摘　　要：研究了沥青基活性炭纤维 (PACF)的制备条件 ,如活化温度、活化时间对产品收率、比表面积以及对正丁硫醇吸附性能的影响。结果表明 ,单纯的 PACF不能吸附己烷中的正丁硫醇。 PACF负载钴盐后 ,可用于脱除硫醇。用于负载钴盐的 PACF的活化温度对脱除硫醇效果无影响 ,但活化时间必须在 90 min以上 ,才能使硫醇含量降到Pitch based activated carbon fiber(PACF) was made from pitch based carbon fiber through activating at high temperature with H 2O as activating agent. The influence of preparing condition such as activated temperatute and time on the yield, specific surface area and its adsorbent behavior towards n butanethiol(BuSH) were studied. The results show that simple PACF can not remove BUSH from n hexane. Therefore in order to remove BuSH, dispersion of appropriated catalyst such as cobalt is need. Cobalt dispered PACF(PACF Co) can remove BuSH quickly. The activated temperature of PACF using for dispering of cobalt salt don′t affected the results, but the activated time need at least 90 min in order to remove BuSH to below 10 ppm.
