A compact catalytic reactor (20) for reforming comprises a reactor module (70) to define a multiplicity of first and second flow channels arranged alternately, for carrying first and second gas flows, and a removable gas-permeable catalyst structure (80) with a substrate for example of metal foil is provided in each flow channel in which a chemical reaction is to occur. The reactor is for use with a first gas flow whose pressure is above ambient pressure and is no less than that of the second gas flow. The reactor module (70) may be formed of a stack of plates (72, 74, 75). The module (70) is enclosed within a pressure vessel (90), the pressure within the pressure vessel being arranged to be at a pressure substantially that of the first gas flow. Consequently no parts of the module (70) are under tension. This simplifies the design of the reactor module, and increases the proportion of its volume occupied by the catalyst |
