What should be noted when selecting SCR catalyst models?
Publishdate：2018-07-26 Views：13
An important part of the SCR system is to choose the correct type of SCR catalyst when using it, so as to ensure the normal operation of the SCR system. Moreover, only by selecting catalysts with very suitable pore size and intercept can blockages caused by ash accumulation be avoided. So what should be noted when selecting SCR catalysts?
1. Pay attention to the height of the catalyst
Although the cross-sections of SCR catalysts produced in various places are the same now, their module heights are different. Therefore, when selecting catalyst models for in situ SCR systems, the module height should be considered based on the parameters designed for different projects and actual performance requirements. It is necessary to meet the system's layer height dimensions and large load-bearing requirements, so that different catalysts can be interchanged in applications.
2. Pay attention to the factors of catalyst failure
Due to the decline in resistance of advanced SCR catalysts, their performance will deteriorate with prolonged use. So, in order to choose the appropriate SCR catalyst model for the SCR system, the degradation factor of the catalyst needs to be considered. The appropriate temperature range, alkali metal composition, halogen composition, etc. should be selected according to the actual situation of the project, so as to effectively control the degradation of the catalyst.
3. Pay attention to the pore structure of the catalyst
To choose a suitable SCR catalyst model, attention should also be paid to how the pore structure of the catalyst is designed. The good effect is to reduce diffusion resistance, as this can strengthen the catalyst's resistance to arsenides and control the speed of reader aggregation.
The above points are the precautions to be taken when selecting the SCR catalyst model. As SCR catalyst is a very important component of the SCR system, the selection should not be careless. Therefore, it is not only necessary to purchase from a leading SCR catalyst manufacturer in the industry, but also to choose the correct model based on the actual parameters and performance requirements of the project.
