METHOD OF PROCESSING LIGNOCELLULOSIC FEEDSTOCK FOR ENHANCED XYLOSE AND ETHANOL PRODUCTION |
摘要 |
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 hemicelluloses 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. |
