PROBLEM TO BE SOLVED: To provide a process of producing an activated carbon which is simple and provides high productivity and thermal energy saving, in which finely divided raw material of the activate carbon is used. SOLUTION: The process of producing an activated carbon uses an apparatus in which a cylindrical rotator penetrates horizontally and rotatably a heating furnace which is fixed or rotatable, scraping vanes are provided inside the cylindrical rotator with an oblique angle to the rotating axis direction, a screw feeder is provided at the charging end of the cylindrical rotator coaxially with some play. The process comprises the steps of charging raw material for the activated carbon into the screw feeder, carbonizing and activating the material sequentially in the cylindrical rotator heated by the one heating furnace, and collecting the activated carbon product from the other end of the cylindrical rotator. |
