Upgrading of wood pre-hydrolysis liquor for renewable barrier design : A techno-economic consideration

Cellulose, 2014
A techno-economic assessment of an upgrading procedure and outtake of a pre-hydrolysate in a presumed dissolving pulp mill was performed. Pre-hydrolysis of spruce wood chips in pilot scale produced input data for energy and mass balances and was ...

Combined Treatments Consisting of Calcium Hydroxide and Activate Carbon for Purification of Xylo-Oligosaccharides of Pre-Hydrolysis Liquor. [PDF]

Polymers (Basel), 2019
In this study, the effect of a combined treatment consisting of calcium hydroxide (CH) followed by activated carbon (AC) on the purification of hemicellulose in the pre-hydrolysis liquor (PHL) from pulping process has been evaluated. The results show that lignin and furfural of PHL are efficiently removed, and the lignin removal is achieved by forming ...

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 ...

Zero Excess Sludge Production in a Thermophilic MBR System: Performance and Energy Consumption Evaluation. [PDF]

Water Environ Res
A full‐scale thermophilic pure‐oxygen process coupled with ceramic ultrafiltration achieves over 85% volatile solids removal and extremely low biomass yields, enabling substantial sludge reduction. Despite higher energy demand, the recovery of soluble COD and robust long‐term performance make this approach a sustainable and regulation‐resilient sludge ...

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.
