MODE AND INSTALLATION FOR RECEIVING ACTIVATED CARBON Russian patent published in 2008 - IPC C10B49/04 C01B31/08 

FIELD: invention refers to field of reprocessing of solid carbon containing materials.

SUBSTANCE: In reactor 1 provided with in-series located zone of heating 2, zone of carbonization 3 and zone of activation 4, they load raw materials through pipeline 5. Raw materials are transferred through all zones along screw channel 15 with gradually diminishing axial component of speed due to rotation of inner shell 12. Warmth carrier is received in fuel burning chamber 7 and directed into boiler for utilization. External supply of heat is executed with flow of warmth carrier through ring channel 14 formed with inner cylinder surface of body 10 and external shell 11. Simultaneously they execute inner supply of warmth with flow of warmth carrier through cylindrical channel 16, formed with inner shell 12. Warmth carrier is received in fuel burning chamber 7 and is directed in boiler 6 for utilization, where part of warmth is spent on receiving of activating agent-heated water steam. In heating zone 2 raw materials are heated till temperature of carbonization - no less then 650°C. In zone of activation 4 they execute activation at temperature no less then 750°C of carbonizate-solid product received in zone of carbonization 3. Received hot activated coal is fed along pipeline 36 into cooler 8.

EFFECT: increases quality of received activated carbon and energy effectiveness of technological process executed in uninterrupted regime.
