CARBONISATION AND (OR) ACTIVATION OF CARBON MATERIAL Russian patent published in 2013 - IPC C01B31/08 C10B47/30 C10B53/07 F27B7/16 

FIELD: chemistry.

SUBSTANCE: invention relates to a method for carbonisation and activation of carbon material and an externally heated revolving furnace for realising said method. The revolving furnace has an inlet and a discharge side, with an inclination downwards towards the discharge side, annular partition walls lying along the furnace for controlling movement of the material and hoisting boards between the partition walls for mixing the material and parts which raise the material upwards and force the raised material to fall in stages into the lower part of the revolving body. The method involves feeding material into the discharge end of the furnace. The material is fed into the furnace in an atmosphere of water vapour or carbon dioxide, essentially free from oxygen. Temperature which is sufficient for drying or removing the solvent from the material without carbonisation is maintained in the first zone of the furnace. Temperature maintained in the second zone lying downstream from the first zone is sufficient for carbonisation of the material, and the temperature maintained in the third zone lying downstream from the second zone is sufficient for activation of the carbonised material.

EFFECT: obtained activated carbon is in form of granules with low content of fine coal, having both a mesoporous/microporous structure and a highly active surface.
