Des Co-Mo catalyseurs à hydrodésulfuration ont été étudiés par application de spectroscopie Mössbauer. En état calciné les Co ions se trouvent localisés dans le support en alumine. Pendant l'activation, une structure de surface se forme contenant Co, Mo, et S. Les résultats de mesures indiquent que le procédé catalytique est associé avec un changement en valence des Co ions.Co-Mo hydrodesulfurization catalysts have been studied by the use of Mössbauer spectroscopy. In the calcined state the Co ions are found to be located in the alumina carrier. During activation a surface structure containing Co, Mo, and S is formed. The measurements indicate that the catalytic process is associated with a valence change of the Co ions
