Hydrodenitrogenation of Aleksinac shale oil distillates in a pilot trickle-bed reactor

Hydrodenitrogenation (HDN) of the Aleksinac shale oil distillates was studied in a pilot trickle-bed reactor at 340–435°C, 8.0 MPa, 1–4.57 h−1 liquid hourly space velocity (LHSV) and 500 cm3 (STP) of H2/cm3 oil. The commercial CoMoAl2O3 and NiMoAl2O3 presulfided catalysts were evaluated for the HDN of three different shale oil distillates. The initial HDN catalyst deactivation was followed using a linear catalyst deactivation model. The …
