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...
A process for regenerating spent carbonaceous adsorbent particles which have been used to effect dry desulfurization of a sulfur oxide-containing exhaust gas so that said spent carbonaceous adsorbent particles contain adsorbed sulfur oxide material, which comprises the steps of: mixing said spent carbonaceous adsorbent particles with an inert purging gas to form a first mixture of said spent carbonaceous adsorbent particles and said inert purging gas; then feeding said first mixture downwardly through a heating zone and therein heating said first mixture...
