  • Patent number: 10351770
    Abstract: Polysaccharides may be partially oxidized by oxidative opening of a monosaccharide unit while still retaining glycosidic bonds. Such polysaccharides may be further functionalized with an amine moiety at a site of oxidative opening. Polysaccharides that are partially oxidized and amine-functionalized in this manner may be combined with an aqueous liquid to form compositions suitable for stabilizing clays in clay-containing formations. Clay stabilization may promote reduced swelling of the clays in the presence of water.

  • Publication number: 20170166462
    Abstract: The invention is directed to compounds, compositions and methods for the removal of contaminants from fluids and, in particular sulfates and/or metals from industrial waste water. Compounds and compositions of the invention contain polysaccharides and other organic molecules. These flocculating agents are safe and effective, requiring no special handling procedures. Flocculation compounds include biopolymers of dextran, modified dextran and blends of dextrans, plus other organic and/or inorganic molecules. With the addition of flocculants of the invention to waste water, contaminants such as sulfate and toxic heavy metals can be safely, easily and efficiently removed.
