RECOVERING METHOD OF HIGH-PURITY CARBON MONOXIDE

摘要

PURPOSE:To recover efficiently high-purity CO by substituting the inside of the narrow pores of porous absorbent absorbent adsorbed with CO by means of the absorbed CO. CONSTITUTION:After a mixed gas contg. CO is brought into contact with a porous CO absorbent wherein Cu(I) and Al(III) are deposited on a porous inorganic carrier (e.g. porous alumina) to absorb CO selectively, at least the nonabsorbed gas of the inside of the porous narrow pores of the absorbent is substituted with the absorbed CO.
