The present application discloses a modified denitration catalyst. The denitration catalyst is used as a carrier, and at least one of iron, cerium and sulfate is used as a modified component to improve the components and surface properties of the denitration catalyst. Under the premise that the macroscopic shape of the catalyst remains unchanged, the impregnation method is used to improve the composition and surface properties of the catalyst, and the preparation process is mild, non-toxic and harmless. The improved catalyst improves the denitration activity of the catalyst, broadens the reaction temperature window, and has higher N 2 selectivity, and makes the modified commercial denitration catalyst have stronger resistance to alkali metal, alkaline earth metal and heavy metal poisoning ability, effectively improving the service life of the catalyst. |
