  • Process for liquefaction of lignocellulosic biomass
    Patent number: 10150843
    Abstract: Methods and systems are provided for improved liquefaction of a lignocellulosic biomass. The methods include reacting a lignocellulosic biomass slurry at mild conditions for a short period to produce a first reaction mixture having a reduced viscosity as compared to the lignocellulosic biomass slurry and that is substantially free of levulinic acid and hydroxymethylfurfural. The methods further include separating the first reaction mixture into a solid fraction and a liquid fraction, the solid fraction having a majority of lignin from the lignocellulosic biomass slurry and the liquid fraction having a majority of hemicellulose and greater than about 30% by weight of cellulose from the lignocellulosic biomass slurry. The method advantageously prevents or eliminates the formation of tar and/or char.
