摘　　要：研究了沥青不熔化纤维的碳化、活化规律，分析讨论了各因素对沥青基活性碳纤维成型过程的影响。结果表明，要获得较高比表面积的活性碳纤维，不熔化纤维氧化增重应适当，碳化温度宜在７５０～８００℃，获得较大无定形碳的碳纤维。活化温度、活化时间、活化剂浓度也为影响沥青基活性碳纤维比表面积的主要因素。The carbonization the activation of stabilized Btch fitwrs are studied and some factrca influenced upon forming process of activated carbon fibers are also disscused in this paper.The results show that a substantial amount of oxidation increment of stabilized Pitch fibers and carbonization temperature in 750￣ 800℃ of Pitch fibers will help obtaining higher specific surface area of actived fibers and carbon fibers containing larger amount of araphitic carbon.Activation temperature,activation time,activation agent concentration are main factors influenced upon specific surface area of Pitch-based actived carbon fibers.
