Quinoline hydrodenitrogenation (HDN) has been studied with supported Pd, Ta, and Pd/Ta catalysts. Although reactions with the Ta catalysts exhibit low conversion to hydrocarbons, they are highly selective for the desired aromatic product. Reactions with Pd catalysts exhibit high conversion to hydrocarbons but are not very selective for the aromatic product. Reactions with small amounts of Pd added to the supported Ta catalyst exhibit greater hydrocarbon conversions than that obtained with the Ta catalysts as well as achieve a selectivity for the aromatic product greater than that obtained with the Pd catalysts.
