ACTIVATED CARBON FOR ADSORBING ACIDIC GAS AND PRODUCTION THEREOF

摘要

PROBLEM TO BE SOLVED: To efficiently keep high removing ratio over a long period of time in acidic gas. SOLUTION: Activated carbon carbonated and activated in the presence of an alkali chemical agent and having an alkali metal component and/or an alkaline earth metal component supported thereon contains 1-30wt.% of the alkali metal component and/or the alkaline earth metal component in terms of metal per the total quantity. This activated carbon is produced by uniformly mixing an activated carbon precursor org. substance and an alkali metal compd. and/or an alkaline earth metal compd. and subsequently carbonating and activating the resulting mixture by baking.
