<P>PROBLEM TO BE SOLVED: To provide a reformer able to avoid reforming catalyst oxidation in a reforming part and able to protect its degradation when the reformer equipped with the reforming part, a CO converting part and a CO removing part in a steam reforming method of a hydrocarbon is started or stopped and its operation method. <P>SOLUTION: The reformer is equipped with a steam reformer, the CO converting part and the CO removing part. The reforming catalyst oxidation is protected by feeding a partial combustion gas obtained from incomplete combustion of a fuel gas at a combustion part of the steam reformer to the reforming part of the steam reformer when it is started or stopped. The reformer is equipped with a partial combustion gas oxidizing part which oxidize the partial combustion gas branched from a conduit at a downstream side of the CO removing part by air and a combustion gas bypass line from the combustion part to the oxidizing part. <P>COPYRIGHT: (C)2003,JPO |
