| 摘 要： | 通过使用氨水作活化剂对沥青基炭纤维进行活化，制香了表面富含氮元素的活性纤维，元素分析和XPS均证实此种活化方法可在活性炭纤维上引入停含炭纤维上引入含氮宫能团，所得活性炭纤维在H2O和O2存在下脱除模拟烟气中SO2的活性显著高于用常规方法化（如水蒸汽）制香的活性炭纤维，也高于含氮的聚丙烯腈基活性炭纤维，对引入到ACF表面的含氮官能团的种类及其在脱硫过程中所起的作用进行了分析。

| Abstract: | Carbon fibers from ethylene tar pitch were converted to nitrogen containing active carbon fibers (ACFs) by ammonia water activation instead of steam activation. The introduction of nitrogen containing functional groups in ACFs was indentified by elemental analysis and XPS. The activity of ACFs from ammonia water activation for SO\-2 removal in the presence of O\-2 and H\-2O is markedly higher than that of ACFs from steam activation, and is also higher than that of PAN ACF .The type and function of nitrogen containing groups during desulfurization were discussed in detail. |
