摘要/Abstract

摘要： 对催化剂的实际运行性能进行掌控，是保证SCR脱硝系统稳定运行的关键。以某电厂新鲜催化剂及运行不同时间的催化剂为研究对象，对催化剂理化特性、机械特性、微观结构进行测试，分析其对运行效果的影响，并对运行中催化剂的工艺特性和活性进行分析，以期通过运行中催化剂性能检测为脱硝催化剂的更换及加装提供依据。研究结果表明，某燃煤电厂催化剂运行2年后，逃逸氨指标已接近保证值的上限，存在一定的运行风险。为保证脱硝机组的安全高效稳定运行，应积极开展催化剂运行后的管理工作。

Abstract: The control of the actual operating performance of the catalyst is critical to the stable operation of SCR denitrification system. In this paper, the fresh catalyst and used catalyst after different time periods of operation in a power plant were taken as the research objects. The physical and chemical properties, mechanical properties, and microstructure of catalyst are tested, and its impact on the operation of the catalyst is analyzed. Through the study on the process characteristics and activity of the catalyst in operation, it is expected that the catalyst performance test will provide the basis for the replacement and installation of the denitration catalyst. The results show that after the catalyst having been installed and used for more than two years in the coal-fired power plant, operational risk has increased to certain level with the escaping rate of ammonia approaching the upper limit of the guaranteed value . In order to ensure the safe and efficient operation of the denitrification system, the catalyst management should be actively involved after being put into service.

Key words: coal-fired power plant, denitrification, SCR, catalyst, catalyst activity, denitrification efficiency, escaping ammonia
