  • Patent number: 7494517
    Abstract: A device for the catalytic generation of hydrogen from hydrocarbons includes a catalytic converter having feed and distribution channels for starting materials and discharge and collection manifolds for products. The feed and distribution channels and the discharge and collection manifolds are formed from a plurality of identically structured channels. Inlet channels for supplying and distributing starting materials and outlet channels for collecting and discharging products are defined by, in each case, inversely arranged closed and open channel ends. The inlet and outlet channels extend substantially across the entire catalytic converter and are provided in an alternately intermeshing arrangement.
    Type: Grant

  • Patent number: 7001575
    Abstract: A device feeds educts to parallel spaces separated from one another by way of a distributor unit. Outlets of the distributor unit are assigned to the spaces, and evaporator structures for the evaporation of liquid media are provided in the spaces. Each outlet of the distributor unit project into a space. The boiling point of the medium in the distributor unit is maintained above the temperature of the medium in the distributor unit.

  • Patent number: 6644246
    Abstract: A device for evaporating liquids includes a porous, thermally conductive evaporation body, which contains a catalyst material on one surface, while the evaporation body is gas-impermeable on the opposite surface. Liquid which is to be evaporated and, if appropriate an additional fuel, can be fed to the evaporation body. The heat of evaporation required is provided by an exothermic reaction of the liquid or with a gaseous oxidizing agent at the catalyst material.
