Synthesis and characterization of cerium and aluminium oxides and catalytic evaluation in the dehydration of glycerol

This work shows the study of two catalysts, -Pt/CeO2 y Pt/g-Al2O3, to transform the glycerol, through dehydration reaction, highlighting the synthesis and physicochemical characterization of the cerium and aluminum oxides contans platinum. Prliminary results shw the activity catalytic favored selectivity to acrolein in the case of Pt/g-Al2O3 catalyst, and the selectivity is to hydroxiacetone in case of Pt/CeO2 catalysts.

Keywords: glycerol, dehydratiation, acrolein, Pt/ g-Al2O3, Pt/CeO2.
