چکیده انگلیسی

The Ni2P/MgAlO catalysts with different MgO/Al2O3 ratios were prepared by the phosphidation of corresponding Ni/MgAlO catalysts with triphenylphosphine in liquid phase. It was found that the MgO/Al2O3 ratio affected the Ni2P/MgAlO catalysts significantly. The Ni2P/MgAlO catalyst with the MgO/Al2O3 ratio of 3 (w/w) exhibited the highly dispersed Ni2P particles (∼9 nm) with the highest CO uptake (344 µmol/g) and thus the highest activities for the hydrotreating reactions. However, based on the CO uptakes on the used catalysts, the TOF values for the hydrodesulphurization of dibenzothiophene as well as those for the hydrogenation of tetralin on all the Ni2P/MgAlO catalysts were respectively similar, indicating that the MgO/Al2O3 ratio did not affect the intrinsic activities of Ni2P supported on the MgAlO support for the hydrotreating reactions.

Among the Ni2P/MgAlO catalysts, the one with MgO/Al2O3 weight ratio of 3 exhibited highly dispersed Ni2P particles (∼9 nm) with the highest CO uptake (344 µmol/g) and thus the highest activities for the hydrotreating reactions.Figure optionsDownload as PowerPoint slide
