Abstract (en)
[origin: WO2012022853A1] The invention relates to a process for converting lignocellulosic or cellulose biomass using heterogeneous catalysts based on tungsten oxide dispersed on a support based on oxides, preferably based on oxide(s) of aluminium and/or of zirconium and/or of titanium and/or of niobium and containing an element in the particular metal state. The use of these catalysts makes it possible to directly obtain upgradable products containing three carbon atoms, in particular hydroxyacetone and propylene glycol with high selectivity.
