摘要
本文研究了经O_2,空气或HNO_3氧化后,高温下热处理改性的活性炭纤维（Acti-vated Carbon Fiber,ACF）在O_2和水蒸气存在下脱除SO_2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O_2改性的ACF脱硫活性最高,HNO_3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。
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.
