Process for regeneration of carbonaceous adsorbent for use in desulfurization of exhaust gas

摘要

The present invention is to provide a process for the regeneration of carbonaceous adsorbent for use in desulfurization which comprises flowing spent carbonaceous adsorbent, which has been used in the dry desulfurization of a sulfur oxide-containing exhaust gas, together with an inert gas downwardly into a heating zone; heating said spent adsorbent to regeneration temperatures by bringing a heating gas into contact with the spent adsorbent and inert gas indirectly in said heating zone so that the spent adsorbent is regenerated as well as matters desorbed from the adsorbent are purged therefrom by the action of said inert gas; and separating the thus regenerated adsorbent from the inert gas accompanying the desorbed matters in a separating zone located under the heating zone.
