Abstract
Abstract An adsorption device for gas separation with an adsorbent includes a thermally insulated container. Adsorber tubes with a given length are vertically disposed in the container for receiving adsorbent. A heating device is adjacent the adsorber tubes. Cooling tubes are disposed alongside the adsorber tubes and extend over substantially all of the given length for receiving coolant. A gas circulation device in the container generates a gas flow encompassing the heating device, the cooling tubes and all of the given length of the adsorber tubes.
