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 ...
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 ...
Estudio de aplicación de quelantes en la obtención de pulpas Kraft blanqueadas TCF.
(Universidad Nacional de Misiones. Facultad de Ciencias Exactas, Químicas y Naturales. Secretaría de Investigación y Posgrado. Maestría en Ciencias de la Madera, Celulosa y Papel, 2004-07-10)
Es sabido que el pulpado kraft ocupa un lugar preponderante en Argentina y en el mundo. Debido al gran desarrollo del mismo, podría suponerse que queda poco espacio para mejorar el proceso. Sin embargo, las presiones ...
Techno‐economic assessment of carboxylic acids, furfural, and pellet production in a pine sawdust biorefinery
(John Wiley & Sons, Ltd, 2018-08-19)
Pine sawdust is an important lignocellulosic waste from the primary industrialization of wood, and its valorization using the biorefinery concept could add new value chains to the forest industry. Compared with large‐scale ...
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
(Wiley, 2016-12-30)
Because of their chemical complexity, industrial chemi-mechanical pulping effluents are evaporated and burned, in spite of the high associated cost involved in these processes. The aim of this study was to remove recalcitrant ...
Studies on lignin extraction from rice husk by a soda-ethanol treatment : kinetics, separation, and characterization of products
(Elsevier, 2018-01-01)
The delignification kinetics of lignocellulosic waste is an important tool for the study of the technical-economic viability of biorefinery processes. The aim of this work was to study the kinetic of lignin extraction by ...
Alternatives of small-scale biorefineries for the integrated production of xylitol from sugarcane bagasse
(Scrivener Publishing LLC, 2018-03-01)
Small-scale biorefinery from sugarcane bagasse offers new possibilities to the sugar and ethanol industries. The aim of this study was to evaluate the feasibility of a small-scale biorefinery for the production of xylitol ...
Dissolving pulps by oxidation of the cellulosic fraction of lignocellulosic waste
(Editura Acad Romane, 2017-12-01)
Cellulosic fractions of Eucalyptus sp. sawdust pulp and of sugarcane bagasse pulp, which had been subjected to hydrothermal and alkaline treatments, were purified by oxidative means (oxygen and ozone, followed by an alkaline ...
Kinetic modeling of a heterogeneous Fenton‐type oxidative treatment of complex industrial efuent
(Springer Nature, 2018-09-17)
This work proposes a kinetic model for the reactions involved in the heterogeneous copper-based Fenton-type oxidation of mixed recalcitrant compounds in a real industrial effluent from the alkaline sulfite treatment of ...
