PROBLEM TO BE SOLVED: To reuse a disposed cellulose acylate film as a raw material for activated carbon. SOLUTION: An activated carbon production apparatus 10 has a carbonization device 12 and an activation device 13. The carbonization device 12 has a carbonization furnace 20. The activation device 13 has a rotary kiln 30 and a gas supply source 31. In the carbonization furnace 20, a carbonized film 24 is produced from a waste film 15. The inside of the rotary kiln 30 is heated to 750-950°C using an electric heater 43. A carbon dioxide gas 45 is fed from the gas supply source 31 to the rotary kiln 30. The carbonized film 24 is loaded into the rotary kiln 30 and the carbonized film 24 is activated while being stirred by the rotation of the rotary kiln 30. Through this method, the activated carbon 50 is produced from the carbonized film 24. COPYRIGHT: (C)2008,JPO&INPIT
