不同方法制备的介孔Ni/MgO催化剂上水蒸气重整苯酚制氢
Steam reforming of phenol for producing hydrogen over nickel support on MgO prepared by different methods
摘要
Abstract
MgO-supported nickel catalysts were prepared by impregnation and hydrothermal coprecipitation methods;they were characterized by XRD, N2 sorption, H2-TPR, TEM and TG and used in the steam reforming of biomass oil model compound-phenol for hydrogen production. The results indicated that the NiO/MgO solid solution prepared by the impregnation method displays higher surface area (60. 6 m2/g) and larger pore diameter (10. 1 nm), in comparison with that prepared by hydrothermal coprecipitation. After reduction, the mesoporous Ni/MgO catalyst obtained from impregnation exhibits small and uniform Ni nanoparticles ( 5 . 0-6 . 0 nm ) with high dispersion ( 19 . 44%) . As high surface area is favorable for the dispersion of Ni nanoparticles and mesoporous structure can promote the mass transfer of reactants and products, the Ni/MgO catalyst exhibits high activity as well as excellent coke resistance ability and long-term stability in the steam reforming of phenol.关键词
