Definitions

  • the present invention relates to a process for producing an intermediate product for the production of ethanol from a lignocellulosic raw material.
  • ecofuels there are various techniques for producing ecofuels, such as the production of oil, alcohol or gaseous fuels from plant or animal biomass, or from industrial or community waste.
  • agrofuels are developed as ethanol from fermentations of sugars from cereals, wheat or corn, or beetroot.
  • lignocellulosic biomass is chemically pretreated to hydrolyze hemicelluloses and make cellulose accessible.
  • the invention relates to a method for producing an intermediate product from a lignocellulosic raw material, intended for the production of ethanol, characterized in that it consists in defibrating said raw material in an extruder at a temperature between 60 0 C and 180 0 C and in the presence of a quantity of water representing between 200% and 450% of the mass of said raw material.
  • the process according to the invention consists in defibrating the lignocellulosic raw material in an extruder at a temperature of between 60 ° C. and 180 ° C., in the presence of a quantity of water representing between 200% and 450% of the mass of the product. said raw material and in the presence of a strong acid or a strong base weakly concentrated relative to the amount of water, namely at a concentration of between 0.5% and 4% relative to the volume of water.
  • the invention also relates to the intermediate product obtained by the implementation of this process.
  • - noble vegetable fibers for example hemp or flax
  • - energy crops eg miscanthus, switchgrass, willow, poplar
  • the lignocellulosic raw material is also defibrated in the presence of a strong acid or a strong base at a concentration of between 0.5% and 4% relative to the volume of water.
  • An extruder is a device composed mainly of one or more worms rotating at a determined speed inside a cylindrical sleeve temperature regulated.
  • a twin-screw extruder is an extruder consisting of two cooperating screws rotating in the same direction and a sheath enveloping these two screws.
  • the two screws are identical and consist of modules that include a conveying element of the material provided with windows or slots cut in the threads.
  • the extruder makes it possible in a single step to carry out one or more operations, in particular the defibration of the lignocellulosic biomass by the combination of the compression and shearing actions which makes it possible to separate the fibers and to release the cellulose in the process. releasing lignin network, and the solubilization of hemicelluloses.
  • the temperature of the extruder is between 60 ° C. and 180 ° C., preferably between 90 ° C. and 120 ° C., and even more preferentially between 100 ° C. and 110 ° C.
  • the quantity of water used in the extruder is between 200% and 450% of the mass of said lignocellulosic raw material, preferably between 300% and 450%, even more preferably between 300% and 400% of the mass of the product. the lignocellulosic raw material.
  • the amount of strong acid or strong base is between 0.5% and 4% relative to the volume of water, preferably between 0.5 and 1.5%, more preferably between 0.8% and 1.2%. It may be, for example, hydrochloric acid, sulfuric acid or sodium hydroxide.
  • the strong acid can be mineral or organic.
  • the conjugation of these parameters, temperature, amount of water and / or amount of strong acid or strong base particular, provides a lignocellulosic intermediate product that can be hydrolyzed at a particularly high rate.
  • An example of a particularly suitable method according to the invention comprises the following steps:
  • Tests were carried out using this method by varying the parameters of temperature, amount of water and the presence or absence of a strong acid or a strong base.
