摘　　要：燃煤电厂NOx的排放对我国环境污染相当严重,如何减少NOx的排放量已经成为环境保护所面临的重大挑战之一。选择性催化还原法(SCR)脱硝是目前最为高效的控制烟气氮氧化物排放的有效措施之一。活性碳纤维(ACF)比表面积大、微孔较多且孔径分布均匀、吸附能力强、易于加工,在催化脱硝领域应用广泛。但现在对ACF的研究还不够完善。表述了ACF催化脱硝技术的机理、国内外研究进展和应用情况,同时展望了该项技术的未来发展方向和研究重点应该在低温催化剂的研究开发上。NOx emissions from coal-fired power plant serious harm to the environment in our country, how to reduce NOx emissions has become one of the major challenges. Selective catalytic reduction （SCR） denitrification technology is one of the most effective measures of flue gas NOx emissions control. Activated carbon fiber （ACF） has been applied widely in the denitrification, because it has large specific surface area, a great lot microporosity, strong adsorbing ability and easy machining. But now the research on ACF is still not perfect. The mechanism of ACF catalytic denitrification technology, research progress and application at home and abroad is presented, and prospects the future development and research emphasis on low temperature catalyst.
