Hydrodeoxygenation of bio-oil over Pt-based supported catalysts: importance of mesopores and acidity of the support to compounds with different oxygen contents

The importance of the acidity and mesoporous structure to the hydrodeoxygenation activity of catalysts for bio-oil upgrading was investigated. By testing three model bio-oil compounds, we showed that catalysts with a strong acidity (e.g. ZSM-5) have a high hydrodeoxygenation activity, while the mesoporous structure of the support can further improve the catalytic performance of ZSM-5.
