However, the catalyst is easily contaminated by harmful substances such as potassium and lead during the working process, which leads to the failure of the catalyst. Therefore, this paper will study the preparation, characterization, catalytic performance of titanium-based SCR catalysts and the mechanism of potassium and lead poisoning, as well as exploring effective methods to relieve poisoning.Firstly, this paper will introduce the preparation method, characterization method and catalytic performance testing method of titanium-based SCR catalysts, and characterize and test the obtained catalysts. Then, this paper will provide the source and poisoning mechanism of harmful substances such as potassium and lead in the catalyst, and analyze in detail the 精品文档---下载后可任意编辑impact of harmful substances on the activity and stability of the catalyst.Finally, this paper will explore effective methods to relieve poisoning, including getting rid of harmful substances, adding antidotes, and changing the structure of the catalyst. Through experimental verification and data analysis, this paper will obtain the poisoning mechanism and methods to relieve poisoning of catalysts, providing reference for the application of titanium-based SCR catalysts.Keywords: Titanium-based SCR catalyst; Poisoning mechanism; Methods to relieve poisoning; Characterization; Catalytic performance
