摘要： PROBLEM TO BE SOLVED: To provide a porous charcoal which has a high specific surface area and a porous structure suitable for an electric double layer capacitor and is produced by using an organic material to be processed, e.g. a woody material, as a raw material; and its production method.
SOLUTION: A porous charcoal production apparatus having a drying furnace and a carbonization furnace continuously performing carbonization and activation is used. A carbonization treatment and an activation treatment are continuously performed by introducing superheated steam with an entrance temperature of 750-950°C into the carbonization furnace for a processing object, by rotating a rotation paddle with a frequency of 3-6 rotations per minute and with a peripheral speed of 0.035-0.07 m/s, and keeping a raw material feeding rate of 0.2-0.5 kg/h/liter per a raw material processing volume in the carbonization furnace. Thus, provided is a porous charcoal, which has a total specific surface area of 600 m
2 /g or more and a pore distribution structure wherein the outside specific surface area accounts for 30-75% of the total specific surface area.
