Abstract
A method for adsorbing and oxidizing VOC's in the same bed, thus reducing the size of or even eliminating the need for a catalytic or thermal oxidation unit at the end of the system. In this system, a catalyst is intimately interspersed with the adsorbent material. The catalyst oxidizes VOC's released during desorption when it reaches the 'light off temperature,' that is, the catalyst temperature necessary for oxidation to begin. As VOC's are desorbed, they are combusted by the catalyst in the same bed and also by their combustion, heat the bed to aid in the desorption of VOC's elsewhere in the bed.
