摘　　要：论述活性炭纤维(ACF)优越的空孔结构特性及催化改性处理对其气体吸附性能的影响,指出改性后ACF表面引入的含氮和含氧官能团有利于在低温下综合吸附烟气中SO2、NO、Hg等污染物,特别对SO2和Hg具有较高的脱除效率;提出可以采用水洗脱附再生,以重复使用ACF。烟气中各组分之间的相互影响与作用以及副产品资源化利用将是今后研究的重点。The superior structural properties of activated carbon fibers (ACFs) and the influences of catalytic modification treatment upon the gas -absorbing performance have been expounded. After modification, the presence of oxygen - and nitrogen - containing functional groups on the surface of ACFs are advantageous for the removal of multi-pollutants, such as SO2/ NO / Hg, under low temperature. Particularly for removal of SO2 and Hg, it has comparatively high efficiency. It has been pointed out that the ACFs can he regenerated with water washing for desorption. so as to repeatedly use the ACFs. The future work will be focused on interaction among multi components in the flue gas, and the reclaimation of by-products from this process.
