| Abstract: | A series of MoNiP/Al 2O 3 catalysts were prepared by keeping the active components (Mo, Ni and P) constant and varying the preparation conditions (calcination procedure and temperature). PASCA (positron annihilation spectroscopy for chemical analysis), XPS (X ray photoelectron spectroscopy), STEM (scanning transmission electron microscopy) and microreactor were applied to characterize the dispersion states of the active components on the surface of the catalysts. The results indicate that the HDN activity of the catalysts is associated with the dispersion degrees of both Mo and Ni. Besides, higher HDN activity is also related to the dispersion of Mo and Ni with a fixed Mo/Ni molar ratio. |
