Abstract

Activated carbon having adsorbed materials thereon is regenerated by passing a mixture of gases and/or vapors capable of exothermically reacting through the bed. The heat of reaction liberated by the reaction heats the carbon bed sufficiently to permit removal of the adsorbed materials thereon. The bed may then be further purged with an inert gas to complete the removal of the adsorbed materials.
