A sulfur sorbent composition includes a support structure and a double oxide sulfur scavenger that is supported on the support structure. The support structure may be diatomaceous earth or a zeolitic-type mineral, and the sulfur scavenger a metal and/or a metal oxide and/or a combination of two or more metal and/or oxides. The sulfur sorbent composition can be used either as a stand-alone device or in conjunction with a fuel reformer to provide a sulfur-free stream.

1. A sulfur sorbent composition comprising: at least one chemically inert porous support structure; anda sulfur scavenger material supported on the porous support structure and incorporated into the pores of the porous support structure, the sulfur scavenger material consisting of a crystalline solid double oxide material that does not melt during sulfur scavenging, wherein the sulfur scavenger material retains its crystalline structure and phase stability during sulfur scavenging at a temperature ranging from about 450° C. to about 800° C. 2. The sulfur sorbent composition of claim 1, the crystalline solid double oxide material having a formulation of ABOx, wherein x is 3 or 4 and A and B are selected from the group Ti, Mn, Fe, Co, Ni, Cu, Zn, Mo, and W. 3. The sulfur sorbent composition of claim 1, wherein the crystalline solid double oxide material comprises oxides of zinc and molybdenum. 4. The composition of claim 1, wherein the porous support structure comprises diatomaceous earth that contains periodic nanopores. 5. The composition of claim 1, wherein the porous support structure comprises zeolitic-type mineral that contains mesopores. 6. The composition of claim 1, wherein the crystalline solid double oxide material is one of: zinc molybdate (ZnMoO4) or zinc molybdite (ZnMoO3). 7. The composition of claim 1, wherein the porous support structure comprises clinoptilolite, and the crystalline solid double oxide material is one of: zinc molybdate (ZnMoO4) or zinc molybdite (ZnMoO3). 8. The composition of claim 1, wherein the porous support structure comprises diatomite, and the crystalline solid double oxide material is zinc molybdate (ZnMoO4). 9. The composition of claim 1, adapted for use in a reforming process to substantially remove sulfur from a fuel. 10. The composition of claim 1, adapted for use in a reforming process to substantially remove sulfur from a jet fuel. 11. The composition of claim 1, adapted for use in a reforming process to substantially remove sulfur from a diesel fuel. 12. The composition of claim 1, adapted for use in a reforming process to substantially remove sulfur from a reformate. 13. The composition of claim 1, adapted for use in a liquid phase desulfurization process. 14. The composition of claim 1, adapted for use in a vapor phase desulfurization process. 15. The composition of claim 1, adapted for use in a steam reforming process of sulfur-laden fuel. 16. The sulfur sorbent composition of claim 1, wherein the sulfur scavenger material is present from about 1% to about 10%, by weight, of the support structure. 17. A reformer device comprising a sulfur scavenger material supported on a porous support structure and incorporated into the pores of the porous support structure, wherein the sulfur scavenger material consists of a crystalline solid double oxide material that does not melt during sulfur scavenging, wherein sulfur scavenging occurs from about 450° C. to about 800° C. 18.
