The invention relates to a method for the conversion of aqueous solutions of lignocellulosic solids having a solid content of between 1 and 20 % in terms of dry material, wherein said method comprises the step a) of compressing said solution in order to separate the liquid phase present in and between the solids of the compressed solid phase, and the step b) of extracting at least said liquid phase, said liquid phase being further homogenised by thermal and/or chemical processing and re-injected onto the compressed solid phase.
L'invention décrit un procédé de conversion de solution aqueuses de solides lignocellulosiques comprenant une teneur en solides comprise entre 1 et 20% de matière sèche, ledit procédé comprenant une étape a) de compression de ladite solution de manière à séparer la phase liquide présente dans et entre les solides de la phase solide compressée et une étape b) d'extraction d'au moins la phase liquide, ladite phase liquide étant ensuite homogénéisée par des traitements thermiques et / ou chimiques et réinjectée sur la phase solide compressée.
