HONEYCOMB ADSORBENT, METHOD OF MANUFACTURING THE HONEYCOMB ADSORBENT AND CANISTER

A cylindrical column-shaped honeycomb adsorbent has a plurality of cell passages extending along an axial direction of the honeycomb adsorbent. The plurality of cell passages are configured so that a pitch of adjacent cell passages is within a range of 1.5 mm ¼ 1.8 mm, and so that a thickness of a...

Beschreibung
Zusammenfassung:	A cylindrical column-shaped honeycomb adsorbent has a plurality of cell passages extending along an axial direction of the honeycomb adsorbent. The plurality of cell passages are configured so that a pitch of adjacent cell passages is within a range of 1.5 mm ¼ 1.8 mm, and so that a thickness of a wall between the cell passages is within a range of 0.45 mm ¼ 0.60 mm. With this configuration, the honeycomb adsorbent exhibits BWC (Butane Working Capacity) of 6.5 g/dL or greater. By mixing fibrous meltable core melting away during baking, the honeycomb adsorbent has macropores configured to have a volume of 0.15 mL/g ¼ 0.35 mL/g with respect to an overall weight of the honeycomb adsorbent and metal oxide particles having a proportion of weight of 150 ¼ 250 % with respect to the activated carbon.
