Abstract

An apparatus for performing the method of the invention for the thermal regeneration of contaminated particulate adsorption agents in a fluidized state includes a regeneration chamber which has separate first and second zones for the thermal treatment of the adsorption agents in a fluidized state. A first inlet is provided for admitting contaminated adsorption agents into the first zone and a separate second inlet is provided for admitting contaminated adsorption agents into the second zone. A first outlet is provided for removing regenerated adsorption agents from the first zone whereas a separate second outlet is provided for removing regenerated adsorption agents from the second zone. Means for fluidizing and thermally treating the contaminated adsorption agents so as to regenerate the same includes a combustion chamber arranged to supply hot fluidizing gases to both of the treatment zones. A gas outlet in the regeneration chamber serves to exhaust the fluidizing gases from both of the treatment zones.
