Abstract
An activated carbon producing system includes a carbonizer for carbonizing cellulose triacetate as cellulose acylate to create carbonized material. A pulverizer pulverizes the carbonized material to obtain granules. An activation device activates the granules to create activated carbon. The activated carbon producing system includes a dispenser for supplying the cellulose triacetate at a plural number of times. A heating furnace is operated at each time after the dispenser operates, for thermally decomposing the cellulose triacetate from the dispenser, to obtain the carbonized material by carbonization. The pulverizer pulverizes the carbonized material in a size equal to or more than 2 mm and equal to or less than 20 mm. Temperature of the heating furnace is equal to or higher than 300 deg. C. and equal to or lower than 600 deg. C.
