1. A method for the desulfurization of a sulfur-containing hydrocarbon feedstock, the method comprising introducing the sulfur-containing feedstock within a reactor in the presence of a gas atmosphere and a catalyst structure, wherein the catalyst structure comprises a porous support structure that comprises an aluminosilicate material including at least the following metals located in the aluminosilicate material:

silver and gallium, or

gallium and cerium, or

silver, gallium and cerium, or

silver, gallium and molybdenum;

wherein the gas atmosphere consists of pure gas or a mixture of gases selected from the group consisting of nitrogen, helium, methane, and natural gas.
