The method enabled as a result of the development of the aforementioned apparatus, i.e., a method for removing VOC's from an exhaust stream, involves two essential steps: (1) causing exhaust gases from an exhaust gas stream to flow through an adsorber structure and an oxidizer while adsorbing an amount of VOC's; and, (2) heating the oxidizer to its lightoff temperature and desorbing the adsorbed VOC's and thereafter flowing the desorbed compounds through the oxidizer whereupon they are oxidized. One particular embodiment involves two essential steps: (1) flowing VOC-containing exhaust gases through an adsorber structure having an activated carbon phase and an electrically heatable catalyzed structure while adsorbing an amount of VOC's; and, (2) heating the catalyzed structure to its lightoff temperature, desorbing the adsorbed VOC's and thereafter flowing the desorbed compounds through the catalyzed structure whereupon the desorbed VOC's are oxidized.
