Kinetics of autocatalytic acid hydrolysis of cellulose with crystalline and amorphous fractions
(SPRINGER, 2010)
The acid hydrolysis of cellulose with crystalline and amorphous fractions is analyzed on the basis of autocatalytic model with a positive feedback of acid production from the degraded biopolymer. In the condition of low ...
Improved pretreatments applied to the sugarcane bagasse and release of lignin and hemicellulose from the cellulose-enriched fractions by sulfuric acid hydrolysis
(2014)
BACKGROUND A number of pretreatments have been reported in the literature aiming to improve yields with increases in degree of digestibility of the cellulose-enriched fractions, in reducing the process time recalcitrance ...
Fractionation of cellulose acetate for the investigation of molecular weight influences on the morphology of membranes
(Elsevier Science BvAmsterdamHolanda, 2003)
Pseudo-Lignin Content Decreased with Hemicellulose and Lignin Removal, Improving Cellulose Accessibility, and Enzymatic Digestibility
(2020-01-01)
The sugarcane bagasse is a heterogeneous material and needs a pretreatment to breakdown its complex structure to make cellulose accessible to enzyme action. This study aimed to evaluate pseudo-lignin formation, enzymatic ...
Two-stage alkaline and acid pretreatment applied to sugarcane bagasse to enrich the cellulosic fraction and improve enzymatic digestibility
(2020-01-01)
Sugarcane bagasse (SB) is made up of cellulose (32-43%), hemicellulose (19-34%) and lignin (14-30%). Due to high recalcitrant nature of SB, pretreatment is required to deconstruct its structure and enrich the cellulosic ...
Effects of pretreatment applied to sugarcane bagasse on composition and morphology of cellulosic fractions
(2019-07-01)
Due to the growing demand for renewable energy, the energy based on biomass plays an important role in energy policies of countries all over the world. Seven different pretreatments were performed on SCB to obtain yields, ...
The Role of Heterogeneous Catalysts in Converting Cellulose to Platform Chemicals
(2020-01-01)
In times of rethinking production processes and consumption habits to minimize the effects of global warming, it is crucial to find alternatives that lead to replacing fossil fuels by renewable materials. The development ...
Quantitative microscopy characterization of hydrous niobium phosphate into bleached cellulose
(Pergamon-Elsevier B.V. Ltd, 2010-07-01)
In this research the spatial distribution characterization of niobium phosphate into bleached cellulose was carried out combining processing and images analysis obtained by SEM and statistical methodologies. The objective ...
