The effect of using different acids to catalyze the prehydrolysis stage on the organosolv delignification of beech wood in two-stage process

, 2022
S.1479-1487In this study, beech wood was fractionated in lab scale rector by one-stage and two-stage processes. The two-stage processes of the prehydrolysis with no catalyst (only water) and catalyst (sulfuric, phosphoric, oxalic acids), and the ...

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.

Influence of Pre-Hydrolysis on the Chemical Composition of Prunus avium Cherry Seeds

Agronomy, 2022
During the industrial processing of sweet cherry fruits, the seeds are considered agricultural waste and must be disposed of, typically through burning. In this context, it is intended to contribute to the scientific development of the ecovalorization of

Comparison of monopersulfuric acid and sulfuric acid as prehydrolysis reagents for high-purity cellulose production from Japanese cedar via soda–anthraquinone (soda–AQ) cooking and totally chlorine-free (TCF) bleaching

Journal of Wood Science
Prehydrolysis/soda–anthraquinone (AQ) cooking has emerged as a promising strategy for the production of high-purity cellulose; however, optimization of the prehydrolysis stage is still required.

From Viscose to Lyocell‐Type Fibers: Chemical Recycling of Viscose and Modal Fibers Using the Ioncell Process

ChemSusChem, Volume 19, Issue 11, 15 June 2026.
Using the Ioncell process, the recycling of low DP textile waste via four case studies, white, blue, and black viscose and white modal fibers, was investigated. The most common man‐made cellulose fiber (MMCF) is viscose, a low DP material made of plant‐based cellulose, and it accounts for less than 6% of the total amount of textile fibers.

Removal of fermentation inhibitors from pre-hydrolysis liquor using polystyrene divinylbenzene resin

Biotechnology for Biofuels, 2020
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.

Efficient Separation and Purification of Oligosaccharides: A Systematic Review on Principles and Applications of Membrane Separation Technology

Food Bioengineering, Volume 5, Issue 2, Page 290-313, June 2026.
Membrane separation provides a green and scalable route for oligosaccharide purification. This review summarizes the complementary roles of microfiltration, ultrafiltration, nanofiltration, and reverse osmosis, with emphasis on membrane selection, optimization of operating conditions, fouling control, and integrated cascade design for improving purity,

The Hydrolysis of Cellulosic Materials in Ionic Liquids

BioResources, 2013
This study’s main objective was the dissolution of cellulose from biomass using ionic liquids to obtain saccharides by prehydrolysis. Raw materials were exposed to the ionic liquids (ILs) 1-ethyl-3-methylimidazolium acetate, 1-butyl-3-methylimidazolium ...

Hybrid Mesoporous Bifunctional Adsorbents of PbII and CdII Ions from Aqueous Solution at Ambient Temperature

ChemistryOpen, Volume 15, Issue 5, May 2026.
The bifunctionalization of the surface of mesoporous material SBA‐15 by thiol and amino as two organic functions via post‐ or successive grafting leads to obtaining a high performance and effective adsorbent for lead ion removal from aqueous solution. In contrast, there was a reduction in the cadmium ion removal rate. The simultaneous incorporation of –
