Abstract

Electron microprobe analyses are used for characterizing the repartition of vanadium deposited during the hydrodemetallation of vanadyl octaethyl porphyrin on a classical Ni−MoS2-γ-Al2O3 catalyst. It is found 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.
