    Abstract: A method for producing an activated carbon material, wherein the method comprises a step of thermally treating coal-based pitch at two temperature ranges of 400null C. to 600null C. and 600null C. to 900null C.; and a step of mixing the thus obtained carbonaceous material with an alkali metal compound and effecting activation thereof at 600null C. to 900null C., and an activated carbon material obtained by the method. When the activated carbon material of the present invention is used a polarizable electrode material of an electric double layer capacitor, high capacitance per electrode is attained without application of excessive voltage. By adding fibrous material to a coal-based pitch during activation expansion of an alkali molten liquid can be suppressed and productivity can be drastically improved. Furthermore, employment of an fibrous carbon material which is excellent in conductivity as a fibrous material, carbon fiber is melt-bonded on the surface of the activated carbon material, which enables production of a polarizable electrode exhibiting excellent charge/discharge characteristics at high current density.

    Abstract: Nitrogen is fed into a sealed container (18) to expel oxygen (step 1) and, in such a state, the inside temperature of the container (18) is incrementally raised step by a heater built into the container (18). In sequential steps 2 through 5, Water content, chlorine, and high-molecular gases are extracted. Reusable carbon and metal remain in the container (18) in step 6, or when left standing for a prescribed time or more. Gases extracted in steps 2 to 5 can be liquefied for recycling. No carbon dioxide or dioxins are produced because heating is performed in an oxygen-free atmosphere. A furnace is not required because the heater is installed in the container (18), and treatment efficiency is high. A space-saving, energy-efficient, and low-cost treatment system, by which carbon (e.g., inert carbon), metals, and the like can be recovered in a reusable state without producing carbon dioxide or dioxins, is obtained. The obtained inert carbon can be subjected to an activation treatment to continuously mass-produce carbon nanotubes and activated carbon.
