  • Stabilization of lignin fibers
    Patent number: 10316051
    Abstract: A process for stabilizing lignin fibers, stabilized lignin fibers made by the process and carbonized fibers made from stabilized lignin fibers. The process includes heating lignin fibers to a temperature ranging from about 100° to about 220° C. while the fibers are in an atmosphere of air and HCl gas, generated as air is bubbled through concentrated hydrochloric acid for a period of time sufficient to stabilize the lignin fibers.
    Type: Grant
    Filed: July 1, 2015
    Date of Patent: June 11, 2019
    Assignee: Prisma Renewable Composites, LLC
    Inventors: Zhongren Yue, Ahmad D. Vakili
