| 中文摘要: |
| 某规模为5 000 t/d的水泥熟料生产线SCR脱硝装置运行8 000 h后，从反应器内取出脱硝催化剂测试块，对每一层测试块样品的几何尺寸、外观、微观结构、化学成分、微量元素、机械强度和工艺性能等项目进行测试，并将运行样品的各项性能检测结果同新催化剂进行对比，分析了脱硝催化剂运行样品性能指标变化趋势及产生的原因，总结了脱硝催化剂性能衰减规律，对水泥窑用脱硝催化剂的运行与管理提出了建议。 |
| 英文摘要: |
| After the SCR denitration device of a cement clinker production line with a scale of 500000t/d runs for 80000 h， each layer of catalyst test blocks is taken out from the reactor to test the geometric size， appearance， microstructure， chemical composition， trace elements， wear strength and activity of the catalyst， etc. In this project， the performance test results of each layer of catalyst were compared with the new catalyst， the reasons for the change of catalyst performance indicators were analyzed， the law of catalyst performance attenuation was summarized， and management suggestions were put forward for the operation test of cement kiln catalysts. |
