  • Patent number: 7378266
    Abstract: Improved processes for extracting polyhydroxyalkanoate from a biomass containing the polyhydroxyalkanoate including the steps of: combining the biomass containing the polyhydroxyalkanoate with a solvent selected from lower chain ketones, and mixtures thereof to form a biomass liquor wherein the biomass liquor comprises less than about 25% water; mixing the biomass liquor for from about 10 to about 300 minutes at a temperature in the range of from about 70° C. to about 120° C.; separating the polyhydroxyalkanoate from the biomass liquor to form a PHA-enriched liquor, wherein the separating occurs at a temperature of at least about 40° C.; mixing the PHA-enriched liquor with water to form precipitated polyhydroxyalkanoate and an impure solvent liquor, wherein the water is mixed with the PHA-enriched liquor in the ratio of from at least about 0.4-1 parts of water to one part solvent; and recovering the precipitated polyhydroxyalkanoate from the impure solvent liquor.
    Type: Grant

  • Publication number: 20070238905
    Abstract: Processes for converting glycerol to alkyl glycerol ethers that involve providing glycerol, alkyl alcohol and an etherification catalyst, providing an etherification reactor and, adding the glycerol, alkyl alcohol and etherification catalyst to the etherification reactor and reacting the glycerol, alkyl alcohol and etherification catalyst in the etherification reactor to obtain a reaction product comprising alkyl glycerol ethers.

  • Patent number: 7226765
    Abstract: Processes for the extraction of PHAs from biomass, said processes comprising: combining the biomass containing the PHAs with a single main solvent to form a biomass liquor; heating the biomass liquor to at least partially solubilize the PHAs from the biomass to form a PHA liquor; separating the biomass from the PHA liquor to form a PHA-enriched liquor; evaporating from 0% to about 50% of the single main solvent from the PHA-enriched liquor to form a solvent vapor and a concentrated PHA-enriched liquor; and cooling the concentrated PHA-enriched liquor to form precipitated PHAs and an impure solvent liquor. Optionally, further recovering the precipitated PHAs from the impure solvent liquor by filtration under pressure. A PHA-enriched liquor and a concentrated PHA-enriched liquor.

  • Patent number: 7153928
    Abstract: The present invention provides a method for easily obtaining a biodegradable polyhydroxyalkanoate by a solvent extraction method. A method for producing a polyhydroxyalkanoate crystal comprises mixing a solution of a polyhydroxyalkanoate in a good solvent with a poor solvent at 50 to 130° C. to precipitate a polyhydroxyalkanoate.

  • Patent number: 7118897
    Abstract: The invention relates to processes for extracting polyhydroxyalkanoate from a biomass, comprising admixing the biomass with an organic solvent for from 1 second to 15 minutes at a first temperature of from 5° C. below the melting point of the polyhydroxyalkanoate to 10° C. above the melting point of the polyhydroxyalkanoate and at a pressure of from 1 bar to 10 bar to provide a composition comprising the organic solvent and polyhydroxyalkanoate.
    Type: Grant

  • Patent number: 7098298
    Abstract: The present invention provides a method for conveniently obtaining a biodegradable polyhydroxyalkanoate by a solvent extraction method. A method for producing a polyhydroxyalkanoate crystal comprises precipitating a polyhydroxyalkanoate crystal using a monohydric alcohol having 4 to 10 carbon atoms as a extraction solvent, keeping a polyhydroxyalkanoate solution containing 0.1 to 10% by weight of water relative to the total amount of the solution warm at 70° C. or higher, and cooling the solution to below 70° C.
