A process is disclosed for the hydrodesulfurization of sulfur-containing hydrocarbon fuel with reduced ternary molybdenum sulfides, known as Chevrel phase compounds. Chevrel phase compounds of the general composition M x Mo 6 S 8, with M being Ho, Pb, Sn, Ag, In, Cu, Fe, Ni, or Co, were found to hav
A process is disclosed for the hydrodesulfurization of sulfur-containing hydrocarbon fuel with reduced ternary molybdenum sulfides, known as Chevrel phase compounds. Chevrel phase compounds of the general composition M x Mo 6 S 8, with M being Ho, Pb, Sn, Ag, In, Cu, Fe, Ni, or Co, were found to have hydrodesulfurization activities comparable to model unpromoted and cobalt-promoted MoS 2 catalysts. The most active catalysts were the "large" cation compounds (Ho, Pb, Sn), and the least active catalysts were the "small" cation compounds (Cu, Fe, Ni, Co.).

1. A hydrodesulfurization process comprising, contacting a sulfur-containing gaseous hydrocarbon with a chevrel phase compound of the general formula: M x Mo 6 S 8 at a concentration and for a time sufficient to selectively reduce the sulfur content of the hydrocarbon, wherein M is selected from large and intermediate cations for chevrel phase compounds and M and x are selected to maintain the oxidation state of most of the Mo to less than +4. 2. The hydrodesulfurization process of claim 1, wherein the reaction is conducted at an elevated temperature. 3. The hydrodesulfurization process of claim 2, wherein the temperature is about 400° C. 4. The hydrodesulfurization process of claim 1, wherein the sulfur containing compounds include thiophene, Mercaptans disulfides and condensed thiophenes. 5. The hydrodesulfurization process of claim 1, wherein M is selected from the group consisting of Ho, Pb, Sn, Ag and In. 6. The hydrodesulfurization process of claim 1, wherein M is selected from the group consisting of Ho, Pb and Sn. 7. The hydrodesulfurization process of claim 1, wherein the oxidation state of Mo in the chevrel phase compound is maintained in the range of from +2 to +22/3. 8. A hydrodesulfurization process comprising, contacting a sulfur-containing gaseous hydrocarbon in the presence of hydrogen with a Chevrel phase compound of the general formula: M x Mo 6 Z 8 at an elevated temperature for a time sufficient to reduce the sulfur content of the hydrocarbon while maintaining hydrogenation reactions at a relatively low level, wherein M is selected from large and intermediate cations for chevrel phase compounds and Z is selected from the group consisting of sulfur, selenium and tellurium. 9. The hydrodesulfurization process of claim 8, wherein the oxidation state of Mo in the chevrel phase compounds is less than +3. 10. The hydrodesulfurization process of claim 9, wherein the sulfur-containing gaseous hydrocarbon is contacted with the chevrel phase compounds intermittently. 11. The hydrodesulfurization process of claim 8, wherein the desulfurization takes place in the absence of oxygen. 12. The hydrodesulfurization process of claim 8, wherein the desulfurization takes place at atmospheric pressure at a temperature of about 400° C. 13. The hydrodesulfurization process of claim 8, wherein M is selected from the group consisting of Ho, Pb, Sn, Ag and In. 14. The hydrodesulfurization process of claim 8, wherein M is selected from the group consisting of Ho, Pb and Sn. 15. The hydrodesulfurization process of claim 14, wherein Z is sulfur. 16. The hydrodesulfurization process of claim 8, wherein the oxidation state of Mo in the chevrel phase compounds is less than +3. 17. The hydrodesulfurization process of claim 8, wherein the sulfur-containing gaseous hydrocarbon is contacted with the chevrel phase compounds intermittently.
