摘　　要：本文通过对灰分及失活催化剂的取样分析,探究了水泥项目SCR脱硝催化剂的失活原因,同时采用不同方法对失活催化剂进行再生,研究如何达到最佳再生效果。经成分分析表明,水泥项目SCR脱硝催化剂失活的原因主要是含钙灰分的覆盖、碱金属中毒以及可能的铊中毒。失活的催化剂经过独有技术的全面再生处理能够去除各类中毒物质,并清除微孔堵塞。In this paper,the deactivation reason of SCR denitration catalyst in cement plant was studied by sampling and analyzing the ash content and deactivation catalyst.The deactivated catalyst was regenerated by different methods to research how to achieve the best regeneration effect.The composition analysis showed that the deactivation of SCR catalyst in cement industry was mainly caused by the covering of calcium ash,alkali metal poisoning and possibly thallium poisoning.The deactivated catalyst was fully regenerated with a unique technology which can remove various toxic substances and eliminate micropore blockages.
