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 ...
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 ...
Multistage treatment of almonds waste biomass: characterization and assessment of the potential applications of raw material and products
(Elsevier, 2018-09-06)
Almond shells are waste biomass generated in agro-industrial activities, which represent a resource that can be further valorized upon treatment. The purpose of this work was to assess new value-added products obtained ...
Lignin oxidation and depolymerisation in ionic liquids
(RSC, 2015-09)
The depolymerisation of lignin directly in the black liquor was studied, comparing two ionic liquids as extracting solvents (butylimidazolium hydrogen sulphate and triethylammonium hydrogen sulphate), under oxidising ...
Study of the influence of reutilization ionic liquid on lignin extraction
(Elsevier, 2015-04-09)
The development of green techniques for biomass processing and fractionation is crucial from the point of view of sustainability and environmental protection. Lignin is the second most abundant bio-renewable material on ...
Willow lignin oxidation and depolymerization under low cost ionic liquid
(ACS, 2016-05-10)
Willow biomass was subjected to different pretreatmentconditions with triethylammonium hydrogen sulfate as solvent, andthe produced lignin solutions were treated by oxidation either homo-geneously using H2O2as oxidant or ...
