PRODUCTION METHOD AND USE METHOD FOR GAS ADSORBENT

摘要

PROBLEM TO BE SOLVED: To provide a method for industrially advantageously producing a porous complex synthesized from copper ions and trimesic acids or their derivatives; and a method for separating and recovering and a method for storing a gas (especially, a methane or carbon dioxide gas) using the complex. SOLUTION: An adsorbent comprising a porous complex is produced by reacting copper ions with trimesic acids or their derivatives in a reaction solvent comprising a mixture of an alcohol and water. This adsorbent can be used for separating and recovering a methane or carbon dioxide gas from a gas mixture containing a methane or carbon dioxide gas by PSA or TSA and for storing a methane or carbon dioxide gas.
