  • Method of processing lignocellulosic feedstock for enhanced xylose and ethanol production
    Patent number: 7993463
    Abstract: The present invention provides a method of producing xylose from lignocellulosic feedstock. The method comprises disrupting lignocellulosic feedstock; leaching the lignocellulosic feedstock by contacting the feedstock with at least one aqueous solution for a period greater than about 2 minutes to produce a leached feedstock and a leachate; removing the leachate from the leached feedstock; acidifying the leached feedstock to a pH between about 0.5 and about 3 to produce an acidified feedstock, and; reacting the acidified feedstock under conditions which disrupt fiber structure and hydrolyze a portion of hemicellulose and cellulose of the acidified feedstock, to produce a composition comprising xylose and a pretreated feedstock. The xylose may be purified from the pretreated feedstock or it may be converted to ethanol with the pretreated feedstock.
    Type: Grant
    Filed: January 31, 2007
    Date of Patent: August 9, 2011
    Assignee: Iogen Energy Corporation
    Inventors: Robert Griffin, Colin Nicholson, Corinne Mott, Jeffrey S. Tolan, Vijay Anand
