| description | The invention relates to a complex iron desulfurization catalyst and a preparation method thereof, and belongs to the field of gas purification. The desulfurization catalyst comprises the raw materials in parts by weight: 2.5-9 parts of a complexing agent, 1.5-6 parts of an iron source, 0.01-1.5 parts of a modifier, 0.01-1.5 parts of a stabilizer and a pH regulator, wherein the iron source is selected from an iron-based bimetallic compound doped with a dissimilar metal element M, and M represents one or more of dissimilar metal elements Cu, Co and Ni. Harmful anion impurities do not need to beintroduced in the preparation process of the complex iron desulfurization catalyst, the problems of desulfurization equipment corrosion, high desulfurization wastewater treatment difficulty and the like are avoided, and the catalytic activity and desulfurization efficiency are improved through the synergistic effect between Fe and dissimilar metal M in the desulfurization catalyst; in the use process of the desulfurizati |
