REFORMING APPARATUS AND OPERATION METHOD THEREOF

摘要

There is provided a reforming apparatus which shows high efficiency and excellent operation-starting performance. The present invention relates to a reforming apparatus having a gas-producing passage which includes a reforming catalyst section, a shift catalyst section and a CO-selective oxidizing catalyst section arranged in this order along a gas flowing direction; and a combustion gas passage for heating the reforming catalyst section, the shift catalyst section and the CO-selective oxidizing catalyst section. The reformed gas-producing passage is formed of a first passage and a second heat-recovering section which recovers heat from the gas having passed through the shift catalyst section and the gas having passed through the CO-selective oxidizing catalyst section and supplies heat to a fuel gas and steam fed to the reforming catalyst section; and a second passage including the shift catalyst section, the CO-selective oxidizing catalyst section, and a first heat-recovering section which recovers heat from the gas having passed through the reforming catalyst section and supplies the heat to the reforming catalyst section.
