Cellulose Membranes in the Treatment of Spent Deep Eutectic Solvent Used in the Recovery of Lignin from Lignocellulosic Biomass
(MDPI, 2022-01-13)
Ultrafiltration was employed in the purification of spent Deep Eutectic Solvent (DES, a mixture of choline chloride and lactic acid, 1:10, respectively) used in the extraction of lignin from lignocellulosic biomass. The ...
Towards Sawdust Products Ecosystem? Three Utilization Process Cases From Finland
(Open Bioeconomy Week, 2022-05-19)
There is a huge demand to utilize renewal side flows of different production processes to substitute existing fossil-based products or to develop and produce totally new products to the market. One underutilized side product ...
Effect of Low Concentrations of Lithium Chloride Additive on Cellulose-Rich Ultrafiltration Membrane Performance
(MDPI, 2023-02-05)
Various water treatment processes make extensive use of porous polymeric membranes. A key objective in membrane fabrication is to improve membrane selectivity without sacrificing other properties such as permeability. ...
Wood-Based Cellulose-Rich Ultrafiltration Membranes: Alkaline Coagulation Bath Introduction and Investigation of Its Effect over Membranes’ Performance
(MDPI, 2022-05-31)
In this study, wood-based cellulose-rich membranes were produced with a novel approach to casting procedure. Flat-sheet membranes were prepared from birch biomass pretreated with deep eutectic solvent and dissolved in ionic ...
Long‑term stability of cellulose membranes in spent deep eutectic solvent used in the recovery of lignin from lignocellulosic biomass
(Springer Nature, 2024-02-02)
Deep eutectic solvents (DESs) are a novel class of solvents that can be used to fractionate biomass compounds. However, their sustainability depends strongly on their recyclability. In previous research, it was seen that ...
