Title:
METHOD FOR PRETREATING PLANT STARTING MATERIAL FOR THE PRODUCTION, FROM SACCHARIFEROUS AND LIGNOCELLULOSIC RESOURCES, OF BIOETHANOL AND/OR OF SUGAR, AND PLANT
Document Type and Number:
WIPO Patent Application WO/2010/006840
Kind Code:
A3
Abstract:
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 canbe 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.
