The application discloses a high-sulfur capacity hierarchical porous structure desulfurizer and a preparation method thereof, and belongs to the technical field of gas purification materials. The hierarchical porous alumina carrier is obtained by an in-situ hydrothermal growth method, and then the active components and catalytic additives, such as Zn, Cu, Ce, Mg, La and metal oxides, are highly dispersedly loaded in the hierarchical pores by using a complex co-precipitation method, and the desulfurizer is obtained after being dried and formed by calcination. The application has the advantages that the hierarchical porous structure greatly promotes the reaction mass transfer and provides abundant active site loading space; and the synergistic effect of the multiple additives effectively improves the sulfuration reaction activity and the anti-sintering capacity. The desulfurizer prepared by the method has excellent performances such as high sulfur capacity, fast reaction speed, high mechanical strength and good stability, and is particularly suitable for high-precision deep removal of hydrogen sulfide in gas such as synthetic gas and natural gas.
