Patents by Inventor Gerald Gruesendorf

Gerald Gruesendorf has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 8668750
    Abstract: A denatured fuel ethanol composition for blending with fuels, including gasoline and diesel fuel. The composition includes an ethanol composition comprising at least 92 wt. % ethanol; and from 95 wppm to 1,000 wppm isopropanol; and at least 1.96 vol. % fuel denaturant.
    Type: Grant
    Filed: August 3, 2011
    Date of Patent: March 11, 2014
    Assignee: Celanese International Corporation
    Inventors: Victor Johnston, Lincoln Sarager, R. Jay Warner, Heiko Weiner, Gerald Gruesendorf, Trinity Horton, Radmila Jevtic
  • Patent number: 8552226
    Abstract: Ethanol production from the hydrogenation of acetic acid requires energy to drive the hydrogenation reaction and the purification of the crude ethanol product. Heat integration process to recover heat from one part of the production process to be used within the process improves efficiencies and reduces costs.
    Type: Grant

  • Patent number: 8552225
    Abstract: Vaporizing acetic acid in the presence of hydrogen to provide a vapor feed stream for a hydrogenation process that produces ethanol. The vaporizer forms a vapor feed stream and a blowdown stream having a weight ratio of the vapor feed stream to the blowdown stream of at least 2:1. The acetic acid may vaporized at a temperature below acetic acid's boiling point at the operating pressure of the reactor. The hydrogenation process produces a crude ethanol product and ethanol is separated from the crude product. In addition, at least one recycle stream comprising acetic acid and less than 1.0 wt. % compounds having a boiling point higher than acetic acid, may also be separated. The recycle streams may be introduced to the vaporizer along with acetic acid to form the vapor feed stream.
