A catalytic reactor (10) comprises a plurality of fluid-impermeable elements (tubes or plates) (12) defining flow channels (15) between them. Tight fitting within each flow channel (15) is a sheet (16) of corrugated material whose surfaces are coated with catalytic material. At each end of the reactor (10) are headers (18) to supply gas mixtures to the flow channels (15), the headers communicating with adjacent channels being separate. The reactor (10) enables different gas mixtures to be supplied to adjacent channels (15), which may be at different pressures, and the corresponding chemical reactions are also different. Where one of the reactions is endothermic while the other reaction is exothermic, heat is transferred through the wall of the tube (12) separating the adjacent channels (15), from the exothermic reaction to the endothermic reaction. The reactor (10) may be used in a compact plant to perform steam/methane reforming, obtaining the necessary heat by catalytic methane combustion, and also for Fisher- Tropsh synthesis. |
