Electrical Swing Adsorption is a version of temperature swing adsorption in which the adsorbent is regenerated by Joule heating. To accomplish this feature, the adsorbent must be a continuous, electrically conducting member, which usually restricts the application to activated carbon samples. Unfortunately, the CO2 adsorption capacity and selectivity of activated carbon is not as good as silica-alumina materials such as zeolites. In addition, the low resistance of activated carbon samples often means that the dominant heat generation occurs at the contact resistance between the electrodes and the sample, depriving the bulk sample of temperature increase. Use of the silica-alumina materials t..View full abstract
