Gas purification-treating agents and gas purifying apparatuses

A gas purifying apparatus for removing carbon monoxide and/or hydrogen contained in a gas, the apparatus comprising:

• a first treating agent layer consisting of an adsorbent having excellent water adsorptivity, and a metal or metal compound, carried on the adsorbent, for effecting oxidation treatment of carbon monoxide and/or hydrogen in the presence of oxygen;
• and
• a second treating agent layer containing a treating agent consisting of an adsorbent having carbon dioxide adsorptivity and a metal or metal compound, carried thereon, for effecting oxidation treatment of carbon monoxide and/or hydrogen in the presence of oxygen;
• the first and second treating agent layers being packed in a container having a gas inlet and a gas outlet in this order in terms of the gas flow.

• a first adsorbent layer containing an adsorbent for removing water contained in the gas;
• a second adsorbent layer containing an adsorbent for removing carbon dioxide contained in the gas;
• and
• a treating agent layer containing a mixture of a plurality of treating agents each consisting of an adsorbent having carbon dioxide and/or water adsorptivity, and a metal or metal compound, carried on the adsorbent, for effecting oxidation treatment of carbon monoxide and/or hydrogen in the presence of oxygen;
• the first and second adsorbent layers and the treating agent layer being packed in a container having a gas inlet and a gas outlet in this order in terms of the gas flow.

A gas purifying apparatus for removing carbon monoxide and/or hydrogen contained in a gas, the apparatus comprising:

• an adsorbent layer containing an adsorbent for adsorbing and removing water contained in the gas;
• and
• a treating agent layer containing a mixture of an adsorbent for adsorbing and removing carbon dioxide contained in the gas and a treating agent consisting of an adsorbent for adsorbing and removing carbon dioxide, and a metal or metal compound, carried on the adsorbent, for effecting oxidation treatment of carbon monoxide and/or hydrogen in the presence of oxygen;
• the adsorbent layer and the treating agent layer being packed in a container having a gas inlet and a gas outlet in this order in terms of the gas flow.
