PURPOSE:To prevent inclination of the top of a catalyst layer caused by inclination of a reforming device and to reduce difference in a temperature distribution of the catalyst layer. CONSTITUTION:Since heat transfer particles of a heat transfer layer 12 set on a catalyst layer 10 are smoothly dropped with the movement of the top of the catalyst layer 10 even if the catalyst of the catalyst layer 10 is densely packed from the beginning of packing and the top of the catalyst layer 10 is dropped, a space will not occur between the catalyst layer 10 and the heat transfer particle layer 12. Since a pressing plate 13 on the heat transfer particles is elastically forced by a spring 14, the catalyst layer 10 is always in a pressed state by the heat transfer particle layer 12 and the pressing plate 13. Further, since the temperature of the heat transfer particle layer 12 is raised by heat obtained from a heating space, the upper part of the catalyst layer 10 is made into a thermally insulated state to reduce the temperature distribution of the catalyst layer 10. Besides, in the case of supplying a fuel gas from the top of the catalyst layer 10, when the fuel gas is passed through the heat transfer particle layer 12, the fuel gas receives heat from the heat transfer particles of the heat transfer layer 12 and is supplied in a heated state to the catalyst layer 10. |
