Abstract
The influence of physisorbed water on the sulfidation of an ion exchan ged CoNaY catalyst is studied by Mossbauer Emission Spectroscopy, Exte nded X-ray Absorption Fine Structure and Hydrodesulfurization activity measurements. Physisorbed water present during sulfidation affects th e Co-sulfide dispersion and the initial HDS activity. Its removal prio r to sulfidation clearly results in an improvement of these two cataly st parameters.
