<P>PROBLEM TO BE SOLVED: To provide a small fuel reformer which effectively uses heat of a heating gas generated in a combustion chamber, is excellent in start-up characteristic and reduces cost-related loads. <P>SOLUTION: The fuel reformer is provided with a tubular insulated vessel 1 which includes an interior space, a burner 2 which is located at the bottom of the interior space and generates a flame in an upward direction and a first multiple tubular vessel 7 which is located inside the interior space and is filled with a reforming catalyst 3. A tubular vessel 16 is filled with a catalyst 15 for transforming CO within a high temperature range and is placed above the tubular insulated vessel 1 leaving a space. The reformer is further provided with second multiple tubular vessels 31 and 38 which house the tubular insulated vessel 1 and the tubular vessel 16, respectively. Spaces between tube walls in the upper parts of the second multiple tubular vessels 31 and 38 are filled with a catalyst 30 for reducing CO concentration within a low temperature range, and spaces between tube walls in the lower parts are filled with a catalyst 35 for removing CO. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
