Hydrodenitrogenation of Quinoline Over a Dispersed Molybdenium Catalyst Using in situ Hydrogen

Abstract

Hydrodenitrogenation (HDN) of quinoline using a Mo-based dispersed catalyst was studied in a batch reactor using H 2 generated in situ via the water gas shift reaction. In situ H 2 was found to be more active for HDN than externally supplied H 2 . Both water and H 2 S have an effect on HDN.

Hydrodenitrogenation of quinoline and its intermediates over sulfided NiW/γ‐Al2O3 in the absence and presence of H2S

“…1, the selectivities of THQ1 and THQ5 extrapolated nonzero values at space time zero, suggesting that they were primary products. The selectivity of THQ1 is about 9 times that of THQ5 at τ = 0.56, indicating that hydrogenation of quinoline to THQ1 proceeds much easier than its hydrogenation to THQ5, since the heterocyclic ring is more easily hydrogenated than the benzenoid ring [12] . The selectivity of THQ1 decreased dramatically with increasing space time, indicating that it converted further into OPA and DHQ which were reaction intermediates.…”
