  • Continuous countercurrent enzymatic hydrolysis of pretreated biomass at high solids concentrations
    Patent number: 9902982
    Abstract: The invention provides a continuous process for enzymatic hydrolysis of pretreated biomass, the process comprising: providing a pretreated lignocellulosic biomass feed material containing cellulose; introducing the pretreated lignocellulosic biomass feed material to a mechanical-treatment unit containing one or more decompression regions configured to release pressure; introducing a liquid solution containing cellulase enzymes to one or more decompression regions in the mechanical-treatment unit, wherein the liquid solution enters void spaces between fibers of the pretreated lignocellulosic biomass feed material, to form enzyme-containing cellulose-rich solids; and retaining the enzyme-containing cellulose-rich solids under effective hydrolysis conditions to hydrolyze at least some of the cellulose to glucose. Various apparatus configurations are disclosed for the mechanical-treatment unit.
