A review on the efficient enzymatic regulation for lignin separation from pulping pre-hydrolysis liquor

Industrial Crops and Products
Pulping pre-hydrolysis liquor (PHL), a byproduct generated during the production of dissolving pulp, is rich in biomass resources, including hemicellulose, its degradation products, and lignin.

Formation and Identification of Lignin–Carbohydrate Complexes in Pre-hydrolysis Liquors

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 ...

Catalytic Conversion of Xylo-Oligomers to Furfural in Pulping Pre-Hydrolysis Liquor Using a Hydroxyl-Functionalized Covalent Organic Framework. [PDF]

Polymers (Basel)
With the rapid development of biorefinery technology, the efficient conversion of lignocellulose into high-value platform chemicals is of great significance for enhancing the value of renewable carbon resources. In this study, a hydroxyl-functionalized covalent organic framework (COF), TAPB-DHPA, was synthesized via an in situ method and innovatively ...

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.

Structural characterization of soluble lignin in the pre-hydrolysis liquor of bamboo-willow dissolving pulp [PDF]

BioResources, 2019
The soluble lignin present in the pre-hydrolysis liquor (PHL) is detrimental for value-added utilization of the PHL from production of kraft-based dissolving pulp. In this paper, the soluble lignin was separated from PHL by activated carbon adsorption and subsequent desorption with methanol.

Effect of Coagulating Agents on Lignin and Oligosaccharide Contents in Pre-Hydrolysis Liquor Obtained in the Production of Dissolving Pulp from Poplar Residual Slabs

BioResources, 2015
Pre-hydrolysis is an important step in the poplar residual slab dissolving pulp production process, as it aids in removing as much hemicellulose as possible from the cellulose fibers.

Synthesizing Magnetic Support for Laccase Immobilization for the Purification of Pre-hydrolysis Liquor

BioResources, 2018
Laccase immobilization is a promising method for the purification of pre-hydrolysis liquor (PHL) for large-scale applications based on recyclability and reusability. In this work, magnetic supports made of Fe3O4/SiO2 were synthesized by a sol-gel method and coated with silica.
