摘要
以沥青基炭纤维(PCF)为原料,H2O、CO2为活化剂,采用直接活化和炭化-活化两种不同工艺制备活性炭纤维。经对比发现,采用炭化-活化法制备的沥青基活性炭纤维(PACF)在比表面积、吸附性能和收率等方面均比直接活化法制备的PACF有明显提高。
Pitch-based activated carbon fiber(PACF) have been prepared by activating pitch-based carbon fiber (PCF) that carbonized or not with H2O and CO2. The results revealed that the specific surface area. absorbability and yield of PACF carbonized all above the PACF carbonized one time.
