Formation and Identification of Lignin-Carbohydrate Complexes in Pre-hydrolysis Liquors. [PDF]
Biomacromolecules, 2023 The lignin-carbohydrate complexes (LCCs) typically present in the liquors produced in the pre-hydrolysis of biomass cause severe difficulties in downstream fractionation. To address this issue, a series of LCC samples were accessed from solutions obtained from the pre-hydrolysis of extractive-free pine wood meal (H-LCC) and compared with LCC obtained ...

Dissolving Kraft Pulp Production and Xylooligosaccharide Coproduction: Effect of Pre-Hydrolysis Conditions. [PDF]
ACS Omega, 2023 Due to cotton's declining sustainability, more lignocellulosic materials are being used to produce dissolving pulp for textile applications. Pre-hydrolysis kraft is one of the main processes used to produce this material. Pre-hydrolysis under conventional conditions removes most of the hemicelluloses, but the majority end up as xylose and furfural ...

Removal of fermentation inhibitors from pre-hydrolysis liquor using polystyrene divinylbenzene resin. [PDF]
Biotechnol Biofuels, 2020 Abstract Background The presence of soluble lignin, furfural and hydroxymethylfurfural (HMF) in industrial pre-hydrolysis liquor (PHL) from the pulping process can inhibit its bioconversion into bioethanol and other biochemicals. Although various technologies have been developed to remove these

A Novel and Effective Recyclable BiOCl/BiOBr Photocatalysis for Lignin Removal from Pre-Hydrolysis Liquor. [PDF]
Nanomaterials (Basel), 2021 The presence of lignin hampers the utilization of hemicelluloses in the pre-hydrolysis liquor (PHL) from the kraft-based dissolving pulp production process. In this paper, a novel process for removing lignin from PHL was proposed by effectively recycling catalysts of BiOCl/BiOBr.

Effect of pre-hydrolysis on floc structure [PDF]
Journal of Environmental Management, 2004 Morphological changes in flocs were elucidated by small-angle light scattering, free settling tests and microscopic observation to determine the effects of pre-hydrolysis (alkaline treatment and ultrasonication) on two sludges--primary raw sludge from the Malabar Sewage Treatment Plant, Sydney (sludge M) and biological sludge collected at the nitrogen ...

Enhancing Liquefaction Efficiency: Exploring the Impact of Pre-Hydrolysis on Hazelnut Shell (Corylus avellana L.). [PDF]
Materials (Basel)Hazelnut shells (HS), scientifically known as Corylus avellana L. shells, are waste produced by companies that process nuts. The main objective of this study was to find an efficient way to maximize the chemical potential of HS by solubilizing the hemicelluloses, which could then be used to recover sugars and, at the same time, increase the lignin ...

Enhanced biochemical process for purifying xylo-oligosaccharides from pre-hydrolysis liquor [PDF]
, 2020 Abstract Background Xylo-oligosaccharides (XOS) are promising biomass-derived chemicals that can be widely used in preparing medicines, food additives, and industrial chemicals. The pre-hydrolysis liquor (PHL) produced in the kraft-based dissolving pulp production process is rich in hemicelluloses and especially in XOS/xylan.
