煤焦油沥青基炭纤维（ＣＰＣＦ）价格低廉、含炭量高、易于活化，是制备纤维状活性炭（ＣＰＡＣＦ）的优良原料．本文讨论了ＣＰＣＦ的抗拉强度和活化条件对ＣＰＡＣＦ比表面积的影响，并同石油系沥青基炭纤维（ＰＰＣＦ）进行了比较．考察了不同比表面积的ＣＰＡＣＦ、ＰＰＡＣＦ和商品用颗粒活性炭（ＡＣ）对０．１ｍｏｌ／Ｌ碘溶液、０．００５ｍｏｌ／Ｌ亚甲兰溶液和２９３Ｋ下三氯甲烷饱和蒸汽的吸附性能，及以上三样品在２９３Ｋ饱和苯蒸汽下的再生性能。结果表明：无论ＣＰＡＣＦ还是ＰＰＡＣＦ，其活化反应与微晶排列相关，两者具有相似的孔结构．相同比表面积时，ＰＰＡＣＦ的性能优于ＣＰＡＣＦ，这是由于前者表面含更多的含氧官能团，同颗粒活性炭（ＡＣ）相比，ＰＰＡＣＦ和ＣＰＡＣＦ吸脱附速率快，吸附容量大，这同它们的结构差异相关。
Coal tar pitch-based carbon fiber (CPCF) low price, high carbon content, easy activation, is the preparation of fibrous activated carbon (CPACF) excellent raw materials. This article discusses the impact of CPCF tensile strength and activation conditions on the CPACF specific surface area, and compared with petroleum-based pitch-based carbon fiber (PPCF). The adsorption performance of CPACF, PPACF and granular activated carbon (AC) with different specific surface area on 0.1mol / L iodine solution, 0.005mol / L methylene blue solution and trichloromethane saturated steam at 293K were investigated. Regeneration performance of sample under 293K saturated benzene vapor. The results show that both CPACF and PPACF have the same pore structure as the activation reaction and the microcrystalline arrangement. The same specific surface area, PPACF performance is better than CPACF, which is due to the former containing more oxygen-containing functional groups, compared with granular activated carbon (AC), PPACF and CPACF adsorption and absorption rate, adsorption capacity, Related to the structural differences.
