(57) [Summary] [Problem] At least mercaptans such as TBM and DM Sulfur compounds in the fuel gas containing both sulfides such as S are adsorbed and removed simultaneously and more efficiently with one desulfurizer. SOLUTION: A desulfurization vessel is filled with adsorbents having different sulfur compound adsorption capacities on the upstream side and downstream side, or two or more adsorbents having different sulfur compound adsorption capacities are mixed and filled. A fuel gas desulfurization apparatus, and a fuel gas desulfurization method using the same. As one kind of adsorbents having different sulfur compound adsorption capacities, it is preferable that “X-type, Y-type, β-type zeolite be added to Ag, Cu, Zn, Fe, C”. An adsorbent formed by supporting one or more transition metals selected from o and Ni by ion exchange is used. |
