通过炭化、活化,对具有一定孔隙的市售活性炭纤维进行孔结构调控,实验结果表明:炭化和活化均能有效提高活性炭纤维的比表面积和吸附能力。在活化温度为820℃,活化时间为120min时,ACF比表面积由原来的673m2/g增大为2685m2/g,而微孔比例由99.8%减小为71.9%,苯吸附率则由33.0%增大至146.2%。 Through the carbonization and activation, the pore structure of commercially available activated carbon fibers with certain pores was controlled. The experimental results show that both carbonization and activation can effectively improve the specific surface area and adsorption capacity of activated carbon fibers. When the activation temperature is 820 ℃ and the activation time is 120min, the specific surface area of ​​ACF increases from 673m2 / g to 2685m2 / g, while the micropore ratio decreases from 99.8% to 71.9% and the benzene adsorption rate increases from 33.0% As large as 146.2%.
