Аннотация: The hydroprocessing of various aromatic hydroxy acids (lignin oxidation products) using in situ formed MoO_x and WO_x catalysts is reported. Direct deoxygenation is the major route over MoO_x, while direct deoxygenation and decarboxylation routes occur simultaneously when using WO_x. The possibility for the selective production of phenol, cyclohexane, and xylenes is demonstrated.

Ключевые слова: hydrodeoxygenation, lignin, aromatic acid, phenols, molybdenum oxide, tungsten oxide.
