TUNGSTEN AND RHENIUM AS HYDROGENATION AGENTS IN THE HYDRODENITROGENATION OF PYRIDINE USING STACKED BED CATALYST SYSTEMS

This study analyses the hydrodenitrogenation (HDN) of pyridine using a stacked bed catalyst system, composed of a first hydrogenating bed of Re/γ-Al2O3 or W/γ-Al2O3, over a second bed of Ni-Re/γ-Al2O3 (HDN bed). Using potentiometric methods, it can be seen that the Re/&...
