Abstract

Pitch based activated carbon fiber was produced by different activation parameters from oxidized fiber of isotropic pitch, and the effect of parameters on the specific surface area and pore structure (volume, pore size and its distribution) was discussed. The results indicated that pore diameter became larger and its distribution became wider with the increase of activation temperatures from 850 to 950?℃. Although the final activation temperature(900℃) was kept unchanged, pore structure varied with steam -inlet temperature
