PURPOSE:To reform feed gas with high safety and high efficiency for a long time by heating a specified vessel for a reforming apparatus housing a reforming catalyst bed with an electroconductive coil disposed to its outside and passing feed gas through the reforming vessel. CONSTITUTION:A reforming catalyst bed 15 is formed by packing a mixture of granular electroconductive material (e.g. graphite) 13, with catalyst particles 14 necessary for reforming on a perforated plate 12. A reforming pipe 18 is constructed by providing a heat insulating layer 16 comprising a bad conducting material to the outside periphery of the reforming catalyst bed, and the outside of the reforming pipe 18 is enclosed tightly with a vessel 17 for the reforming pipe comprising a bad conductor (e.g. glass fiber). Further, the outside of the vessel 17 is wound spirally with electroconductive coils 20 interposing a heat insulating material 19 comprising a bad conductor to construct thus a reforming apparatus. Then, feed gas is introduced through a feed gas introducing pipe 7 at a side of an end of the reforming pipe 18 to pass through the reforming catalyst bed 15. Simultaneously, high frequency current is fed to the electroconductive coil 20 via a high frequency generator 21 to heat the reactant and to cause reaction. After proceeding reforming reaction utilizing internal heat generation, reformed gas is discharged from a reformed gas outlet pipe 11.
