Method For Pretreating Plant Starting Material For The Production, From Sacchariferous And Lignocellulosic Resources, Of Bioethanol And Of Sugar, And Plant

摘要

The invention proposes a method for pretreating plant starting material for the purpose of producing bioethanol and/or sugar by means of a common chamber (12), characterized in that: - during one period, the plant material (MP), introduced into the common pretreatment chamber, is a lignocellulosic plant starting material, the pretreatment of which is aimed at separating the cellulose, the hemicelluloses and the lignins so as to obtain a pretreated plant material that can be hydrolysed and fermented for the production of bioethanol; - during another period, the plant material (MP), introduced into the common pretreatment chamber, is a sacchariferous plant starting material, the pretreatment of which is aimed at extracting therefrom, by diffusion, a sugar juice for the production of sugar and/or of bioethanol.
