  • Method of processing lignocellulosic material using a cationic compound
    Patent number: 10787687
    Abstract: The present disclosure relates to a method for obtaining sugar and lignin fractions from lignocellulosic materials and to a method for producing fermentation products using the sugars obtained from the lignocellulose. The present disclosure also relates to a method for improving the sugar yield in the enzymatic hydrolysate by introducing a pre-treatment step of hydrothermal hydrolysis with a delignification step using a cationic compound.
    Type: Grant
