  • 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.
