Thiophene hydrodesulfurization over transition metal foils: Comparison with metal sulfides

Abstract

The hydrodesulfurization (HDS) of thiophene has been investigated over polycrystalline metal foils of cobalt, molybdenum and rhenium. The measured activities for the Mo and Re foils are similar to those previously determined for low miller index single crystals of Mo and Re. In agreement with published results of HDS studies over unsupported and supported metal sulfides, the HDS activities of the three metal foils were found to increase in the order Co < Mo < Re. These results suggest that it is most probably correct to think of cobalt as a promoter of molybdenum in Co-Mo catalysts, and that metal surfaces are suitable substrates for model studies of HDS.
