Abstract
The invention relates to a process for treating a lignocellulosic biomass comprising a solids content of not more than 80% by weight, said process comprising the use of at least one reactor (9,14) for treating said biomass, in which the or at least one of said reactors is fed with biomass via a feed means (6,11) creating a pressure increase between the biomass inlet and the biomass outlet of said feed means, in which said feed means is washed by circulation of a washing fluid between a washing inlet (7,12) and a washing outlet (8,13). According to the process, at least a portion of the washing fluid (8,13) exiting the fluid outlet of the at least one feed means (6,11) is reintroduced into the washing inlet of the same feed means or of another of said feed means.
