Abstract:
The invention relates to a process for transformation of lignoceliulosic biomass or cellulose that uses tungsten-oxide-based heterogeneous catalysts that are dispersed on an oxide-based substrate, preferably with a base of oxide(s) of aluminum and/or zirconium and/or titanium and/or niobium and containing an element in the particular metallic state. The use of these catalysts makes it possible to obtain directly upgradable products containing three carbon atoms, in particular hydroxyacetone and propylene glycol with high selectivity.
