Method for pretreating primary plant material for production from saccharide and lignocellulosic, biotanol and / or sugar resources, and plant

摘要

A method for pretreating plant starting material for the purpose of producing bioethanol and/or sugar via a common chamber (12), is characterized in that: during one period, the plant material (MP), introduced into the common pretreatment chamber, is a lignocellulosic plant starting material, whose pretreatment is aimed at separating the cellulose, the hemicelluloses and the lignins so as to obtain a pretreated plant material that can be hydrolyzed 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, whose pretreatment is aimed at extracting therefrom, by diffusion, a sugar juice for the production of sugar and/or of bioethanol.
