Angelo, J F

A process is disclosed for carbonizing and then activating carbonaceous materials in a continuous process. It is performed by an apparatus consisting of an elongated, slightly inclined rotary retort into the higher end of which the material is deposited and from the lower end of which the product is removed, the material moving therethrough in the form of a tumbling bed, a system for introducing air in independently regulatable amounts into each of a series of longitudinally spaced zones of the retort, except a final zone closest to its lower end, in such a manner that contact of the air with the material bed is delayed for a substantial time after the air enters the retort, and a system for introducing superheated steam into the final retort zone as an oxidizing agent in such a manner as to immediately engage and thoroughly intermix with the material bed. Provision is also made for introducing air, rather than steam, into the final retort zone, in the event carbonization, but not activation, may be desired.
