ABSTRACT OF THE DISCLOSURE A reaction vessel for regenerating particulate adsorbents has a bottom outlet and top inlets for admission of the adsorbent to be regenerated by being heated to a regeneration temperature, and for a particulate regenerating material at a temperature above the regeneration temperature. The mixture of the adsorbent with the regenerating material forms a bed in the reaction vessel and is contiuously withdrawn through the outlet so that the bed descends toward the latter and is replenished from above under the formation of a cone at the upper region of the bed. A plurality of tubular baffles coaxially surrounds the inlets which are also coaxial with one another, each of the tubular baffles penetrating into the bed in the region of the cone and retards the flow of the particles of the mixture down the slope of the cone in that the particles must pass underneath the baffle to flow to the next baffle. The bed may be confined between a plurality of axially overlapping spaced tubu- lar guide baffles located in the interior of the reaction vessel with a spacing therefrom. At least one partition may be provided between one of the guide baffles and the vessel, subdividing the chamber between the vessel and the guide baffles into two compart- ments from which gases which develop during the regeneration of the adsorbent are separately exhausted.
