  • Production of biodiesel, cellulosic sugars, and peptides from the simultaneous esterification and alcoholysis/hydrolysis of oil-containing materials with cellulosic and peptidic content
    Patent number: 8212062
    Abstract: The present invention relates to a method for producing fatty acid alkyl esters as well as cellulosic simplified sugars, shortened protein polymers, amino acids, or combination thereof resulting from the simultaneous esterification and hydrolysis, alcoholysis, or both of algae and other oil containing materials containing free fatty acids (FFA), glycerides, or combination thereof as well as polysaccharides, cellulose, hemicellulose, lignocellulose, protein polymers, or combination thereof in presences of an alcohol and an acid catalyst.
    Type: Grant
    Filed: April 2, 2008
    Date of Patent: July 3, 2012
    Assignee: Inventure Chemical, Inc.
    Inventors: William Wes Berry, Mark G. Tegen, Stephen L. Hillis

  • PARTIAL PRESSURE DISTILLATION PROCESS
    Publication number: 20110162951
    Abstract: A method for separating at least one volatile component such as an alkyl ester, an alcohol, hydroxymethylfuran, dimethylfuran, methyl tetrahydrofuran, a polyhydric alcohol, or a reduction product of a polyhydric alcohol from at least one non-volatile component such as a saccharide, a peptide, or ash in a mixture is disclosed. The method includes heating the mixture to a temperature of between 150-250° C. and contacting the mixture with a superheated distillation alcohol in a gaseous or vapor phase. The distillation alcohol pressure imparts partial vapor pressure on the at least one volatile component of the mixture and distills at least a portion of the at least one volatile component from the mixture.
