  • Bioderived heat transfer fluids and methods of making the same
    Patent number: 11725093
    Abstract: The present disclosure relates to a composition that includes a lignin-derived mixture that includes at least one of a dimer, a trimer, and/or a tetramer, where the composition is characterized by a thermal stability up to a maximum temperature between about 260° C. and about 300° C.
    Type: Grant
    Filed: September 1, 2020
    Date of Patent: August 15, 2023
    Assignee: Alliance for Sustainable Energy, LLC
    Inventors: Nicholas Earl Thornburg, Jacob S. Kruger
  • CONTINUOUS PROCESSING OF LIGNIN FOR REDUCED SOLVENT USAGE IN REDUCTIVE CATALYTIC FRACTIONATION
    Publication number: 20220411454
    Abstract: Described herein are devices and methods for the efficient and economic generation of lignin monomers from biomass. The provided devices and methods utilize reductive catalytic fractionation with an organic solvent to extract high-quality lignin from biomass and cleave specific lignin bonds to generate valuable lignin monomers with a relatively narrow product slate. Advantageously, the devices and methods described herein utilize solvent recycling, multiple solvolysis chambers with multiple biomass beds and/or physical agitation (e.g., use of a screw extruder) to reduce the amount of solvent required and increase economic efficiency and monomer yield.

  • Reversibly soluble bases for lignin oxidative depolymerization
    Patent number: 11530232
    Abstract: Disclosed herein are lignin valorization strategies that integrate thermochemical pretreatment strategies. Using methods disclosed herein, yields of greater than 40% of usable monomers are obtained from lignin in biomass. The monomers can be assimilated by strains of Pseudomonas putida.
