ABSTRACT OF THE DISCLOSURE A reactor for the continuous thermal treatment of solids, particularly carbonaceous adsorbents comprises two superimposed fluidizing beds, below them a combustion chamber for receiving a fuel- or oil-air mixture, an intermediate regeneration space be- tween the fluidizing beds and a similar space above the upper fluidizing bed. A gas outlet is provided in the top regeneration space to which also the inlet for the material to be treated leads. The outlet for the treated materials is provided on the intermedi- ate regeneration space. The two spaces are connected by a channel through which the overrun of treated material passes from the upper to the intermediate regeneration space. This channel leads from the upper space through the wall of the reactor to the out- side and revers then through the wall back into the intermediate space. Valve means are provided for regulating the flow in the connecting channel. The reactor is operated by passing a propelling gas from the combustion chamber through the apertured bottoms of the fluidizing beds. The propelling gas may have an excess of 10 to 30% of fuel gas relative to the air and additional air inlet may be provided in the intermediate space as well as an auxiliary burner so as to burn away impurities adhering to the treated material.
