Hydrodeoxygenation of 1-naphthol: Activities and stabilities of molybdena and related catalysts

摘要: Hydrodeoxygenation (HDO) of 1-naphthol catalyzed by Moγ-Al2O3 and Ni-Moγ-Al2O3 was investigated with a flow reactor operated at 225 °C 120 atm. The oxidic forms the catalysts were more active than sulfidic forms. deactivated during operation, evidently water formed in HDO reaction. selectivity changed markedly deactivation, reactions becoming slower hydrogenation only slightly slower. could be reversibly regenerated treatment H2 H2S H2, respectively. catalyst surfaces are suggested to incorporate two kinds catalytic sites, one catalyzing direct HDO, other aromatic ring hydrogenation. These sites anion vacancies, susceptible inhibition bonding H2O.
