A new approach to recycle oxalic acid during lignocellulose pretreatment for xylose production

Biotechnology for Biofuels, 2018
Background Dilute oxalic acid pretreatment has drawn much attention because it could selectively hydrolyse the hemicellulose fraction during lignocellulose pretreatment. However, there are few studies focusing on the recovery of oxalic acid.
