PURPOSE:To provide fibrous activated carbon having high performance, high crystallinity and high specific surface area. CONSTITUTION:The objective fibrous activated carbon can be obtained by melt spinning of pitch containing >=50vol.% of optically anisotropic phase. This activated carbon has: specific surface area determined by BET technique: >=1000m<2>/g and hydrogen atom content: <=0.5wt.%. Specifically, this carbon fiber can be produced by the following process: the above-mentioned pitch is put to melt spinning and then baked into baked fibers, which are, in turn, incorporated with a chemical followed by reaction at 300 1800 deg.C. |
