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, ...
Effect of different hemicelluloses characteristics on film forming properties
(Elsevier, 2013)
Hemicelluloses are known to have good gas barrier properties makes them of interest to film applications.
Corn cob, cotton waste, olive, apple tree pruning, pepper and chilli wastes were used as hemicelluloses
sources ...
Effect of alkaline and autohydrolysis processes on the purity of obtained hemicelluloses from corn stalks
(Elsevier, 2012)
[EN]A study of the potential of autohydrolysis and alkaline extraction processes from corn stalks was performed
for high purity hemicellulose extraction. The influence of process parameters on the purity of
obtained ...
Direct lignin depolymerization process from sulfur-free black liquors
(Elsevier, 2019-09-03)
Agricultural residues (olive tree pruning and almond shell) were subjected to different delignification treatments (organosolv and soda) and the obtained liquors were treated in a high-pressure reactor at 300 °C for 80 min ...
