An apparatus and a method for purifying the air used in cryogenic air separation are described, which are capable of effectively removing nitrogen oxides and/or hydrocarbons. The apparatus comprises an adsorber comprising an adsorption cylinder that has a first adsorbing layer and a second adsorbing layer therein. The first adsorbing layer is composed of a first adsorbent capable of selectively adsorbing water in the air. The second adsorbing layer is composed of a second adsorbent capable of selectively adsorbing nitrogen oxide and/or hydrocarbon in the air passing the first adsorbing layer, wherein the second adsorbent comprises an X zeolite containing magnesium ion as an ion-exchangeable cation.

A carbonaceous material for an electrical double layer capacitor is produced by performing a halogenation treatment step wherein a halogenated dry-distilled charcoal is obtained by bringing a dry-distilled charcoal into contact with a halogen gas; a molding treatment step of adding a binding agent to the halogenated dry-distilled charcoal to form a molded article; and a dehalogenation treatment step wherein a part or all of the halogen in the molded article is eliminated. The carbonaceous material for an electrical double layer capacitor obtained by this method is impregnated with sulfuric acid to form a carbon electrode for an electrical double layer capacitor. This electrode is used to form an electrical double layer capacitor.
