Many explanations have been suggested for the observed catalytic synergy in Co-Mo hydrodesulfurization catalysts. Many theories assume no appreciable HDS activity for the promoter sulfide phase itself. But some years ago the authors questioned the correctness of this presupposition on the basis of high thiophene-hydrodesulfurization activities measured for carbon-supported Co and Ni sulfide catalysts. They concluded that the possibility of Co or Ni sulfide acting as catalysts instead of promoters for the MoS{sub 2} phase deserves more attention. Therefore, the present study attempted to further elucidate the preparation, structure and HDS activity of carbon-supported Co catalysts.
