ABSTRACT OF THE DISCLOSURE A solid form adsorbent of carbon monoxide, that is ob- tained by the process including the following steps. First, copper salts or copper oxide is stirred in a solvent. Then, into the solution or suspension thus obtained, active carbon is added. Finally, the solvent is removed by means of pres- sure reduction, distillation, etc. The carbon monoxide adsorbent produced according to this invention adsorbs carbon monoxide rapidly when it is brought into contact with a mixed gas. The adsorbed carbon monoxide can be readily separated and discharged through either heating the carbon monoxide adsorbent to about 60°C or reducing the partial pressure of carbon monoxide. The carbon monoxide adsorbent obtained in accordance with the present invention is stable relative to the water content in the mixed gas, and it is capable of separating carbon monoxide directly from the mixed gas con- taining the water. Also, the separated carbon monoxide does not contain the vapor of the solvent from the carbon monoxide adsorbent. Therefore, it is not necessary to provide equip- ment to collect the solvent vapor. Furthermore, this carbon monoxide adsorbent does not produce corrosive gases, etc. The carbon monoxide adsorbent obtained by using copper (II) salts or copper (II) oxide is also stable relative to sulfur content in the mixed gas.
