  • Biodiesel cold filtration process
    Patent number: 11326115
    Abstract: An improved biodiesel production process includes the steps of processing a feedstock to produce biodiesel, cooling the biodiesel so as to form sediment, and filtering the biodiesel to remove the sediment. The resulting biodiesel from the cold filtration process avoids problems of sediment formation during storage and transportation.
    Type: Grant
    Filed: July 27, 2015
    Date of Patent: May 10, 2022
    Assignee: Renewable Energy Group, Inc.
    Inventors: Myron Francis Danzer, Timothy L Ely, Scott Alan Kingery, John Mostek, Matthew Leonard Schultes, Wayne William McCalley, William Michael McDonald
