Catalytic hydrodenitrogenation under mild conditions was improved by using modified solid catalyst coupled with[Bmim]BF4 ionic liquid.Ni2P/SBA-15 catalyst was modified with different Mo loadings and structures of Mo-Ni2P/SBA-15 modified catalysts were characterized by N2 adsorption-desorption

X-ray diffraction

and X-ray photoelectron spectroscopy.These catalysts coupled with[Bmim]BF4 were evaluated for denitrification of pyrrolidine model compound in batch reactor at mild pressure and temperature.The results showed that Mo addition improved catalytic hydrodenitrogenation activity.At low temperature

the denitrification process was dominated by ionic liquid extraction.As temperature was increased

coupling hydrodenitrogenation was more obvious.5% Mo-25% Ni2P/SBA-15 catalyst coupled with[Bmim]BF4 exhibited the best hydrodenitrogenation efficiency up to 80.1% at 150℃ and 3 MPa.Furthermore

the ionic liquid did not show significant decrease in hydrogenation efficiency after four cycles.The presence of ionic liquids achieved good catalytic hydrodenitrogenation under mild conditions

which could be a new process for catalytic hydrogenation under low temperature and pressure conditions.
