PURPOSE:To make a compact device for reforming with high reforming efficiency, by burning fuel in the presence of a combustion catalyst packed between the reforming pipes to react a mixed fluid of hydrocarbons with steam in the presence of a catalyst and a casing. CONSTITUTION:Hydrocarbons are blended with steam, reacted with it in the presence of the reforming catalyst 2, and a given number of the reforming pipes 3 to convert the mixture into a gas containing at least hydrogen are set in the casing 1 to constitute the titled device for reforming. A mixture of the combustion catalyst 7 and the heat accumulative material 8 is packed between the casing 1 and the reforming pipes 3, to form the heat accumulative layer 9. A gaseous fuel and air for combustion are introduced from the feed opening 10 for fuel to the device, the fuel is burned in the presence of the catalys 7, the pipes 3 are heated, and the combustion gas 11 is exhausted from the exhaust vent 11. While the hydrocarbons and steam are fed from the feed header 4 for raw material through the valve 5 to the pipes 3, and prepared reformed gas is taken out from the header 6. |
