are differentially spaced apart from each other by support assembly legs having varying lengths. Catalyst support assemblies with shorter length legs are used in the hotter zones of the reformer, and support assemblies with progressively longer length legs are used in the cooler zones of the reformer.
