Patent number: 4587114Abstract: A solid form adsorbent of carbon monoxide, that is obtained 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 pressure 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 above 60.degree. C. or reducing the partial pressure of carbon monoxide. The carbon monoxide 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 containing the water. Also, the separated carbon monoxide does not contain the vapor of the solvent from the carbon monoxide adsorbent.Type: GrantFiled: March 14, 1983Date of Patent: May 6, 1986Assignee: Hidefumi HiraiInventors: Hidefumi Hirai, Makoto Komiyama, Keiichiro Wada
