  • Extracted lignocellulosic material as an adsorbent and uses thereof
    Patent number: 11278865
    Abstract: According to an example aspect of the present invention, there is provided a method of removing dissolved contaminants from an aqueous liquid. The aqueous liquid is contacted with an adsorbent which comprises a finely divided lignocellulosic material, which has been subjected to extraction to remove hemicellulose and/or other components therefrom, to bind at least a portion of the organic compounds to the adsorbent. Furthermore, the invention relates to a method for removing or separating dissolved contaminants from a liquid and to a method for producing a liquid containing hemicellulose and/or an adsorbent containing lignin and/or other components. In particular the invention concerns the use of an adsorbent lignocellulosic material for removing dissolved contaminants from a liquid.

  • Recovery of xylose
    Patent number: 6872316
    Abstract: The invention relates to a process of producing a xylose solution from a biomass hydrolysate by subjecting the biomass hydrolysate to nanofiltration and recovering as the nanofiltration permeate a solution enriched in xylose. The biomass hydrolysate used as starting material is typically a spent liquor obtained from a pulping process.
