    Abstract: Disclosed is a chemical microreactor that provides a means to generate hydrogen fuel from liquid sources such as ammonia, methanol, and butane through steam reforming processes when mixed with an appropriate amount of water. The microreactor contains capillary microchannels with integrated resistive heaters to facilitate the occurrence of catalytic steam reforming reactions. Two distinct embodiment styles are discussed. One embodiment style employs a packed catalyst capillary microchannel and at least one porous membrane. Another embodiment style employs a porous membrane with a large surface area or a porous membrane support structure containing a plurality of porous membranes having a large surface area in the aggregate, i.e., greater than about 1 m2/cm3.

    Abstract: A shift converter (16) in a fuel processing subsystem (14, 16, 18) for a fuel cell (12) uses an improved catalyst composition (50) to reduce the amount of carbon monoxide in a process gas for the fuel cell (12). The catalyst composition (50) is a noble metal catalyst having a promoted support of mixed metal oxide, including at least both ceria and zirconia. Cerium is present in the range of 30 to 50 mole %, and zirconium is present in the range of 70 to 50 mole %. Additional metal oxides may also be present. Use of the catalyst composition (50) obviates the requirement for prior reducing of catalysts, and minimizes the need to protect the catalyst from oxygen during operation and/or shutdown.

The temperature variation in each zone and the temperature level are respectively adjusted by the thickness of each zone and by heat exchange.

    Abstract: A method for hydroprocessing hydrocarbon products, preferably Fischer-Tropsch products, and a reactor useful for performing the method, are disclosed. The reactor includes one or more first catalyst beds comprising a catalyst useful for conducting relatively severe hydroprocessing and one or more second catalyst beds comprising a catalyst useful for conducting relatively mild hydroprocessing. The second catalyst beds are located at a position in the reactor where they can receive the products from the first catalyst bed(s), at least one of each of the first and second catalyst bed(s) comprises a catalyst grading scheme sufficient to remove at least a portion of any particulates from their respective feeds, and the reactor is set up to receive hydrocarbon feeds at a position above or within the first catalyst bed(s) and above or within the second catalyst bed(s). A first hydrocarbon feed with a relatively high boiling point is introduced to the first catalyst bed(s) and is subjected to relatively severe hydroprocessing. A feed comprising 1) the products from the hydroprocessing of the first hydrocarbon feed and 2) a second hydrocarbon feed with a relatively low boiling point is introduced to the second catalyst beds and is subjected to relatively mild hydroprocessing. The catalyst grading scheme minimizes pressure drop build-up through the catalyst beds. The hydrocarbon feeds are preferably derived, in whole or in part, from Fischer-Tropsch synthesis, although they can include products from petroleum refining or other suitable sources. In one embodiment, the relatively high boiling fraction is a predominantly C20null fraction and the relatively low boiling fraction is a predominantly C5-20 fraction.
