摘　　要：电厂烟气SCR脱硝技术存在着投资、运行成本高,难以对旧电厂进行改造等缺点。低温SCR法可以部分克服这些难题,但是现有的低温SCR催化剂脱硝效率差,易受SO2和水蒸气的中毒影响。针对低温SCR的催化剂开发情况和应用实例进行了综述,对该技术下一步的研究进行了展望。The high investment and operating-cost, not easy to retrofit in old power plant properly were the main disadvantages of the generally used SCR method. Low-temperature SCR technology could overcome those problems partly, but the catalysts easy to be poisoned by SO2 and H2O in present. The research and utility of the low temperature SCR catalysts were summarized and further development of SCR technology was proposed in the end.
