| abstract |
The present specification disclosed a hydrogennrefinement apparatus comprising a reformed gas feedingnpart containing at least a hydrogen gas and water vapor,nand a reaction chamber equipped with a carbon monoxidenshifting catalyst body downstream said reformed gasnfeeding part, wherein said carbon monoxide shiftingncatalyst body comprises a carrier supporting Pt, thencarrier being composed of at least one metal oxidenhaving a BET specific surface area of 10 m 2 /g or more,nand a method for operating the apparatus. The presentninvention provides improved heat-resistance of the COnshifting catalyst body, and can operate stably even ifnthe apparatus is activated and stopped repeatedly. |
