摘要： A steam reactor comprises a pressure shell having inlet and outlet nozzles for each of a process gas and a heating gas, a plurality of metal catalyst tubes packed with a catalyst and located substantially vertically within the pressure shell, one and of each of the catalyst tubes being connected to a pipe and the other end being communicated with the inlet nozzle of the process gas; and a riser pipe located substantially vertically within the pressure shell, one end of the riser pipe being connected to the pipes and the other end being terminated in the outlet nozzle of the process gas. A support member is provided on the pressure shell to support the catalyst tubes and the riser pipe. The plurality of pipes which connect the catalyst tubes and the riser pipe have a diameter which is smaller than that of the catalyst tubes and the riser pipe and a structure capable of taking up the difference in thermal expansion between the catalyst tubes and the riser pipe. The pressure shell may be insulated on a part or the whole of the inner surface thereof.
