| 摘 要： | 以沥青基炭纤维（PCF）为原料,以H2O、CO2为活化剂,以氨盐混合液为浸渍剂,对不同活化条件制得的ACF进行了比较。结果证明：H2O与CO2复合活化的效果优于单一活化剂活化;活化温度的提高有利于沥青基活性炭纤维（PACF）比表面积的增加,表面处理对活化效果有显著影响。

| Abstract: | Pitch based activated carbon fibers (PACF) have been prepared by activating pitch based carbon fiber (PCF) with H 2O and CO 2 as activating agent and ammonium salt mixture as impregnant. The results reveal that the method!using H 2O and CO 2 as mixed activating agent is much better than that using single activating agent. Higher activation temperature is beneficial to the increase of the BET surface area of PAFC. It is obvious that the surface treatment is of great help to the effective activation of PACF. |
