Several supported platinum catalysts were prepared by the extractive–pyrolytic method for the selective production of glyceric acid from glycerol. Al2O3, Y2O3, Lu2O3, ZrO2–Y2O3 TiO2, SG, Fe2O3, γ-AlO(OH) and C were used as the catalyst supports. Glycerol oxidation was performed in alkaline solutions and oxygen was used as the oxidant. The optimal catalyst preparation parameters and glycerol oxidation conditions to obtain glyceric acid were determined. The best result (57 % selectivity to glyceric acid with 92 % glycerol conversion) was achieved on a 4.8 % Pt/Al2O3 catalyst.
