  • Patent number: 10329593
    Abstract: Described herein is a process for producing saccharides and ethanol from biomass feedstock that includes (a) producing an enzyme composition by culturing a fungal strain(s) in the presence of a lignocellulosic medium, (b) using the enzyme composition to saccharify the biomass feedstock, and (c) fermenting the saccharified biomass feedstock to produce ethanol. The process is scalable and, in certain aspects, is capable of being deployed on farms, thereby allowing local production of saccharides and ethanol and resulting in a reduction of energy and other costs for farm operators. Optional steps to improve the biomass-to-fuel conversion efficiency are also contemplated, as are uses for byproducts of the process described herein.

  • Publication number: 20090188639
    Abstract: A water-soluble interjacent complex that includes a first water-soluble polymer and one or more water-soluble monomers polymerized to form a second water-soluble polymer in the presence of the first water-soluble polymer. The water-soluble interjacent complex forms a solution in water that is free of insoluble polymer particles. The interjacent complexes may be used to treat a waste sludge by adding an effective amount thereof to the waste sludge. The interjacent complexes may also be used in making paper by adding an effective amount thereof to a pulp or a forming sheet at a suitable location on a paper making machine. The interjacent complexes may further be used as a rheology modifier in aqueous systems by adding an effective amount thereof to an aqueous medium to effect a desired viscosity, rheology, or flow curve property.

  • Patent number: 7241508
    Abstract: An improved pigment-coated paper is provided which enables the use of a non-acidic basesheet in the manufacture of a fragrance release paper. The non-acidic basesheet, compared to the conventionally used acidic basesheet, is brighter and less brittle, and therefore imparts improved visual effects and reduces the likelihood of cracking. The clay-based coating composition is mildly alkaline when wet (pH between 7.5 and 8.5) and upon drying on the basesheet, becomes mildly acidic (pH between 6.0 and 7.0). A method of making the improved pigment-coated paper using a non-acidic basesheet in the manufacture of a fragrance release paper is provided, comprising the steps of preparing the basesheet, applying the premixed pigment coating composition using rollers and blade leveling devices, and drying the pigment coating composition. A fragrance sample construction, for use in magazines, catalogs, leaflets, etc.
