| 摘 要： | 本文研究了经Ｏ２，空气或ＨＮＯ３氧化后，高温下热处理改性的活性炭纤维（ＡＣＦ）在Ｏ２和水蒸气存在下脱除ＳＯ２的能力。结果表明，氧化热处理改性后，ＡＣＦ的脱硫能力都有明显提高，其中Ｏ２改性的ＡＣＦ脱硫活性最高，ＨＮＯ３改性的ＡＣＦ最低，空气改性的ＡＣＦ居中。并对改性ＡＣＦ具有不同脱硫活性的原因进行了分析。ＴＰＤ实验表明，Ｈ２ＳＯ４从Ｏ２改性ＡＣＦ上脱除最容易。

| Abstract: | The removal of SO2 over activated carbon fiber (ACF) modified by oxidation followed by heat-treatment has been investigated in the presence of O2 and H2O. The results indicated that desulfu-rization activity of O2-oxidized ACF which was subsequently heat-treated was much higher than that of HNO3-oxidized ACF heat-treated. The air-oxidized sample heat-treated was intermidiate with de-SO2 activity. The causes of different activities of these samples were analysed. |
