Screening of promoted CeO2/Al2O3 catalysts in aqueous phase glycerol reforming and hydrogenolysis into 1,2-propanediol

A series of promoted CeO2/Al2O3 catalysts (10Cu-90CeO2/Al2O3, 10Ni-90CeO2/Al2O3, 10Co-90CeO2/Al2O3) were synthesized via method of impregnation and later calcined at 600 ℃. Those catalysts were formerly tested for their physicochemical properties by X-ray diffraction (XRD), H2-temperature programme...
