Methods and systems for producing sugars from carbohydrate-rich substrates |
| abstract |
A method for producing sugars from lignocellulosic biomass is provided. Lignocellulosic biomass is composed of lignocellulosic fibers which are hollow and primarily contain cellulose, hemicellulose and lignin. Lignin is concentrated in the outer fiber wall and glues the fibers into bundles, but the inner fiber wall has a much lower concentration of lignin and has more easily accessible cellulose and hemicellulose. This method uses vacuum infusion to infuse homogeneous reagents into the lumen (hollow center) of lignocellulosic fibers to hydrolyze the hemicellulose and cellulose to produce sugars and oligomers, and then uses cycles of vacuum pressure to pump these homogeneous reagents and sugars and oligomers into and out of the lumen. Some types of reagents are dilute acids, cellulase enzymes, hemicellulase enzymes, Fenton or Fenton-like reagents, and hydrogen peroxide. These reagents are homogenized by mixing the reagents with process water using turbulent mixing to produce a homogeneous reagent. |
