Production of hydrogen by oxidation of a hydrocarbon fuel comprises feeding the fuel (1) and oxidant (2) into a reactor (3) containing a porous material (4') formed so that flame spreading is prevented in the flow direction, and reacting the fuel with the ...

In an apparatus and method for improved operation of a catalytic reactor, a preferred reactor comprises a vessel (10) having concentric first (35) and second annular catalyst beds (40). Heat transfer fluid flows through expandable heat transfer U-tubes (45...

The component has a plate construction heat transfer EPvice (5) and a reactor (8). The heat transfer EPvice has alternate spaces between its plates (2) for flows of first and second media. The heat transfer EPvice has a tubular outer wall (10) essentially ...
