Effect of Metal Loading in Unpromoted and Promoted CoMo/Al2O3–TiO2 Catalysts for the Hydrodeoxygenation of Phenol
J. Andrés Tavizón-Pozos,C.E. Santolalla-Vargas,Omar Uriel Valdés-Martínez,José Antonio de los Reyes Heredia +3 more
TL;DR: In this paper, the effects of changes in the supported active phase concentration over titania containing mixed oxides catalysts for hydrodeoxygenation (HDO) were reported. And the results showed that the increase in Mo loading led to an increase in the amount of oxide Mo species with octahedral coordination, which produced more active sites and augmented the catalytic activity.
