Abstract:
An adsorption and recovery method for an adsorption unit including at least one activated carbon fiber element, the method comprising steps of:heating an activated carbon fiber element through electrical current flow, the activated carbon fiber element being configured to exhibit sufficient electrical resistance for heating; directing a gas flow to penetrate the activated carbon fiber element when the activated carbon fiber element has been heated to selectively adsorb at least one constituent of the gas flow; desorbing an adsorbed constituent by controlling activated carbon fiber temperature through electrical current flow to a temperature for desorption in the presence of an inert gas flow; controlling the inert gas flow to permit condensation of a desorbed constituent on an inner surface of an enclosure housing the activated carbon fiber elements; recovering condensate that comprises desorbed constituents in liquid phase from the enclosure.
