摘　　要：本文研究PAN-ACF钢主要结构参数,探讨了ACF对SO_2的物理吸附、脱附性能以及传质机理,得出传质过程为内扩散控制,并计算出扩散系数D值约为活性炭D值的50～170倍。In this paper, the main structural parameters of PAN-ACF were investigated. The physical adsorption, desorption properties and mechanism of mass transfer of SO_2 by PAN-ACF were studied. The expermental results show that the mass transfer process is internal diffusion control. The diffusion coefficient of PAN-ACF is 50～170 times of that of activated carbon.
