Abstract
A fluidized-bed activation furnace for activated carbon is disclosed. The furnace is provided with a central hollow pillar having an outlet for discharging activated carbon granules at the upper portion thereof, a bowl-shaped cap covering the top portion of the central hollow pillar and a perforated plate fixed to the outer periphery of the central hollow pillar below the outlet for discharging activated carbon granules. After the granules of carbon are activated while a fluidized-bed is formed of the activated carbon granules, the substantially whole amount of granular activated carbon is discharged in a short time maintaining a high temperature.
