Preparation and Ultra-Deep Hydrorefining Performance of Ni-P/Al₂O₃-ZrO₂ Catalysts

Abstract:

A series of Al₂O₃-ZrO₂ (AZ-X) composite oxides with different ZrO₂ contents were prepared by a chemical precipitation method. Ni-P/AZ-X catalysts were prepared by temperature-programmed reduction. The supports and catalysts were extensively characterized by X-ray diffraction (XRD) and BET. The effects of support composition and P/Ni molar ratios on the catalytic performance of the catalysts were investigated by thiophene hydrodesulfurization (HDS) and pyridine hydrodenitrogenation (HDN). In comparison with Al₂O₃, Al₂O₃-ZrO₂ (20 wt% ZrO₂) composite oxide supported Ni-P catalyst exhibited higher activity and the activities of HDS and HDN increased by 7.5 % and 11.1 %, respectively. Studies of Ni-P/AZ-X catalysts with varying initial P/Ni molar ratios indicated that oxidic precursors with molar ratios of P/Ni = 2/1 yielded catalyst containing phase-pure Ni₂P which exhibited optimal activity.
