磷钼酸改性Ni催化剂上秸秆液化油的加氢脱氧研究
Hydrogenation deoxidization of straw liquefied oil over phosphomolybdic acid modified Ni catalyst
摘要
Abstract
Ni/γ-Al2O3 and phosphomolybdic acid promoted Ni/γ-Al2O3-HMoP catalysts were prepared by impregnation, and characterized by BET, XRD, H2-TPR and NH3-TPD. The effect of phosphomolybdic acid on catalytic performance of the catalysts in hydrogenation of straw liquefied oil was investigated. The results showed that phosphomolybdic acid modification can effectively improve the catalytic activity in the hydrodeoxygenation of straw liquefied oil. Phosphomolybdic acid modification, on the one hand, can increase the dispersion of the active metal on the surface of catalyst support, and make the sizes of the active Ni particles in the micropores of support tend to be uniform, which promotes the dispersion of active Ni species, and increases selectivity and stability of the catalyst. On the other hand, the interaction between phosphomolybdic acid and nickel salt improves the activity and reducibility of nickel. Over the catalyst 10%Ni/γ-Al2O3-HMoP-3, the most complete hydrogenation of straw liquefied oil can be obtained at the conditions of 250℃and 4.5MPa, and the color of the refined oil becomes shallow obviously.关键词
