Reforming apparatus

A reforming apparatus comprising:

• a reformed gas-producing passage which includes a reforming catalyst section configured to produce reformed gas containing hydrogen as a main component through a steam reforming reaction between a fuel gas and steam, a shift catalyst section configured to reduce an amount of carbon monoxide (CO) in the reformed gas produced in the reforming catalyst section through water gas shift reaction and a CO-selective oxidizing catalyst section configured to further reduce an amount of carbon monoxide (CO) in the reformed gas subjected to the water gas shift reaction by reacting carbon monoxide in the reformed gas with oxygen;
• and
• a combustion gas passage positioned to heat the reforming catalyst section,
• wherein the reformed gas-producing passage includes a first passage and a second passage, the first passage includes the reforming catalyst section and a second heat-recovering section positioned to recover heat from at least one of the shift catalyst section, the CO-selective oxidizing catalyst section and a section of the reformed gas-producing passage between the shift catalyst section and the CO-selective oxidizing catalyst section, the second heat-recovering section is configured to supply the heat to the fuel gas and the steam fed to the reforming catalyst section, said second passage includes a first heat-recovering section positioned to recover heat from a section of the reformed gas-producing passage between the reforming catalyst section and the shift catalyst section and configured to supply the heat to the reforming catalyst section, the first passage is located adjacent to the combustion gas passage, and the second passage is located adjacent to the first passage.
