Patent ID: 10960401

Abstract:
A process for the decomposition of biomass-material includes subjecting a lignocellulose-containing biomass-material to comminution, subjecting the comminuted lignocellulose-containing biomass-material to a sifting to separate from the comminuted lignocellulose-containing biomass-material a fraction of small-particles, and subjecting the remaining comminuted lignocellulose-containing biomass-material to a pretreatment. Before, during, or after the pretreatment, small particles can be added to the remaining comminuted lignocellulose-containing biomass-material. Optionally, the small particles can be added continuously during the pretreatment. The addition of small particles decreases friction of the remaining comminuted lignocellulose-containing biomass-material results in decreased process time, energy savings, and reduced production costs.
