    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 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 inexpensive heat exchanger is disclosed, wherein the heat exchanger is made up of a plurality of plates and each plate has at least one channel defined in the plate. The plates are stacked and bonded together to form a block having conduits for carrying at least one fluid and where the exchanger includes an expansion device enclosed within the unit. The plates include construction to thermally insulate the expansion region from the heat exchange region to improve efficiency of the heat exchanger.

    摘要： A process for reforming a hydrocarbon stream is presented. The process involves splitting a naphtha feedstream to at least two feedstreams and passing each feedstream to separation reformers. The reformers are operated under different conditions to utilize the differences in the reaction properties of the different hydrocarbon components. The process utilizes a common catalyst, and common downstream processes for recovering the desired aromatic compounds generated.

    摘要： A novel process for continuously mixing and reacting at least two fluids are disclosed. Excellent mixing and superior pressure drop characteristics are achieved using cyclone mixing where at least two supply channels feed a mixing chamber to create a vortex of the fluids to be mixed. The alignment of the supply channels is such that fluids are introduced into the chamber at both tangential and radial directions. In the case of gas/liquid mixing, particularly advantageous is the injection of the liquid stream tangentially and the gas stream radially. Reaction of the fluids can take place within the mixing chamber or in a separate reactor in fluid communication with the mixing chamber outlet. The process is especially useful for reacting potentially explosive mixtures of reactants where a homogeneous reactor feed mixture is critical to maintaining a non-explosive environment.
