Optimization of the soda-ethanol delignification stage for a rice husk biorefinery
(Elsevier Science, 2017-03)
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 ...

Estudo da lignina residual da polpação soda na biorrefinaria do eucalipto para produção de etanol
(Universidade Estadual Paulista (Unesp), 2021-08-27)
Com preço crescente dos combustíveis associada ao consequente esgotamento das reservas não renováveis de combustíveis fósseis, são buscadas novas alternativas para suprir a demanda de energia e combustíveis no mundo. ...
Produção de bioetanol via hidrólise ácida de Eucalyptus urograndis utilizando os concei-tos de uma biorrefinaria: abordagem teórico experimental
(Universidade Estadual Paulista (Unesp), 2021-06-07)
Os combustíveis fósseis, além de serem recursos limitados na natureza, aumentam os níveis de dióxido de carbono e outros gases causadores do efeito estufa na atmosfera, neste aspecto os biocombustíveis surgem como uma ...
Synthesis and Characterization of ZnO Nanorod Films on PET for Photocatalytic Disinfection of Water
(Science & Technology Network, Inc.CA, 2015)
ZnO nanorods (ZnO NRs) were grown on ZnO seeded polyethylene tert-phtalate (PET) substrates obtained from
recycled soda bottles at low temperatures (90 °C) from Zn2+ precursors in alkaline aqueous solution. The ZnO
seeds ...
