Fate of p-hydroxycinnamates and structural characteristics of residual hemicelluloses and lignin during alkaline-sulfite chemithermomechanical pretreatment of sugarcane bagasse
(BioMed Central, 2018)
Abstract
Background
Preparing multiple products from lignocellulosic biomass feedstock enhances the profit and sustainability of future biorefineries. Grasses are suitable ...
Limitation of cellulose accessibility and unproductive binding of cellulases by pretreated sugarcane bagasse lignin
(BioMed Central, 2017)
Abstract
Background
The effectiveness of the enzymatic hydrolysis of cellulose in plant cell wall is strongly influenced by the access of enzymes to cellulose, which is at ...
Side by side comparison of chemical compounds generated by aqueous pretreatments of maize stover, miscanthus and sugarcane bagasse
(SpringerNew York, 2014-12)
In order to examine the potential for coproduct generation, we have characterised chemical compounds released by a range of alkaline and acidic aqueous pretreatments as well as the effect of these pretreatments on the ...
Corrosion protection assessment of nanoparticulate pre-treated galvanized steel/paint systems subjected to accelerated tests
(Trade Science, 2016-07)
The development of environmentally friendly anticorrosive systems providing the same performance than those already existing has been the great challenge for researchers working in the surface treatment field. In this work ...
Ozonolysis applied to lignocellulosic biomass
(2018-01-01)
Lignocellulosic biomass produced by several agroindustrial processes has become the most important source of green carbon able to integrate the development of a mode of production based on the biorefinery concept. The ...
Avaliação do pré-tratamento acalino na hidrólise enzimática dos resíduos da palha de carnaúba
(Universidade Federal do Rio Grande do NorteBrasilUFRNEngenharia Química, 2017-10-26)
The carnauba (Copernicia prunifera) is a typical Brazilian northeast palm tree whose main economic activity is the extraction of wax. This activity presents a great generation of residue rich in cellulose, in which it has ...
Theoretical modeling and experimental validation of hydrodynamic cavitation reactor with a Venturi tube for sugarcane bagasse pretreatment
(2020-09-01)
A hydrodynamic cavitation reactor with a Venturi tube was modeled through a computational fluid dynamics approach in order to evaluate the influence of pressure ratio, diameter and length of the throat zone. A cavitation ...
High xylose yield from stem and external fraction of sugarcane biomass by diluted acid pretreatment
(2020-01-01)
Lignocellulosic materials are complex, recalcitrant, and difficult to release fermentable carbohydrates, such as xylose. Xylose is the feedstock for the development of products with high added value, such as ethanol, ...
