A highly compact heat integrated fuel processor, which can be used for the production of hydrogen from a fuel source, suitable to feed a fuel cell, is described. The fuel processor assembly comprises a catalytic reforming zone (29) and a catalytic combustion zone (28), separated by a wall (27). Catalyst able to induce the reforming reactions is placed in the reforming zone and catalyst able to induce the combustion reaction is placed in the combustion zone, both in the form of coating on a suitable structured substrate, in the form of a metal monolith. Fe-Cr-AI-Y steel foils, in corrugated form so as to enhance the available area for reaction, can be used as suitable substrates The reforming and the combustion zones can be either in rectangular shape, forming a stack with alternating combustion / reforming zones or in cylindrical shape forming annular sections with alternating combustion / reforming zones, in close contact to each other. The close placement of the combustion and reforming catalyst facilitate efficient heat transfer through the wall which separates the reforming and combustion chambers. |
