Abstract: To reduce the operation cost of SCR denitration system and ensure the system operation in good condition, this paper constructs the whole process management model for the SCR denitration catalysts. The management model covers the entire process of catalyst production, operation and deactivation, which includes factory surveillance, factory acceptance test, performance testing, life assessment, regeneration technique and so on. By means of catalytic performance testing, the real time performance of the catalyst from production to operation can be mastered and the assessment and treatment can be conducted timely whenever abnormalities are observed. Thus by adopting the whole process management model, the catalyst life can be further extended, and the catalytic potential can be fully taken advantage of.
