Methods and Systems for Pretreatment of Biomass Solids

A method for the pretreatment of biomass solids includes hydrating the biomass solids to form a biomass slurry, shear treating the biomass solids, and hydrolyzing the biomass solids in the presence of reactive enzymes in a pressure hydrolysis zone. Shear treatment of the biomass solids reduces the p...

Beschreibung
Zusammenfassung:	A method for the pretreatment of biomass solids includes hydrating the biomass solids to form a biomass slurry, shear treating the biomass solids, and hydrolyzing the biomass solids in the presence of reactive enzymes in a pressure hydrolysis zone. Shear treatment of the biomass solids reduces the particle size of the biomass solids, modifies the particle or slurry morphology, and/or ruptures the cell walls of the biomass solids. The pressure hydrolysis zone includes a high-shear, high-pressure, low-temperature heat exchange and reaction zone and a low-pressure, low-temperature polishing zone. Sugars formed from the biomass solids treated in accordance with the methods described above may be used to produce various biofuels.
