  • Production of hydrophobic fibers
    Patent number: 5705216
    Abstract: A woody or non-woody biomass is delignified through continuous extrusion technology, utilizing high-pressure steam to break down complex biomass materials. The process is useful to form a hydrophobic fiber material for use as an extrusion filler, a plastics modifier, and in the papermaking arts. Alternatively, the process is useful for preparing dietary feeds for ruminant animals, as well as to produce a broad range of alcohols or polymers from lignocellulosic substrates.
    Type: Grant
    Filed: August 11, 1995
    Date of Patent: January 6, 1998
    Inventor: George J. Tyson
  • Delignification of non-woody biomass
    Patent number: 5023097
    Abstract: A non-woody biomass is delignified through extrusion technology, utilizing hydrogen peroxide and an alkali agent, to break down complex biomass materials. The process is useful in forming a highly absorbant fiber material for use as a dietary fiber or an absorbant fiber. Alternatively, the process is useful for preparing dietary feeds for ruminant animals, as well as produce a broad range of alcohols or polymers from the non-woody lignocellulosic substrate.
