Influence of Synthesis Conditions on Catalytic Performance of Ni/CeO₂ in Aqueous-Phase Hydrogenolysis of Glycerol without External Hydrogen Input.

ABSTRACT: The aqueous-phase hydrogenolysis of glycerol was studied in Ni/CeO₂ catalytic systems prepared by incipient wetness impregnation. The operating conditions were 34 bar, 227 ºC, 5 wt.% of glycerol, and a W/m_glycerol = 20 g catalyst min/g glycerol without a hydrogen supply. The effect of the catalyst preparation conditions on the catalytic activity and physicochemical properties of the catalysts was assessed, particularly the calcination temperature of the support, the calcination temperature of the catalyst, and the Ni content. The physicochemical properties of the catalysts were determined by N₂ adsorption, H₂-TPR, NH₃-TPD, and XRD, among other techniques. A relevant increase in acidity was observed when increasing the nickel content up
