ACTIVATED CARBON, PROCESS FOR PRODUCING THE SAME, AND PRODUCTION APPARATUS

摘要

An activated carbon that produced from an organic treatment object, such as a woody material, as a raw material, has a large specific surface area and a pore structure suitable for electric double layer capacitor; and a process for producing the same. There is provided an activated carbon produced by subjecting a treatment object composed mainly of a woody material to carbonization treatment and activation treatment continuously performed in an atmosphere of superheated steam, which activated carbon has a total specific surface area of 600 m²/g or greater and such a pore distribution structure that an external specific surface area occupies 20 to 75% of the total specific surface area.
