Provided is an alumina-based sulfur recovery catalyst as well as its preparation method, characterized in that the catalyst has a specific surface area of at least about 350 m2/g, a pore volume of at least about 0.40 ml/g, and the pore volume of pores having a pore diameter of at least 75 nm comprises at least about 30% of the pore volume. The alumina-based catalyst according to present invention is made from flashed calcined alumina, pseudoboehmite and optionally, a binder. The present invention further relates to an use of the alumina-based sulfur recovery catalyst and a method for recovering sulfur by using this catalyst. |
