Abstract
A process for the production of an intermediate product from a lignocellulosic raw material that is intended for the production of ethanol, which process includes pulping the raw material in an extruder at a temperature of between 60° C. and 180° C., in the presence of a quantity of water that represents between 200% and 450% of the mass of the raw material and preferably in the presence of a strong acid or a strong base that is weakly concentrated. An intermediate product can be obtained by this process for producing ethanol.
