Lignin-first integrated steam explosion process for green wood adhesive application

Résumé

Steam explosion (SE) is one of the most advanced pretreatment processes currently used for the production of biofuel from lignocellulose. However, steam explosion lignin is generally recovered as a secondary impure co-product, mainly used for energy production. In this work, beech wood sawdust was first exploded at 180°C or 200°C during 5 min after water or dilute acid impregnation. The recovery of lignin from exploded wood was studied using an alkali process at 80°C or an ethanol-organosolv process at 200°C. The impact of the SE parameters and of the delignification step on the lignin structure was examined by size exclusion and ionic chromatography (SEC), 31 P and HSQC NMR spectroscopies.
