To provide a high temp.-resistant reactor for endothermic catalytic reaction which burns stably in heating ducts by forming the walls of heating and reaction ducts extending mutually in parallel of a heat-resistant and gas- impermeable material and coating respectively the wall faces of the reaction ducts with a catalyst for catalytic reaction and the wall faces of the heating ducts with a catalyst for catalytic burning.
A mixture of combustion gas/air is fed into heating ducts 3 by a feeding pipe piece 4 and is made to flow in the second end face direction sealing the heating ducts in the axial direction. Exhaustion of exhaust gas after catalytic combustion is performed from an opening part 8 installed in the barrier walls of the heating ducts 3 in parallel to the layer of the heating ducks 3 from the side wall of a reactor. All the heating ducts 3 are connected with an exhauste gas pipe piece 7. The mixture of reaction gas is passed through the reactor countercurrently to the mixture of combustion gas/air and is exhausted through a gas pipe piece 6 as a mixture of product by a reaction catalyst. In the reactor, the heating ducts and the reaction ducts are directly adjacent to each other but gases are impermeable through each other. It is possible to perform good heat recovery and utilization of energy.
