中文摘要：

应用聚丙烯腈基活性碳纤维（PANACF）对低浓度SO2（200×10^-6）进行吸附氧化试验。通过改变活性碳纤维量、SO2浓度、氧浓度及水蒸气浓度，观察PAN—ACF脱除低浓度SO2能力的变化规律。实验结果表明，PAN—ACF对低浓度SO2有很好的脱除作用，随着活性碳纤维量、氧浓度及水蒸气浓度的增加，PANACF脱除低浓度SO2的能力增强。

英文摘要：

Adsorption and conversion of low concentration SO2 by polyacrylonitrile-based activated carbon fiber （PAN-ACF） is experimentally studied. The concentration of SO2, O2 and water vapor and the mass of PAN-ACF, which have influence on desulfuration, are observed in this experiment, It is found that PAN-ACF removes low concentration SO2 very well. Accompanied by more mass of PAN-ACF, higher concentration of O2 or water vapor, PAN-ACF shows better ability of desulfuration,
