LiBr-Formic Acid Enables Lignocellulosic Biomass Fractionation within 10  Minutes.

ABSTRACT: Efficient biomass fractionation is essential for enhancing resource efficiency in the circular bioeconomy. However, achieving rapid, effective fractionation while minimizing the use of non-recyclable chemicals remains challenging and also often yields low component purity. To circumvent these issues, an LiBr-assisted formic acid (LB-FA) system is developed that enables biomass fractionation within 10 min without auxiliary technologies. It is found that adding LiBr facilitates biomass swelling, improving liquid penetration and component-removal efficiency. Moreover, LiBr promotes the dissociation of formic acid, enhancing the removal of hemicellulose and lignin. The LB-FA system removed 96.0% of lignin and 99.6% of hemicellulose from poplar wood, yielding cellulose with 97.2% purity and lig
