ADSORBENT FOR CARBON MONOXIDE

摘要

PURPOSE:To obtain the titled adsorbent free from the deterioration of performance even if repeating adsorption and desorption by using polystyrene resin having amino group and cuprous chiocyanate as constitutional components. CONSTITUTION:Cuprous chiocyanate and a solvent (i.e. acetonitrile or the like) are mixed and stirred. Then dried polystyrene resin having amino group is added thereto in 0.1-30 preferably 0.5-3 molar ratio for cuprous thiocyanate and stirred. The mixture is heated under reduced pressure to sufficiently distill the solvent and an adsorbent being a solid for carbon monoxide is obtained. The obtained adsorbent quickly adsorbs carbon monoxide under ordinary temp. and ordinary pressure and adsorbed carbon monoxide can be desorbed by heating this adsorbent or decompressing it or reducing the partial pressure of carbon monoxide. Therefore carbon monoxide can be easily separated from a gaseous mixture. Furthermore the performance of this adsorbent is not deteriorated even if repeating adsorption and desorption.
