Abstract
AbstractModel hydrodesulfurization (HDS) catalysts having a general stoichiometry of Co2xMo1‐xS2 (x = 0.025‐0.3) are synthesized using a solid‐state procedure based on reaction of elemental sulfur with metallic cobalt and molybdenum powders at 783 K. Results of XRD, selected area electron diffraction, and activity tests in a flow reactor show that high HDS activity coincides with the presence of a nonstoichiometric bulk phase, which is very similar to nonstoichiometric molybdenum sulfide.
