제목 Upgrading bio-oil model compounds over bifunctional Ru/HZSM-5 catalysts
초록 Hydrodeoxygenation(HDO) of vanillin as a bio-oil model compound was performed using bifunctional Ru loaded HZSM-5 catalysts with different metal loadings and Si/Al2 ratios in n-octane/water biphasic system. Both the reaction pathway and product distribution were influenced by the metal/acid balance of the catalysts. Higher metal/acid ratio promoted Caryl-C cleavage reaction, resulting in the increased yield of cyclohexane. Synergetic effect of metal and acid sites was observed in the bifunctional catalyst, attaining as high as 40-fold increase of metal efficiency in the ring hydrogenation reaction, compared to lone metal site catalyst. The effect of solvent composition was evaluated, revealing that the presence of water promoted the overall HDO reaction. By balancing metal/acid and introducing appropriate solvent system, efficient catalytic system that minimized carbon loss and improved metal efficiency for vanillin HDO was obtained.
