Abstract
The invention relates to a process for transformation of lignocellulosic biomass or cellulose that uses tungsten-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. The use of these catalysts makes it possible to obtain directly lactic acid with high selectivity while limiting the production of oligosaccharides and soluble polymers.
