Theories of hydrodesulfurization have assumed that W and Mo are catalysts for the reaction and that Co and Ni are promoters which enhance or preserve the activity of the catalysts. To test this, samples of sulfided C-supported Co-, Ni-, W-, and Mo-containing samples were tested as catalysts for thiophene hydrodesulfurization. The results do not clearly define the role of Co and Ni; however, at low concentrations, the promoter function is probably an adequate explanation, but at higher concentrations, more study is indicated to clearly define the role of Co and Ni. Catalytic effects of other C-supported sulfided metals are now being studied. (BLM)
