PURPOSE:To produce the titled adsorbent having excellent adsorption and desorption performance of CO, by dissolving a Cu(I) compound in a solvent and contacting the solution with heated silica and/or alumina carrier under a specific condition. CONSTITUTION:A Cu(I) compound (e.g. cuprous chloride) is dissolved in a solvent such as water, hydrochloric acid, ammonia water, etc. The solution is optionally heated at 40-100 deg.C and sprayed to a silica and/or alumina carrier having particle diameter of 1-7mm and preliminarily heated at 50-150 deg.C. The saturated absorptivity of the solution to the carrier is adjusted to + or -10% during the above adsorption process. The adsorbed solution is dried by heating in an inert gas atmosphere and, if necessary, heated in an inert gas or reducing gas atmosphere at 100-300 deg.C to obtain an adsorbent for the separation and recovery of CO and containing 0.5-8m-mol/g of supported Cu(I) compound. |
