Supported palladium catalysts for the selective oxidation of glycerol have been prepared by the extractive-pyrolytic method. For the preparation of catalysts, Al2O3, Y2O3, C, Pyrex were used as carriers. The main glycerol oxidation product in the presence of the obtained catalysts was glyceric acid. The by-products were tartronic, lactic, glycolic and oxalic acids. After optimizing the glycerol oxidation process, selective glyceric acid production conditions were found for the two most active new catalysts 1.25 % Pd/Al2O3 and 2.5 % Pd/Al2O3.
