Integration of a kraft pulping mill into a forest biorefinery: pre-extraction of hemicellulose by steam explosion versus steam treatment.
TLDR
Although both pre-treatments increased delignification during pulping, steam explosion was significantly better than other options, and similar reductions in paper strength were found regardless of the type of treatment and conditions assayed, which is attributed to the increase of curled and kinked fibers.About:

Journal ArticleDOI
Sequential fractionation of the lignocellulosic components in hardwood based on steam explosion and hydrotropic extraction
TL;DR: This work shows the potential of sequential STEX and HEX to fractionate and isolate cellulose, hemicellulose, and a sulfur-free lignin in separate product streams, in an efficient, sustainable, and scalable process.
Impact of hemicellulose pre-extraction for bioconversion on birch kraft pulp properties
TL;DR: It is demonstrated that white liquor can be utilized to extract xylan from birch wood chips prior to Kraft cooking without decreasing the pulp yield and paper strength properties, while simultaneously impregnating cooking alkali into the wood chips.

Second Generation Bioethanol Production: On the Use of Pulp and Paper Industry Wastes as Feedstock
TL;DR: In this paper, a review of the literature supporting the feasibility of producing ethanol from Kraft pulp, spent sulfite liquor, and pulp and paper sludge is presented and discussed the practical attempt of biorefineries implementation in pulp and Paper mills for bioethanol production.
Journal ArticleDOI
Efficient extraction of bagasse hemicelluloses and characterization of solid remainder.
TL;DR: To reduce the degradation of cellulose and obtain high molecular weight of hemicellulose from the extracts, pH pre-corrected hot water pretreatment was developed by employing sodium hydroxide (3.9mol/L).
Journal ArticleDOI
Extraction of hemicellulose by hot water to reduce adsorbable organic halogen formation in chlorine dioxide bleaching of bagasse pulp
TL;DR: In this paper, a pH pre-corrected hot water pretreatment was developed to study the influence of the content of hemicellulose on the absorbable organic halogen (AOX) formation in chlorine dioxide bleaching.

Substrate pretreatment: the key to effective enzymatic hydrolysis of lignocellulosics?
TL;DR: Focusing particularly on steam pretreatment, this review examines the influence that pretreatment conditions have on substrate characteristics such as lignin and hemicellulose content, crystallinity, degree of polymerization and specific surface, and the resulting implications for effective hydrolysis by cellulases.

Lignin depolymerization/repolymerization and its critical role for delignification of aspen wood by steam explosion.
TL;DR: Addition of a reactive phenol, 2-naphthol, was shown to inhibit the repolymerization reaction strongly, resulting in a highly improved delignification by subsequent solvent extraction and an extracted lignin of uniform structure.
