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 ... -
Hydrothermal treatments applied to agro- and forest- industrial waste to produce high added-value compounds
(North Carolina State University. Department of Wood and Paper Science, 2017-01-01)Agro- and forest-industrial wastes are abundant and low cost sources of carbohydrates and phenolic compounds, which can be converted into biofuels, biomaterials, and high added-value compounds by different pathways in small ... -
Removal of recalcitrant organic compounds from an industrial complex effluent by heterogeneous Fenton-type treatment
