Abstract: PURPOSE: Provided is a reactor for carrying out non-adiabatic process, which show improved service life and reactive efficiency by changing its wall thickness and wall material along the flow direction of a medium in the reactor. CONSTITUTION: As the reactor for carrying out a process under non-adiabatic conditions, a heat exchanger and a reactor where heat generating reaction or heat consuming reaction is performed are exemplified. For example, a hydrocarbon supply material is steam-reformed to yield the gas containing hydrogen and carbon monoxide by the reaction shown in formulae I (CnHm+nH2O→nCO+(n+m/2)H2(-ΔH<0)) and II (CO+H2O→CO2+H2(-ΔH=9.84kcal/mole)). Since the maximums of the temperature of the tube wall of the reactor and of the flow rate of heat appear at the different axial positions, the reactor is constituted so that the wall thickness is changed along the axial direction of the wall. Namely, the wall thickness at the position of the highest temperature is made thickest and that at the position of the largest flow rate of heat is made thinnest. Therefore, the flow rate of heat of the reactor is increased and its durability is improved.
