  • Patent number: 9651304
    Abstract: A pretreatment for use with systems and methods for extracting and separating a bio-molecule, such as a lipid and/or a protein, from a biomass includes the step of contacting the biomass with a drying gas to substantially dewater the biomass to 20% water content by mass or less. Such pretreated biomass, mixed with one or more compressed liquefied gas solvents, may then be introduced into individual filter cells in a rotary pressure filter to separate lipids from proteins.

  • Patent number: 6844420
    Abstract: This invention is directed to a method of preparing a natural resin by liquefying wood, bark, forest residues, wood industry residues, or other biomass using rapid destructive distillation (fast pyrolysis). Fast pyrolysis produces both vapors and char from biomass, and following removal of the char from the product vapors, a liquid pitch product is recovered and processed by distillation, evaporation, or a combination thereof, in order to obtain a natural resin which may be in either liquid or solid form. The natural resin comprises a total phenolic content from about 30% to about 80% (w/w), and is a highly-reactive ligninic compound that has been found to be suitable for use within resin formulations without requiring any further extraction or fractionation procedures. Resins comprising up to 60% natural resin have been prepared and tested in board production and found to exhibit similar properties associated with commercially available resins.

  • Patent number: 5698667
    Abstract: A process for extracting volatile organic compounds and pitch from wood particulates, thereby virtually eliminating the emission of volatile organic compounds into the atmosphere during the processing of wood particulates into commercially useful products, such as oriented strandboard, particle board, chipboard veneers, and pulp and paper products. The removal of pitch permits the production of pulps of higher brightness, requiring less chemical bleaching agents. Moreover, removal of pitch eliminates pitch scale formation in pulp mills and on pulp and paper machines with resultant improved efficiencies and reduced use of pitch treatment chemicals. In the extraction process, a solvent or blend of solvents, leach wood extractives, including volatile organic compounds and pitch, from the wood particulates to produce a miscella. The miscella is separated from the leached wood particulates and solvent contained in the miscella is recovered and recycled for reuse.
