Preparation of Mo/Al2O3 Sulfide Catalysts Modified by Ir Nanoparticles.
Original language description
Preparation and catalytic properties of Ir/alumina and Ir-Mo/alumina sulfide catalyst were studied in hydrodenitrogenation (HDN) of pyridine and hydrodesulfurization (HDS) of thiophene. The Ir added to a Mo/alumina catalyst is amount 0.1-0.8 wt % increased activities in both reactions by a factor of about 2-3. The main factors, leading to improvement of activity of modified Ir-Mo catalysts, were Ir dispersion, and amount and of the Mo phase before Ir deposition, i.e. whether oxidic or sulfided and the way of catalyst activation. The effects of starting Ir compounds and deposition order of Ir and Mo seem to be of a smaller importance.
