ADSORBING TREATMENT MEMBER AND ADSORBING TREATMENT APPARATUS AND METHOD USING THE SAME

摘要

PROBLEM TO BE SOLVED: To make various components to be adsorbed efficiently adsorbed even under any temp. environment when the components to be adsorbed (especially, a carbonyl group-containing compd.) in gas to be treated is adsorbed and to suppress the change of adsorbing capacity with the elapse of time. SOLUTION: A sheet-like filter member 1 contains a chemical adsorbent 12 having an adsorbing compd. reacting with a conbonyl group-containing compound in gas to be treated in the presence of moisture and H-type zeolite absorbing moisture and supporting the adsorbing compd. and a physical adsorbent 13 having activated carbon in a mixed state within the single space demarcated by two air permeable members 16, 16.
