Vapor phase hydrodeoxygenation and hydrogenation of m-cresol on silica supported Ni, Pd and Pt catalysts

highlights
• Hydrogenation and hydrodeoxygenation are the primary reactions for cresol conversion.
• Intrinsic activity of hydrogenation follows Ni• Oxygen removal is mainly through the direct deoxygenation path.
• Toluene is the major final product at full conversion of cresol.
• Increase of temperature improves hydrodeoxygenation and C–C hydrogenolysis.

Hydrodeoxygenation of m-cresol (a model compound of lignin derived phenolics in bio-oil) has been studied on silica supported Ni, Pd and Pt catalysts at 250 °C and atmospheric pressure. Hydrogenation (to 3-methylcyclohexanone and 3-methylcyclohexanol) and hydrodeoxygenation (to toluene) are the primary reactions over all catalysts. The intrinsic hydrogenation activity follows the order of Ni
