摘 要: 氨选择性催化还原(SCR)技术广泛应用于固定源氮氧化物污染控制,该技术的核心是催化剂。目前,研制具有低温活性的催化剂是国内外该领域的热点。文章综述了活性炭、活性炭纤维、碳成型物为载体的催化剂,以氨为还原剂,低温选择性催化还原锅炉烟气氮氧化物(NOx)的研究现状,并对该技术的发展做了展望,特别提出了碳的另一同素异性体碳纳米管在低温选择催化还原NOx上的应用前景。 Selective catalytic reduction (SCR) of NO. with NH3 is widely used in stationary source pollution control,and the key of SCR process is the catalyst. At present the development of catalysts with good activity at low temperatures becomes the hot point in this field. The SCR activity of carbon supported catalysts (active carbon, active carbon fiber and carbon-coated monolith ) at low temperatures is summarized. The progress of SCR research in the future is discussed, and the carbon nanotubes (CNTs) are suggested as promising support materials for the SCR catalysts.
