Ni/Mo2 N as a Highly Active Hydrodenitrogenation Catalyst
摘要:
The catalysts were prepared by the temperature programmed reaction (TPR) of MoO3 with NH3 at various temperatures in the range of 573K~973K, and their hydrodenitrogenation (HDN) activities were tested in situ. It is shown that molybdenum nitride (Mo2N) was formed above 923K and its intermediate MoO2 formed at about 573~623K under the rapid (5K/min. ) TPR conditions. Mo2N is the most active species for pyridine HDN among MoO3, MoO2, MoS2, and Mo2N. Moreover, it can be promoted by adding Ni component. It is shown that the Ni/Mo2N catalyst prepared by adding some NiO into the precursor MoO3 has a steady HDN activity which is far higher than that of the commercial sulfided NiMo/Al2O3 (HR346) catalyst.
