摘要：

Recently there has been an increase in interest in the production, properties and applications of activated carbon fibers (ACF) produced from pitch precursors. These fibers offer a number of advantages and because of their novel properties may be more suitable in certain applications than conventional granular and powdered activated carbons. The isotropic nature of pitch-based fibers makes it possible to create high specific surface areas in the region of 700-2000 m2/g; because diffusion limitations are minimal, the fibers exhibit very high rates of adsorption and desorption, and they may be produced in a wide variety of woven and non-woven forms. The adsorptive properties of these fibers are not as well-studied as those of other commercial activated carbons. This paper describes the synthesis and pore structure characterization of activated Ashland petroleum pitch carbon fibers, by gas adsorption and mercury porosimetry.
