On the structure and hydrotreating performance of carbon-supported CoMo- and NiMo-sulfides

- Sulfidation & hydrotreating performance of C-supported CoMo catalysts investigated.
- High-pressure sulfidation: type I to II transition of the active 'Co-Mo-S' phase.
- Gas- and liquid-phase HDS and HDN model reactions: NiMo/C > NiMo/Al2O3.
- Cat-cracked Heavy Gas-Oil: NiMo/C < NiMo/Al2O3 due to adsorption poly-aromatics.
