SEPARATION OF CARBON MONOXIDE BY ADSORPTION

PURPOSE:To separate CO from a gaseous mixture contg. CO, CO2, CH4, N2, etc. by adsorption by treating the gaseous mixture with a solid adsorbent consisting of a copper (II) salt and activated carbon. CONSTITUTION:Activated carbon and copper (II) formate, copper (II) nitrate, copper (II) chloride or...

Summary:PURPOSE:To separate CO from a gaseous mixture contg. CO, CO2, CH4, N2, etc. by adsorption by treating the gaseous mixture with a solid adsorbent consisting of a copper (II) salt and activated carbon. CONSTITUTION:Activated carbon and copper (II) formate, copper (II) nitrate, copper (II) chloride or other copper (II) salt are mixed in 1.0-30 ratio and stirred in a solvent such as water, or methanol, and the solvent is removed under reduced pressure or by other method. The resulting solid is used as a CO adsorbent. The solid may be heated to 100-150 deg.C in a reducing gas such as H2. A gaseous mixture contg. CO, CO2, CH4, H2, moisture, etc. is passed through the adsorbent to allow CO to be adsorbed on the adsorbent. The adsorbed CO is easily released by heating to >=60 deg.C or under reduced pressure. Thus, CO is separated and recovered from the gaseous mixture in a high yield.
