| 摘 要： | 由添加二茂铁和不添加二茂铁沥青球制得了两类沥青基球状活性炭，比较了它们微孔结构及孔容等的异同点，研究了铁的存在对活性炭微孔形成过程的影响，考察了活化时间及活化温度对含铁沥青基球状活性炭微孔形成的影响。结果表明，铁的存在对活性炭的微孔分布没有明显影响，但却使活性炭微孔的比表面积和孔容有所下降。

| Abstract: | The microporous texture of pitch-based spherical activated carbon(PSAC)containing iron and without iron was studied in order to investigate the effect of iron on the formation of micropore.It was showed that iron had no obvious influence on the distribution of micropore,while it made the specific surface area and pore volume of micropore decrease slightly. |
