Hemicellulose extraction from slash pine sawdust by steam explosion with sulfuric acid
(Elsevier, 2017-12-01)
One of the main obstacles to the development of advanced forest biorefineries is the optimal fractionation of the plant biomass. The aim of this work was to design a two-stage process for the fractionation of slash pine ...
Optimization of the soda-ethanol delignification stage for a rice husk biorefinery
(Elsevier, 2017-03-01)
The aim of this work was to optimize the delignification of the hemicelluloses-free fraction of rice husk to obtain fractions of lignin, cellulose, and inorganics, which could be valorized in the context of the rice husk ...
Advances on the synthesis of porous TiO2 coatings by anodic spark oxidation : photocatalytic reduction of Cr(VI)
(Elsevier, 2017-04-15)
Porous TiO2 coatings were obtained by anodic oxidation in spark discharge conditions, varying the range of current density (200–3000 A m−2) and the electrolyte concentration (H2SO4; 1 and 4 M). The samples were characterized ...
