Hydrotreating activity of bulk NiB alloy in model reaction of hydrodesulfurization 4,6-dimethyldibenzothiophene

- Stability of NiB alloy in hydrodesulphurisation after 5 days runs.
- Sulphur resistance of NiB alloy during HDS: only partially sulfidation.
- Presence of Ni0 on surface of NiB catalyst after HDS reactions.
- HDS of 4,6-DMDBT a 1st order (alone HDS), 0 order for HDS/HDN - the same active sites.
