Bio-oils Hydrodeoxygenation: Adsorption of Phenolic Molecules on Oxidic Catalyst Supports
Abstract
The interaction of phenol, anisole, and guaiacol, representatives of oxygenate functions present in pyrolysis bio-oils, with oxides such as silica, alumina (pure or doped with K or F), and silica−alumina is investigated by infrared spectroscopy. While phenolic type compounds mainly interact via H-bonding with silica, chemisorption is their main mode of adsorption on alumina. Besides, guaiacol interacts very strongly by forming doubly anchored phenates instead of monoanchored ones with phenol and anisole. At temperatures typical of hydrodeoxygenation (HDO) operating conditions (∼673 K), the phenate type species cover 2/3 of the alumina surface. This study clearly indicates that substantial carbon deposition could take place on alumina-supported HDO catalysts. Hence, this suggests that silica-based supports should be considered as potential candidates to design HDO catalyst with better stability.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
