  • Method of making alkyl esters using glycerin
    Patent number: 7087771
    Abstract: A method for making alkyl esters (e.g., methyl ester), such as biodiesel, from an oil source is described. The method involves converting the free fatty acids of the oil source into a mixture of mono-, di-, and tri-glycerides and subsequently transesterifying the newly formed glycerides as well as the originally present glycerides into fatty acid alkyl esters.
    Type: Grant
    Filed: September 29, 2004
    Date of Patent: August 8, 2006
    Assignee: Biosource America, Inc.
    Inventors: Franz J. Luxem, Jenifer Heydinger Galante, William M. Troy, Randal J. Bernhardt
  • Method of making alkyl esters
    Publication number: 20040254387
    Abstract: A method for making biodiesel from a vegetable oil source is described. The method involves simultaneously reacting the free fatty acids and glycerides of the vegetable oil source with methanol, under pressure up to 250 psig, into fatty acid alkyl esters for use as biodiesel. The conversion is catalyzed by an acid at temperatures between about 80° C. to about 200° C.

  • Method of making alkyl esters using glycerin
    Patent number: 6822105
    Abstract: A method for making alkylesters, or methylester specifically, such as biodiesel, from an oil source is described. The method involves converting the free fatty acids of the oil source into a mixture of mono-, di-, and tri-glycerides and subsequently transesterifying the newly formed glycerides as well as the originally present glycerides into fatty acid alkyl esters.

  • Method of making alkyl esters using pressure
    Patent number: 6768015
    Abstract: A method for making alkyl esters, or methylester specifically, such as biodiesel, from an oil source is described. The method involves simultaneously reacting the free fatty acids and glycerides of the oil source with methanol, under pressure up to 500 psia, into fatty acid alkyl esters. The conversion is catalyzed by an acid at temperatures between about 80° C. to about 200° C.
