Abstract
An adsorption apparatus provided with a means for physically separating and removing moisture, such as a cyclone type separating means or metal honeycomb or other cooling and condensing means, at the upstream side of a hydrocarbon adsorbent so as to enable the hydrocarbons exhausted at the time of engine start-up to be efficiently adsorbed by eliminating the decline in the adsorption power caused by the moisture in the exhaust gas.
