Abstract

Cobalt-, nickel-, and zinc-promoted as well as nonpromoted catalysts based on MoO3, MoS2, and WS2 supported on ¿-Al2O3 and SiO2 have been prepared in three essentially different ways. Their thiophene hydrodesulfurization activities have been determined under continuous flow conditions at atmospheric pressure and 400 °C. Experimental evidence is reported for the relevance of both the monolayer and intercalation model to the preparation and operation of active catalysts. In actual operation the best description of the catalyst is given by the intercalation model.
