Simultaneous hydrodenitrogenation of pyridine and hydrodesulfurization of thiophene over carbon-supported platinum metal sulfides

The activity and selectivity in parallel hydrodenitrogenation and hydrodesulfurization of carbon-supported sulfides of Ru, Rh, Pd, Ir, and Pt were evaluated using the simultaneous reaction of pyridine and thiophene at 280 °C and under 2 MPa. The properties of these sulfldes were also compared with t...

Description
Summary:The activity and selectivity in parallel hydrodenitrogenation and hydrodesulfurization of carbon-supported sulfides of Ru, Rh, Pd, Ir, and Pt were evaluated using the simultaneous reaction of pyridine and thiophene at 280 °C and under 2 MPa. The properties of these sulfldes were also compared with the behavior of commercial NiMo/alumina and CoMo/alumina Shell catalysts. The carbon-supported sulfides of platinum metals were better hydrodesulfurization catalysts and much better hydrodenitrogenation catalysts than the commercial bimetallic systems. The HDN HDS selectivity of the Rh, Ru, and Pd catalysts was similar to the selectivity of CoMo and NiMo systems but the Ir and Pt catalysts were extremely selective for hydrodenitrogenation. The results suggest that the use of active carbon as the support contributed to the exceptional hydrodenitrogenation properties of the sulfides of platinum metals.
