摘要：

A synergy in the hydrogenation of cyclohexene and hydrodesulfurization of thiophene is observed when the so-called “NiMoS” phase, prepared by the HSP method, is mixed with Co9S8. Compared to the properly weighted addition of the components, activities are increased by a factor ofapproximately 2 (for about 25 wt% of Co9S8 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 spill-over hydrogen on catalytic centers associated with “NiMoS” (remote control mechanism). © 1993 Academic Press, Inc.
