The hydrodeoxygenation of various bio-oil model compounds (anisole, m-cresol and guaiacol) over Pt/HBEA and the evolution of surface species is investigated. Depending on the functional group, different surface species are formed when the compounds are adsorbed in the presence of Lewis acid sites. For anisole, the methoxy group is decomposed to form phenate species. The methyl and methoxy group remains intact on m-cresol and guaiacol to form cresolate and methoxy phenate species, respectively. The position of these functional groups have a strong influence in the degree of hydrodeoxygenation due to steric hindrance. Based on operando transmission FTIR spectroscopy, a timeline for the formation of polynuclear aromatics and catalyst deactivation is constructed, which is also dependent on the substituents. The slow deactivation rate and low carbon content on Pt/HBEA is discussed.
