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 ...
Fractionation of non-timber wood from Atlantic mixed forest into high-value lignocellulosic materials
(Taylor & Francis, 2020-03-10)
[EN] The forestry industry in the Basque Country has experienced an abandonment of small-sized forests in which native and introduced species tend to regrow if unattended; thus, requiring an intervention under which proper ...
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 ...
Fermentable sugars recovery from grape stalks for bioethanol production
(Elsevier, 2013-07-02)
[EN]Three different processes were investigated for the recovery of fermentable sugars from grape stalks:
autohydrolysis at 121 ºC before and after a pre-washing step and acid hydrolysis (2% H2SO4 w/w) after a
pre-washing ...
Corncob arabinoxylan for new materials
(Elsevier, 2014-02)
[EN]tCorncob agricultural waste was used as a source of arabinoxylan for preparation of films. Three ara-binoxylan samples were prepared: crude extract (CCAX), purified by a washing step, and purified bybleaching CCAX. ...
Extraction of flavonoid compounds from bark using sustainable deep eutectic solvents
(Elsevier, 2021-12)
[EN] The use of green solvents in extraction processes, especially for applications of lignocellulosic biomass, has been extensively studied over the last years. Among the range of different green solvents, deep eutectic ...
