PRETREATMENT AND FRACTIONATION OF LIGNOCELLULOSIC BIOMASS |
| 摘要 |
Method and apparatus for enhanced production of sugars and lignin via fractionation of lignocellulosic biomass through sequential ionic liquid pretreatment and mild alkaline treatment. The resulting biomass is easily fractionated and amenable to efficient and rapid hydrolysis and catalytic conversion to valuable products with high recovery of the enzymes used in the hydrolysis. |

1. A method for the treatment of lignocellulosic biomass comprising
(a) mixing lignocellulosic biomass with an ionic liquid for a sufficient time and temperature to swell the lignocellulosic biomass without dissolution of the lignocellulosic biomass in the ionic liquid; and (b) treating the swelled lignocellulosic biomass under mild alkaline treatment for about 1-60 minutes to separate the lignin from the cellulose and hemicellulose. |
