<P>PROBLEM TO BE SOLVED: To provide a method for producing activated carbon having a large specific surface area easily and inexpensively by using an activated carbon source material having an optically anisotropic texture. <P>SOLUTION: The activated carbon is produced by stabilization treatment of the activated carbon source material having the optically anisotropic texture of 50% or more and by oxygen cross-link polymerization to have oxygen content of 15-35 wt.% and then treated with steam for activation. The activated carbon has a specific surface area of 500 m<SP>2</SP>/g or more by a BET method, a mean pore radius of 0.8-1.5 nm, a pore volume of 0.2-1.5 mL/g and true specific gravity of 1.7 or more. <P>COPYRIGHT: (C)2003,JPO |
