摘      要：Transition metal molybdenum phosphides were prepared by direct reduction of an amorphous phosphate precursor in hydrogen at relatively low temperature (650 ℃). XRD (X ray diffraction analysis) measurements showed that pure molybdenum phosphide formed after the reduction with H 2. The reactivity was determined in a continuous flow microreactor at a H 2 pressure of 3.0 MPa. A sample of prepared molybdenum phosphide catalyst diluted with γ Al 2O 3 (20% phosphate precursor) was used for simultaneous HDN (Hydrodenitrogenation), HDS (Hydrodesulfurization) and HDY(Hydrogenation of aromatics). The influences of space velocity, flow rate of hydrogen, reaction time and temperature on hydrotreating performance were studied. Pyridine, thiophene and cyclohexene were used as model compounds, their contents were respectively 5%, 5% and 20%. Cyclohexane was used as the solvent.
