摘要:
The invention relates to a method for processing a lignocellulose or cellulose biomass using heterogeneous tungsten-based catalysts dispersed on a support based on (an) oxide(s), preferably (an) aluminium and/or zirconium and/or titanium and/or niobium oxide(s). The use of said catalysts results in the direct and highly selective production of lactic acid, while limiting the production of oligosaccharides and of soluble polymers.
