Characterization of sugarcane bagasse powders

Powder Technology, 2011
Abstract Sugarcane bagasse is a promising renewable lignocellulosic feedstock. Hence, proper characterization of bagasse powders is important for the development of novel technologies based on this resource. In this work, bagasse powders are prepared by sieve fractionation followed by cutting milling and rotor milling (which acts by impact, shear ...

Sugarcane Bagasse Pulps

2009
Organosolv (ethanol/water and acetosolv) pulps were treated with Bacillus pumilus xylanase for 4,8, and 12 h and compared with commercial Cartazyme HS xylanase-treated pulps. Treatment of ethanol/water pulps with B. pumilus xylanase increased viscosity by 40% in 8 h of treatment compared with pulps treated without enzyme.

Inhomogeneities in the Chemical Structure of Sugarcane Bagasse Lignin

Journal of Agricultural and Food Chemistry, 2003
Sequential treatments of dewaxed bagasse with distilled water, 0.5 M NaOH, 0.5, 1.0, 1.5, 2.0, and 3.0% H(2)O(2) at pH 11.5, and 2 M NaOH at 55 degrees C for 2 h solubilized 2.8, 52.5, 14.9, 3.3, 5.5, 5.0, 2.8, and 2.2% of the original lignin, respectively.

Succinoylation of sugarcane bagasse under ultrasound irradiation

Bioresource Technology, 2008
The chemical modification of sugarcane bagasse with succinic anhydride using pyridine as solvent after ultrasound irradiation was studied. The optimized parameters included ultrasound irradiating time 0-50 min, reaction time 30-120 min, succinic anhydride concentration by the ratio of dried sugarcane bagasse to succinic anhydride from 1:0.25 to 1:1.50,

Ontology Modelling for Valorisation of Sugarcane Bagasse

2023
Sugarcane bagasse (SCB) is an agro-industrial residue extracted during sugar processing. Sugar mills use basic process technologies for bagasse valorisation. Residues are often disposed improperly or burned inefficiently by thermal boilers causing environmental pollution. Biorefining bagasse as substrate for bio-based chemical production is superior to

Lime Pretreatment of Sugarcane Bagasse for Bioethanol Production

Applied Biochemistry and Biotechnology, 2008
The pretreatment of sugarcane bagasse with lime (calcium hydroxide) is evaluated. The effect of lime pretreatment on digestibility was studied through analyses using central composite design (response surface), considering pretreatment time, temperature, and lime loading as factors.

Kinetic studies of thermal decomposition of sugarcane bagasse and cassava bagasse

Journal of Thermal Analysis and Calorimetry, 2016
The thermal decomposition of sugarcane bagasse and cassava bagasse was investigated by the use of the non-isothermal thermogravimetric technique. The experiments were performed with the following heating rates: 5, 10, 15, 20 and 30 °C min−1. The kinetic parameters of thermal decomposition were estimated by the Flynn–Wall–Ozawa and the Kissinger methods.

Etherification of hemicelluloses from sugarcane bagasse

Journal of Applied Polymer Science, 2007
AbstractConditions for the preparation of etherified hemicelluloses from sugarcane bagasse with 2, 3‐epoxypropyltrimethylammonium chloride (ETA) using sodium hydroxide as a catalyst in aqueous solution were studied comparatively. The extent of the etherification was measured by yield percentage and degree of substitution.

Adsorption of Direct Red 80 Dye from Solution by Sugarcane Bagasse and Modified Sugarcane Bagasse as Adsorbents

Materials Science Forum, 2016
The sugarcane bagasse and modified sugarcane bagasse with 1.0 M H2SO4 were used as adsorbents for removal of the direct red 80 in batch adsorption process. The effect on the initial concentration of the direct red 80, at 215.8 - 1028.9 mg/L, was thoroughly investigated in batch adsorption system.

Characterization of sugarcane bagasse by autofluorescence microscopy

Cellulose, 2013
The spatial distribution of chemical compounds in sugarcane bagasse is an important issue in its use as a raw material for second generation ethanol production from cellulose hydrolysis. Lignocellulosic materials including whole bagasse, fiber, pith, and respective samples obtained after chemical bleaching were investigated using confocal fluorescence ...
