A synergy in the hydrogenation of cyclohexene and hydrodesulfurization of thiophene is observed when the so-called [open quotes]NiMoS[close quotes] phase, prepared by the HSP method, is mixed with Co[sub 9]S[sub 8]. Compared to the properly weighted addition of the components, activities are increased by a factor of approximately 2 (for about 25 wt % of Co[sub 9]S[sub 8] in the mixture) and 3.5 (for about 75 wt %), in hydrogenation and hydrodesulfurization, respectively. The results can be interpreted as due to the action of spillover hydrogen on catalytic centers associated with [open quotes]NiMoS[close quotes] (remote control mechanism). 20 refs., 2 figs.
