In this study, spherical γ-Al2O3 supported metal phosphide (CuP, MoP, and FeP) catalysts were successfully prepared by combining sol-gel and spray pyrolysis methods. First boehmite sol was prepared by a Yoldas-process and then the corresponding metal salts and phosphorus precursor were added to the sol at the desired concentration, followed by spray pyrolysis of the mixed solution. As the well-mixed solution was transformed to spherical γ-Al2O3 supported metal phosphide catalysts druring spray pyrolysis process, the metal phoshide species were uniformly distributed on the mesoporous γ-Al2O3 supports. The product catalysts were investigated under different conditions for hydrodeoxygenation of bio-oil model compound, 2-furyl methyl ketone (FMK), which is the main component of the bio-oil product from pyrolysis of Saccharina japonica. Among the investigated catalysts, the 5 wt% Fe2P/γ-Al2O3 catalyst after calcination at 600 oC showed the highest FMK conversion and selectivity at the reaction temperature of 400 oC. |
