A gas separation device includes an inner conduit, and a concentric outer conduit. An electrically conductive filter media, preferably a carbon fiber composite molecular sieve, is provided in the annular space between the inner conduit and the outer conduit. Gas flows through the inner conduit and the annular space between the inner conduit and the outer conduit, so as to contact the filter media. The filter media preferentially adsorbs at least one constituent of the gas stream. The filter media is regenerated by causing an electric current to flow through the filter media. The inner conduit and outer conduit are preferably electrically conductive whereby the regeneration of the filter media can be electrically stimulated. The invention is particularly useful for the removal of CO2 from the exhaust gases of fossil-fueled power plants.

1. A gas separation device, comprising:an electrically conductive inner conduit defining an inner flow path; an electrically conductive outer conduit concentric with said inner conduit and defining an annular flow path; an electrically conductive filter media, said electrically conductive filter media being at least in part disposed in the annular flow path between the inner conduit and the outer conduit; a regeneration circuit electrically connecting said inner conduit, outer conduit, and electrically conductive filter media, whereby a regenerating current can be passed through said filter media to regenerate said filter media and desorb adsorbate gas species.
