Abstract: At least two horizontal perforated plates are vertically spaced. A powdered or granular carbonaceous substance is fed onto the lowermost of the perforated plates and, at the same time, a hot activating gas is introduced upwardly from below the lowermost horizontal perforated plate so that the activated portion of said powdered or granular carbonaceous substance is allowed to ascend to and form a fluidized bed on successively higher perforated plates. The activated carbon of the highest grade of quality collects on the uppermost perforated plate as the final product. The manufacture of activated carbon described above is accomplished by use of an apparatus which comprises, in combination, at least two horizontal perforated plates having holes of a fixed diameter distributed at a fixed rate, two inlets disposed at a lower part of the apparatus, one for admitting the carbonaceous substance and the other for permitting introduction of the activating gas, and two outlets disposed at an upper part of the apparatus, one for discharging the activated carbon as the product and the other for releasing the spent activating gas.

Abstract: A process for the dry distillation of used rubber in a fluidized bed-forming oven comprises heating used rubber under agitation in the presence of solid particles to temperatures sufficient to make the rubber pulverized and further heating the thus-obtained rubber particles to temperatures sufficient to pyrolyze the rubber particles while forming a fluidized bed thereof and burning a part thereof in the stream of an oxygen-containing fluidizing gas.
