    摘要: A combinatorial process for simultaneously conducting multiple catalytic chemical reactions in parallel has been developed. At least one catalyst is contained in the reaction zones of a plurality of reactors, each reactor having a reactor insert placed within a sleeve and inserted into a well, the reaction zone of each reactor being formed between a fluid permeable structure attached to the sleeve and a fluid permeable end of the corresponding reactor insert. A fluid reactant is flowed through each reactor where it is contacted with the catalyst contained in the reaction zone to form an effluent. The effluents are removed from the effluent from the reactor and are analyzed.

    摘要: An apparatus is provided which comprises a thermosiphon shift reactor for the conversion of carbon monoxide and the generation of steam for use in a fuel processor for the conversion of hydrocarbon fuels into hydrogen and employs the hydrogen in a fuel cell. The thermosiphon shift reactor comprises a vertically extended shell defining an interior volume containing a vertical axis defining a catalyst zone. The vertically extended shell contains a catalyst zone comprising a shift catalyst wherein a high temperature shift catalyst is disposed in successively tapering layers relative to a low temperature shift catalyst and the catalyst zone is at least partially surrounded by an external jacket which defines a flow passage between the vertically extended shell and the external jacket. A fluid reservoir is located above the vertically extended shell at a height effective to establish a thermosiphon effect between the flow passage and the reservoir which generates steam and provides an essentially uniform temperature at the shell wall.

    摘要: A process and apparatus are disclosed for the operation of a compact water gas shift reactor for use in conjunction with fuel cell to generate electric power from a feedstream comprising a hydrocarbon or an alcohol. The fuel cell comprises a proton exchange membrane which produces electric power from a hydrogen product stream which comprises essentially no carbon monoxide. The hydrogen product stream may be produced from the feedstream in a steam reforming of autothermal reforming zone. The compact water gas shift reactor comprises a vertically aligned vessel having a top end, a bottom end opposite, which defines an interior space. The interior space contains a first water spray zone for contacting a reforming effluent stream comprising hydrogen with a first water stream. A first dispersion zone is disposed below the first water spray zone and above a high temperature shift zone. The high temperature shift zone contains a high temperature shift catalyst to produce a high temperature shift effluent stream. A second water spray zone is disposed below the high temperature shift zone and above a second dispersion zone. A low temperature shift zone is disposed below the second dispersion zone. The low temperature shift zone contains a low temperature shift catalyst to produce a water-saturated hydrogen product stream which comprises less than 50 ppm-mol carbon monoxide. The water dispersion zones simplify the overall shift reaction zone and provide protection for the shift catalysts from temperature shock.

    摘要: A device is disclosed for simultaneous cutting and cauterizing of tissue. The device comprises a cutting edge of a blade. The blade defines a channel within the blade wherein the outlet end of the channel is near the cutting edge. A catalyst is disposed near the outlet end. The channel carries a gaseous mixture to the catalyst where the mixture reacts in the presence of the catalyst and generated heat. The heat generated cauterizes blood vessels as the blade cuts through tissue.
