Abstract
Hydrodeoxygenation (HDO) of 1-naphthol catalyzed by Mo γ- Al 2O 3 and Ni-Mo γ- Al 2O 3 was investigated with a flow reactor operated at 225 °C and 120 atm. The oxidic forms of the catalysts were more active than the sulfidic forms. The catalysts were deactivated during operation, evidently by water formed in the HDO reaction. The selectivity changed markedly during the deactivation, the HDO reactions becoming markedly slower and the hydrogenation reactions only slightly slower. The deactivated oxidic and sulfidic catalysts could be reversibly regenerated by treatment with H 2 and H 2S in H 2, respectively. The catalyst surfaces are suggested to incorporate two kinds of catalytic sites, one catalyzing direct HDO, the other aromatic ring hydrogenation. These sites are suggested to be anion vacancies, susceptible to inhibition by bonding of H 2O.
