ADSORBENT FOR SEPARATING AND RECOVERING CO, ITS PRODUCTION AND METHOD FOR SEPARATING AND RECOVERING HIGH-PURITY CO BY USING ITS ADSORBENT

摘要

PURPOSE:To efficiently separate and recover high-purity CO by using a carrier consisting of silica and/or alumina as the core, forming an org. carbide layer having activity on the surface of the core to obtain a composite carrier, depositing a copper compd. on the composite carrier to form an adsorbent and using the adsorbent. CONSTITUTION:A carrier consisting of silica and/or alumina is used as the core and an org. carbide layer having activity is formed on the surface to obtain a composite carrier. A soln. of a copper compd. in a solvent or the liq. dispersion is brought into contact with the composite carrier, then the solvent is removed, the obtained material is heated in an inert gas or a reducing gas atmosphere to deposit the copper compd. and the adsorbent is obtained. The adsorbent is used and high-purity CO is separated and recovered from a mixed gas contg. CO by a pressure-fluctuation adsorptive separation method and/or a temp. -fluctuation adsorptive separation method.
