Preparation and characterization of composites based on poly(lactic acid)/poly(methyl methacrylate) matrix and sisal fiber bundles: The effect of annealing process
(Sage, 2020-06-12)
The interest on poly(lactic acid) (PLA)/poly(methyl methacrylate) (PMMA) blends has increased during the last years due to their promising properties. The novelty of the current work focuses on the preparation and ...
Simultaneous catalytic de-polymerization and hydrodeoxygenation of lignin in water/formic acid media with Rh/Al2O3, Ru/Al2O3 and Pd/Al2O3 as bifunctional catalysts
(Elsevier, 2015-04-28)
[EN] The catalytic solvolysis of 3 lignins of different sources in a formic acid/water media using bifunctional Ru/Al2O3, Rh/Al2O3, Pd/Al2O3 catalysts was explored in a batch set-up at different temperatures and reaction ...
Properties of flexible polyurethane foams containing isocyanate functionalized kraft lignin
(Elsevier, 2017-02-20)
A commercial kraft lignin (k-lignin) was successfully functionalized by means of the reaction of an isocyanate group from isophorone diisocyanate (IPDI) with hydroxyl groups present in lignin (k-IPDI), for their further ...
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 ...
Study of a renewable capping agent addition in lignin base catalysed depolymerisation process
(Elsevier, 2020-07-13)
The aim of this work was to study the influence of a renewable capping agent (CA) in the production of monomeric compounds from the depolymerization of an organosolv lignin (Pinus radiata) by a base catalyzed depolymerization ...
Solvent and catalyst effect in the formic acid aided lignin-to-liquids
(Elsevier, 2018-09-13)
[EN] The effect of the type of solvent, ethanol or water, and a Ru/C catalyst were studied in the formic acid aided lignin conversion. The best results were obtained in the presence of the Ru/C catalyst and using ethanol ...

Biocomposites Based on Poly(Lactic Acid) Matrix and Reinforced with Lignocellulosic Fibers: The Effect of Fiber Type and Matrix Modification
(Taylor & Francis, 2020-02-14)
in composite materials, two or more different components are combined to produce a new material with different characteristics from the individual components. In recent years, due to environmental concerns, the development ...
