Abstract:
A system for adsorbing and oxidizing gaseous volatile organic compounds comprising a source for a gaseous stream containing volatile organic compounds, a single bed comprised of a carrier having an adsorbent component and an oxidation component, means for passing said source stream at a first velocity and a first bed temperature below the functioning temperature of said oxidation component for a period of time to cause a portion of said volatile organic compounds to be adsorbed onto said adsorbent component, means for passing a gaseous oxidizing stream through said bed at a second velocity substantially less than said first velocity, and a heater for heating said gaseous oxidizing stream at said second velocity to increase the temperature in said bed to a second temperature to desorb adsorbed volatile organic compounds and initiate oxidation of the VOC's by said oxidation component.
