ADSORBENT FOR CARBON MONOXIDE, GAS PURIFICATION METHOD, AND GAS PURIFICATION APPARATUS

摘要

The adsorbent for carbon monoxide of the present invention is obtained by activating a Cu-ZSM5 type zeolite prepared as a catalyst for removal of NOX through heating at 450 to 600° C. in an inert gas atmosphere containing no moisture. The gas purification method of the present invention includes removing carbon monoxide as a trace amount of impurities contained in a gas by a temperature swing adsorption method, wherein the adsorbent for carbon monoxide according to claim 1 is used, and a regeneration operation of the adsorbent for carbon monoxide is carried out at 200 to 350° C.
