Soutenance de Thèse : Effet du support sur la morphologie et l’activité des catalyseurs d’hydrodésulfuration

22 November 2017

Abstract: The support effect on the sulfide phases formation, i.e. morphology, sites dispersion, structure and catalytic activity for hydrotreating catalysts was studied. The study started by Mo catalysts and followed by CoMo catalysts supported on alumina silica and titania. The support effect appeared to be the key factor to control the morphology of MoS2 slabs. The morphology was studied using a powerful technique so-called IR/CO, i.e. CO adsorption followed by FTIR spectroscopy. This method allows the distinction of two types of edge exposed on the MoS2 slabs so-called M- and S-edge and then permits the study of the morphology by the S-/M-edge ratio. The distinction of M- and S-edge sites allowed studying CoMoS sites structure and their  intrinsic activity.
