| 摘 要： | 以水为活化剂，山楂核渣为前驱体，采用普通活化和超临界活化法来制备活性炭，并用77K氮气吸附表征所获得样品的孔结构。结果表明，山楂核渣可以用来制备活性炭，所得活性炭以微孔为主。山楂核渣也可以采用超临界水进行活化，但是效果并不十分明显。

| Abstract: | Activated carbons were prepared from haw-stones residue using tradi ti onal steam activation method and super-critical water activation method. The po re structure of the obtained activated carbons was characterized by N2 adsorptio n technique. The influences of two different activation processes on the evoluti on of pore structure of the obtained activated carbon were compared. The results show that micropores dominate in activated carbons derived from haw-stones residue. Haw-stones residue can be activated in super-critical water but no significant effect is observed. |
