Abstract
The invention relates to a process for transformation of lignocellulosic biomass or cellulose using heterogeneous catalysts that are based on tin oxide and/or antimony oxide, dispersed on a substrate and containing at least one element in the particular metal state. The use of these catalysts makes it possible to obtain directly upgradable products, in particular hydroxyacetone and propylene glycol with high selectivity.
