Preparation of Ni2P/Al-SBA-15 catalyst and its performance for benzofuran hydrodeoxygenation

The Al-doped Ni 2 P/Al-SBA-15 catalyst with high hydrodeoxygenation (HDO) activity was synthesized by temperature programmed reduction at a relatively low reduction temperature of 400   °C. The as-prepared catalyst was characterized by X-ray diffraction (XRD), H 2 temperature-programmed reduction (H 2 -TPR), X-ray photoelectron spectroscopy (XPS), transmission electron microscope (TEM), NH 3 temperature programmed desorption (NH 3 -TPD), N 2 adsorption–desorption and CO uptake. The effect of Al on benzofuran (BF) HDO performance was investigated. The result indicates that the incorporation of Al into the SBA-15 support can promote the formation of much uniform, smaller, highly dispersed Ni 2 P particles on the catalyst. The Al also contributes to suppress the enrichment of P and promote more exposed Ni sites on the surface. In addition, the incorporation of Al can enhance the acid strength. The total deoxygenated product yield over Ni 2 P/Al-SBA-15 reached 90.3%, which is an increase of 19.4%, when compared with that found for Ni 2 P/SBA-15 (70.9%).
