Fractionation of Wood Biomass With Thiolactic Acid and Choline Chloride-Based Solvent Into White Lignin for Sustainable Cooling Applications. [PDF]

ChemSusChem
A novel and highly efficient wood biomass fractionation method was developed to produce white lignin, exhibiting the brightest color reported to date. The process yielded white lignin with high yield, excellent visible light reflectance, and elevated infrared emissivity, highlighting its potential as an active material for passive radiative cooling ...

One-Step Extreme Delignification to Simultaneously Produce High-Purity Cellulose and Phenolated Lignin. [PDF]

ChemSusChem
An extreme delignification strategy using a formic acid–phenol–water system enables the simultaneous production of high‐brightness cellulose fibers and highly reactive phenolic lignin from various biomass sources, providing a sustainable pathway for high‐value utilization of lignocellulosic biomass.

Electrochemical Characteristics of Lignin in CTMP for Paper Battery Electrodes. [PDF]

ChemSusChem
Lignin naturally present in papers made of unbleached mechanical pulps is electrochemically active. Here, softwood chemi‐thermomechanical pulp (CTMP) is studied as an active cathode material for application in paper batteries. Proof‐of‐concept measurements are shown, and it is found that softwood CTMP fines exhibit competing oxidative electrochemical ...

Ethanol Production from Hydrolyzed Kraft Pulp by Mono- and Co-Cultures of Yeasts: The Challenge of C6 and C5 Sugars Consumption

Energies, 2020
Second-generation bioethanol production’s main bottleneck is the need for a costly and technically difficult pretreatment due to the recalcitrance of lignocellulosic biomass (LCB).

Microfibrillated lignocellulose (MFLC) and nanopaper films from unbleached kraft softwood pulp [PDF]

Cellulose, 2019
AbstractMicrofibrillated cellulose (MFC) is an important industrial nanocellulose product and material component. New MFC grades can widen the materials property range and improve product tailoring. Microfibrillated lignocellulose (MFLC) is investigated, with the hypothesis that there is an optimum in lignin content of unbleached wood pulp fibre with ...

Bleached kraft pulp production from Pinus tecunumanii (Eguiluz e Perry) Produção de polpa kraft branqueada de Pinus tecunumanii (Eguiluz e Perry)

Revista Árvore, 2005
The use of 12-year-old Pinus tecunumanii (Eguiluz e Perry) grown in Colombia was evaluated for bleached kraft pulp production. Kraft pulps of kappa number 30 ± 1 were produced, and oxygen delignified and bleached to 90% ISO with ECF processes.

Stellera chamaejasme Roots as Raw Material for Pulp Production

BioResources, 2014
Cellulosic pulps were prepared from Stellera chamaejasme roots using soda, soda-anthraquinone (soda-AQ), and kraft pulping processes. S. chamaejasme is composed of 73.5% holocellulose, 39.7% α-cellulose, and 17.6% lignin, similar to wheat straw and other
