Transition-metal molybdenum phosphides were prepared by direct reduction of an amorphous phosphate precursor in hydrogen at relatively low temperature (650°C). XRD measurements showed that pure molybdenum phosphide was formed after the reduction of H2. The reactivity was determined in a continuous-flow microreactor at H2 pressure of 3 MPa. A sample of prepared molybdenum phosphide catalyst diluted with γ-Al2O3 (20% phosphate precursor) was used for simultaneous HDN, HDS, and hydrogenation of aromatics. Effect of space velocity, flow rate of hydrogen, and reaction time and temperature on hydrotreating performance were studied. Pyridine, thiophene, and cyclohexene were used as model compounds, their contents were 5,5, and 20%, respectively. Cyclohexane was used as solvent.
