The emergence of nanocellulose aerogels in CO2 adsorption
(Elsevier, 2024-02)
Mitigating the effect of climate change toward a sustainable development is one of the main challenges of our century. The emission of greenhouse gases, especially carbon dioxide (CO2), is a leading cause of the global ...
Sonochemical oxidation of technical lignin to obtain nanoparticles with enhanced functionality
(RSC, 2023-11)
Kraft lignin (KL) was treated by employing mild oxidation conditions enhanced by ultrasound irradiation (US) for obtaining more functionalized particles, avoiding the undesired side reactions of degradation and depolymerization. ...
Integral Valorization of Posidonia oceanica Balls: An Abundant and Potential Biomass
(MDPI, 2024-01-04)
Posidonia oceanica balls (POB), a kind of seagrass, are a significant environmental issue since they are annually discharged onto beaches. Their current usefulness limits interest in their management and enhances the ...
Base catalysed depolymerization of lignin: Influence of organosolv lignin nature
(2014-07)
Three different lignins obtained from olive tree pruning by organosolv processes
(acetosolv, formosolv and acetosolv/formosolv) were depolymerized by alkaline hydrolysis in a batch reactor to produce high value added ...
Economic analysis of a biorefinery process for catechol production from lignin
(Elsevier, 2018-10)
Recently, the valorization of the lignin fraction in the biorefinery scheme is getting more and more attention as the use of this component for the production of bio-based chemicals is crucial for the success of the integral ...
Depolymerization of different organosolv lignins in supercritical methanol, ethanol and acetone to produce phenolic monomers
(ACS, 2015-12-18)
Olive tree pruning was delignified by organosolv processes (acetosolv, formosolv and acetosolv/formosolv) to extract different lignins. The obtained lignins (acetosolv lignin (AL), formosolv lignin (FL) and acetosolv/formosolv ...
Effect of the photocatalytic activity of TiO2 on lignin depolymerization
(Elsevier, 2013-05)
Lignin is a good candidate for photocatalytic cracking due to the presence of hydroxyl groups. The photocatalytic cracking reaction involves TiO2 as heterogeneous catalyst.
In the present work lignin obtained by two ...
Characterisation of bark of six species from mixed Atlantic forest
(Elsevier, 2019-10)
[EN] Bark is one of the most available by-product derived from the wood-base industry because of the total volume of the tree that comprised. This study aimed at evaluating the chemical composition of barks of six typical ...
Effect of different organosolv treatments on the structure and properties of olive tree pruning lignin
(Elsevier, 2014-05-25)
Different organosolv processes (acetosolv, formosolv and acetosolv/formosolv) were applied to extract lignin from olive tree pruning. Obtained lignins were characterized by several methods to determine their composition, ...
