Abstract
Electron microprobe analyses are used for characterizing the repartiti on of vanadium deposited during the hydrodemetallation of vanadyl octa ethyl porphyrin on a classical Ni-MoS2-gamma-Al2O3 catalyst. It is fou nd that a part of vanadium can displace Ni initially interacting with the MoS2 platelets (Ni MoS phase) and another part is forming a crown as vanadium sulfide around the catalyst particle. The displaced nickel also formed large nickel sulfide crystallites.
