摘要：

In this study, spherical gamma-Al2O3 supported metal and metal phosphide (Ni, Co, Ni2P and CoP) catalysts were successfully prepared by combining sol-gel and spray pyrolysis methods. First boehmite sol was prepared based on the Yoldas process and then the corresponding metal salts 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 gamma-Al2O3 supported metal and metal phosphide catalysts during spray pyrolysis process, the metal species were uniformly distributed in the mesoporous gamma-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 10 wt% Ni/gamma-Al2O3 catalyst after calcination at 800 degrees C showed the highest FMK conversion of 83.02% at the reaction temperature of 400 degrees C. The gas and liquid products were analyzed by gas chromatography (GC) with TCD/FID detectors and GC-MS, respectively, to determine the product compositions. (C) 2016 Elsevier Ltd.
