| 摘 要： | 以神东煤为原料,KOH为活化剂制备高比表面积活性炭,分别考察碱煤比、活化温度和活化时间对活性炭孔结构的影响,并用于CH4和H2的吸附与分离.结果发现,制得活性炭的比表面积和孔容随碱煤比和活化时间的增加分别呈增加和先增加后减小的趋势,但比表面积受活化温度影响不大,孔容随活化温度升高而增加;适合于CH4和H2分离的活性炭的最佳制备条件为:碱煤比为5,活化温度800℃,活化时间为90min.

| Abstract: | Shendong coal was activated by KOH for preparation of high surface area activated carbons as adsorbent to separate CH4 and H2.The effects of different preparation variables,including the KOH/coal ratio,activation temperature and time,on the final porous texture of activated carbon were discussed.The results showed that the surface area and pore volume of prepared activated carbon increase with the increase of KOH/coal.The surface area and pore vo-lume reach maximum with activation time and then decrease.The... |
