    • The object of the present invention is to obtain a carbon-monoxide removing technique capable of very effectively reducing/removing carbon monoxide present at one thousand of ppm to several % in a hydrogen-rich treatment-object gas such as a reformed gas obtained by reforming of a fuel such as natural gas, methanol, etc. to a concentration of several tens of ppm (preferably 10 ppm) or lower without excessive loss of hydrogen, even when carbon dioxide, methane are co-existent For accomplishing this object, there are provided two stages of CO removers for removing carbon monoxide from a hydrogen-containing treatment-object gas, the first-stage CO remover removing a portion of the carbon monoxide by methanation thereof through a catalyst reaction, the second-stage CO remover removing the remaining portion of the carbon monoxide mainly by oxidation thereof through a further catalyst reaction involving addition of an oxidizing agent.
    • 本发明的目的是获得一种一氧化碳去除技术,其能够非常有效地减少/除去在富含氢气的处理对象气体中以一千ppm至几%存在的一氧化碳,例如通过重整获得的重整气体 的燃料如天然气,甲醇等至几十ppm(优选10ppm)或更低的浓度,即使在二氧化碳,甲烷共存的情况下,也不会过多地损失氢气。为了实现该目的, 提供了两个阶段的CO去除剂,用于从含氢处理对象气体中除去一氧化碳,第一阶段CO去除剂通过催化剂反应除甲烷化除去一部分一氧化碳,第二阶段CO去除剂除去剩余的 一氧化碳的一部分主要是通过进一步的催化剂反应而氧化,包括加入氧化剂。
