Abstract
A method for removing volatile organic compounds (VOCs) from an effluent or exhaust stream produced by an industrial or commercial process that allows for both adsorption and catalytic destruction of the VOCs. The method utilizes a bed containing both adsorbent material and catalytic material, either as an admixture or as separate layers of the two materials. During the preferred mode of operation, one section of the bed collects VOCs from the effluent while simultaneously, in another section of the bed, collected VOCs are destroyed and the bed material is regenerated. This process can continuously eliminate VOCs from an effluent without interruption by rotating the bed through the adsorption and regeneration zones or by rotary feeding of the effluent and an oxygen containing gas to different portions of the bed.
