The invention relates to a method for converting a starting material selected from sugars or sugar alcohols, alone or in a mixture, into mono-or poly-oxygenated compounds, wherein said starting material is contacted with at least one heterogeneous catalyst comprising a compound selected from the group consisting of compounds having the formula ABO under a reducing atmosphere at a temperature of between 100 ℃ and 300 ℃ and a pressure of between 0.1MPa and 50MPa 3 And a support of an oxide of an element selected from lanthanum, neodymium, yttrium and cerium, wherein a is selected from the elements Mg, Ca, Sr and Ba and B is selected from the elements Fe, Mn, Ti and Zr, alone or in a mixture, said oxide being possibly doped with at least one element selected from the group consisting of alkali metals, alkaline earth metals and rare earth metals. |
