  • METHODS FOR PRODUCING A HYDROLYSATE AND ETHANOL FROM LIGNOCELLULOSIC MATERIALS
    Publication number: 20080227161
    Abstract: A method for producing a hydrolysate from lignocellulosic materials generally includes fiberizing the lignocellulosic materials, separating the lignocellulosic materials into at least a first portion and a second portion, wherein at least the first portion includes lignin, treating the first portion to deactivate at least a portion of the lignin in the first portion, re-combining the first and second portions after treating the first portion, and hydrolyzing the lignocellulosic materials with enzymes to produce a hydrolysate.
