REGENERATION OF A FIXED-BED OF ACTIVATED CARBON ADSORBED ORGANIC VAPOR BY USING HOT NITROGEN PURGE

Thermal regeneration of activated carbon adsorbed acetone or acetaldehyde was studied experimentally and theoretically by hot nitrogen purging through a fixed bed. A linear driving force mass transfer model was proposed and found to well simulate the experimental data. The parameters investigated included total system pressure, initial bed loading, and regeneration temperature. The temperature of purge gas was programmed by some different modes. The adsorption isotherms were determined by a static manometric method.
