摘　　要：水泥工业是NOX的高排放行业,现有的燃烧控制技术难以满足日益提高的环保要求,因此烟气脱硝技术在水泥工业的应用将势在必行。选择性催化还原(SCR)脱硝技术是脱硝率最高的烟气脱硝技术,在燃煤电厂已有较大规模的应用,但是在水泥工业中的研究和应用相对滞后。简要介绍了SCR脱硝技术工作原理及其在水泥窑炉的应用现状,总结了催化材料研究和应用进展,探讨了水泥窑炉NOX减排用SCR脱硝技术和催化材料的研究方向。Cement production is one of the highest NOx emission industries, where the post-combustion control technology should be utilized in future because the combustion control technology used is difficult to meet the en- hanced demand of environmental protection and emission standard. Selective catalytic reduction technique is the most efficient denitration technology and has been widely used in the field of power plants. However, its utilization in ce- ment industry is relatively few because the commercial SCR technique is not applicable to the condition and component of the exhausted gas from cement kilns. This paper briefly introduced the mechanism of selective catalytic reduction process, reaction mechanism, concluded the application of SCR in cement kilns and discussed the research focus on catalysts for denitration of cement kilns.
