Abstract
IR characterization and activity measurements of a sulfided Co-Mo/Al2O3 catalyst (3.6% CoO; 14% MoO3) prepared by thermodecomposition of Co(CO)3NO on a sulfided Mo/Al2O3 sample are compared to those of the conventional Co-Mo/Al2O3 industrial catalyst. The ex-carbonyl preparation leads to a higher degree of promotion for the Co-Mo couple, as evidenced by a two-fold increase in HDS activity and by a more intense signal of adsorbed CO on the promoted sites. On the other hand, the hydrogénation activity is not sensitive to the method of preparation.
