  • Process for dry fractionation of lignocellulosic biomass
    Patent number: 9879287
    Abstract: The process for the dry fractionation of lignocellulosic biomass of at least 50% by weight of lignins, cellulose and hemicelluloses. The biomass is fragmented to obtain an ultrafine powder. The process includes at least one step of separating a fraction enriched with cellulose and a fraction enriched with lignin, hemicelluloses and minerals by electrostatic sorting of the ultrafine particles. Preferably, the fraction separation step includes a step of triboelectrostatic charging of ultrafine particles and at least one step of deviating a path in the electric field of the charged particles to sort the particles.
