ABSTRACT:
Disclosed is a composite adsorbent consisting of a molded body of homogeneous mixture comprising powdery active carbon and hydrous alumina of the pseudoboehmite type. This composite adsorbent has high mechanical strength and abrasion resistance. This composite adsorbent is excellent in the capacity of adsorbing organic components such as gasoline, and the desorption of the adsorbed components can be easily accomplished at a high desorption ratio. These excellent capacities are retained even if the adsorption-desorption cycle is repeated. Accordingly, this composite adsorbent is especially valuable as the adsorbent for an automobile canister.
