Etude des possibilités de production d'éthanol hémicellulosique dans le cadre d'une bioraffinerie papetière.

Abstract : Decreasing the consumption of crude oil derivatives has become one of the main world issues of the 21st century. The only green substitute for gasoline potentially available in large quantities today is bioethanol, but its production has to be limited as it is produced from crops. It is therefore important to develop the production of second generation ethanol, which consists in using lignocellulosic biomass as raw material to avoid to compete with food resources. Second generation ethanol is still at experimental scale nowadays. This thesis deals with the specific case of the production of ethanol from hemicelluloses in a kraft pulp mill. In pulp mills, hemicelluloses, which make up 20 to 30% of the wood, are not value added. It is proposed to extract them from wood prior to the kraft treatment and to ferment them into ethanol. The study talks more specifically of the optimisation of the global process from the woodchip to the ethanol.
