Optimization of the pyrolysis process for the production of a biomass derived reducing agent and hydrogen-rich gases
(2014-06-30)
[EN] This thesis is devoted to the optimization of the biomass pyrolysis process for the simultaneous production of bioreducing agents and high value gases. The thesis is part of the existing collaborative research work ...
Lignin extraction, purification and depolymerization study
(Servicio Editorial de la Universidad del País Vasco/Euskal Herriko Unibertsitatearen Argitalpen Zerbitzua, 2014-05-12)
Petroleum reverses are depleting, fuel prices are increasing and the push of theenvironmental policies such as Kioto protocol are forcing the search for new biofuels,biomaterials and biochemicals. Lignocellulosic biomass ...
Advanced Reaction Systems for Hydrogen Production
(Servicio Editorial de la Universidad del País Vasco/Euskal Herriko Unibertsitatearen Argitalpen Zerbitzua, 2014-03-07)
[EN] This PhD work started in March 2010 with the support of the University of the Basque Country (UPV/EHU) under the program named “Formación de Personal Investigador” at the Chemical and Environmental Engineering Department ...
Supramolecular Structure and Renaturation of a (1→3)-β-D-Glucan Compared with Curdlan and Scleroglucan
(MDPI, 2014-09-22)
A (1→3)-β-D-Glucan produced by Lactobacillus suebicus CUPV221 strain was
investigated by tapping mode atomic force microscopy (TM-AFM), to compare its
supramolecular structure and conformation with two commercial ...
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 ...
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, ...
Flexible polyurethane foams based on 100% renewably sourced polyols
(Elsevier, 2014-10-5)
Since polyol is one of the major components in polyurethane foam synthesis, introducing renewably
sourced polyols in the foam formulation leads to materials with high renewable carbon content. A series of
flexible ...
Generation of nanocomposites based on (PMMA-b-PCL)-grafted Fe2O3 nanoparticles and PS-b-PCL block copolymer
(Elsevier, 2014-07-14)
The aim of this work is to obtain a good dispersion of Fe2O3 magnetic nanoparticles into a PS-b-PCL diblock copolymer. For this purpose nanoparticles have been modified in their surface by grafting a PMMA-b-PCL block ...
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. ...
