Various transition-metal catalysts supported on γ-alumina were prepared and applied for the hydrodenitrogenation (HDN) of pyridine. The NiMo/Al_2O_3 catalyst showed higher activity than the Mo/Al_2O_3 catalyst. On the basis of the results of reaction experiments and measurements of IR and TPR, the enhancement in the HDN activity with nickel addition could be attributed more to the improvement in the reducibility of molybdenum than to the effect of Bronsted acid site.
