The complete conversion of bleached kraft pulp into dissolving pulp and two xylo-oligosaccharides through a deep eutectic solvent-assisted biorefinery

Abstract

Refining Kraft pulp into dissolving pulp preparation methods are generally has been limited by aggressive chemical input and overlook of xylan component valorization. This work demonstrated an integrated process of...

Efficient fractionation of pure hemicellulose with high DP from bleached hardwood pulp using LiBr·3H2O and co-production of dissolving pulp

“…51 Although the hemicellulose in hardwoods is acetylated hemicellulose, most of the acetyl groups are removed during the production of BHKP (via kraft cooking and bleaching). 52 Therefore, the regenerated hemicellulose has no absorption peak at 1730 cm −1 . Moreover, the 1 H-NMR spectra (Fig.…”
