Effect of Boric Acid Addition on the Prehydrolysis of Whangee

open access: yesBioResources, 2016
Prehydrolysis is an important step in the kraft-based dissolving process for pulp production, as it helps remove as much hemicellulose as possible from cellulose fibers before the material is subjected to the main delignification operation, i.e., pulping.

Microwave-assisted recovery of monomeric sugars from an acidic steam treated wood hydrolysate [PDF]

open access: yesHeliyon, 2018
Fractionation of components from bio-refinery wastes streams is complicated by the presence of both oligomer and lignin fractions. Microwave-assisted acid hydrolysis was used in this study to convert oligomer sugars in an industrial prehydrolysis liquor (

Continuous Enzymatic Prehydrolysis Treatment of High-Fat Wastewater

open access: yesFood Technology and Biotechnology, 2013
A lipolytic fermented solid was produced by solid-state fermentation of Rhizopus microsporus CPQBA 312-07 DRM on a mixture of sugarcane bagasse and sunflower seed meal and used, in a packed-bed bioreactor, to pretreat a high-fat wastewater from a meat ...

PRODUCTION OF DISSOLVING GRADE PULP FROM ALFA [PDF]

open access: yesBioResources, 2010
Alfa, also known as Stipa tenacissimaI or “halfa”, is grown in North Africa and south Spain. Due to its short fiber length, paper made from alfa pulp retains bulk and takes block letters well.

Sugar cane bagasse prehydrolysis using hot water [PDF]

open access: yesBrazilian Journal of Chemical Engineering, 2012
Results are presented on the hot water prehydrolysis of sugar cane bagasse for obtaining ethanol by fermentation. The experimental study consisted of the determination of the effect of temperature and time of prehydrolysis on the extraction of hemicelluloses, with the objective of selecting the best operating conditions that lead to increased yield of ...

Understanding the effect of severity factor of prehydrolysis on dissolving pulp production using prehydrolysis kraft pulping and elemental chlorine-free bleaching sequence [PDF]

open access: yesBioResources, 2020
Prehydrolysis kraft pulping is an effective approach to produce dissolving pulp, which can be used for viscose application. The prehydrolysis process using hot liquid water could remove hemicellulose and loosen the compact cell wall, thus facilitating subsequent pulping and bleaching processes.
