Abstract
The invention concerns a method for converting a feedstock selected from sugars or sugar alcohols, alone or in a mixture, into mono- or polyoxygenated compounds, wherein the feedstock is contacted with at least one heterogeneous catalyst comprising a support selected from perovskites of formula ABO3, in which A is selected from the elements Mg, Ca, Sr and Ba and B is selected from the elements Fe, Mn, Ti and Zr, and the oxides of elements selected from lanthanum, neodymium, yttrium and cerium, alone or in a mixture, which oxides can be doped with at least one element selected from alkali metals, alkaline earths and rare earths, in a reducing atmosphere, at a temperature of 100° C. to 300° C. and at a pressure of 0.1 MPa to 50 MPa.
