摘要：
Catalysts with eggshell/uniform Mo concentration profiles were prepared by a reaction of ZrO2 and ZrO(OH)2 extrudates with an aqueous slurry of MoO3. The thickness of the shell was regulated by the amount of MoO3. CoCO3 was adsorbed onto MoO3/ZrO2 from its aqueous slurry. The ZrO2-supported catalysts were compared to their TiO2-supported and industrial reference Al2O3-supported counterparts in a model reaction of benzothiophene hydrodesulfurization.
