Samenvatting

The influence of physisorbed water on the formation of nickel- sulfide species in a Co-57 doped ion exchange type Co-57:NiNaY catalyst is studied by Mossbauer Emission Spectroscopy. The absence or presence of physisorbed water during sulfidation seems to have no influence on the local nickel environment of the formed Ni-sulfide species. This result is confirmed by EXAFS measurements. In spite of the resemblance found in MES and EXAFS a large difference is found for the initial HDS activities, which is explained by the different particle sizes (HREM) found at the outer surface of the zeolite
