<P>PROBLEM TO BE SOLVED: To provide a CO removing device compactified, reduced in cost, and easily manufacturable, by integrating a low-temperature shift converter with a CO selective oxidation reactor without connecting them by pipes, and sending reformed gas and air to the CO selective oxidation reactor by uniformly mixing them. <P>SOLUTION: The low-temperature shift converter 56 is integrated with the CO selective oxidation reactor 57 by vertically superposing them to hold a partition board 70 between them. Openings 71 for reformed gas inlet are provided at a plurality of spots in the partition board 70 in the circumferential direction, and the reformed gas 54 with the CO content reduced by the low-temperature shift converter 56 is dispersedly run from each opening 71 of the partition board 70. A mixing part 75 mixing the reformed gas 54 dispersedly run from each opening 71 of the partition board 70 with the air 58 is formed on the upper side of the CO selective oxidation reaction part 79 of the CO selective oxidation reactor 57. An orifice 72 and an opening 73 are provided at one spot in the mixing part 75, and the reformed gas 54 is sufficiently mixed with the air 58 to supply them into the CO selective oxidation reacting part 79. <P>COPYRIGHT: (C)2008,JPO&INPIT |
