Fractionation of sugarcane bagasse by hydrothermal treatment
Bioresource Technology, 2003Hydrothermal treatment of sugarcane bagasse was conducted using a semi-batch reactor to develop a new biomass fractionation method that has low impact in the environment. A continuously increasing temperature was used in this treatment. It was found that hemicellulose and lignin could be mainly extracted as a water-soluble fraction at 200-230 degrees C,

Vacuum pyrolysis of sugarcane bagasse
Journal of Analytical and Applied Pyrolysis, 2002Abstract The objective of this study was to provide background data on sugarcane bagasse vacuum pyrolysis. Product yields and properties were investigated. Vacuum pyrolysis tests were performed at bench and pilot plant scales. The bagasse finest particles with a diameter smaller than 450 μm were removed in order to overcome difficulties caused by ...

Characterization of sugarcane bagasse powders
Powder Technology, 2011Abstract 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 ...

The influence of supermasscolloider on the morphology of sugarcane bagasse and bagasse cellulose
Fibers and Polymers, 2016Sugarcane bagasse (SB) was subjected to mechanical and chemical treatments in order to investigate the influence of both treatments on the morphology of cellulose extracted from SB. Samples treated with supermasscolloider (SMC) showed a slight increase in the cellulose content and a highest content after chemical treatment.

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.

Comparative hydrolysis and fermentation of sugarcane and agave bagasse
Bioresource Technology, 2009Sugarcane and agave bagasse samples were hydrolyzed with either mineral acids (HCl), commercial glucanases or a combined treatment consisting of alkaline delignification followed by enzymatic hydrolysis. Acid hydrolysis of sugar cane bagasse yielded a higher level of reducing sugars (37.21% for depithed bagasse and 35.37% for pith bagasse), when ...

Succinoylation of sugarcane bagasse under ultrasound irradiation
Bioresource Technology, 2008The 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,

Lime Pretreatment of Sugarcane Bagasse for Bioethanol Production
Applied Biochemistry and Biotechnology, 2008The 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.
