Thermal Degradation Kinetics of Sugarcane Bagasse and Soft Wood Cellulose
The properties of untreated sugar cane bagasse (SCB) and soft wood (SW) and their respective celluloses were investigated. The celluloses indicated improved crystallinity index values and decreased concentration of lignin and hemicellulose compared to their untreated counterparts. Three degradation models, Kissinger-Akahira-Sunose (KAS), Flynn-Wall-Ozawa (OFW), and Kissinger (KGR) methods were ...
متن کاملProspects of Cellulosic Ethanol from Sugarcane Bagasse
AGRICULTURAL residues such as grain straws and corn stover are abundant, readily available biomass feedstocks for the production of next generation biofuels, with collection and transport costs being a major component of their cost. Sugarcane bagasse is thus an especially attractive biomass feedstock in that it is an agricultural residue already present in large quantities at sugar and ethanol ...
متن کاملLimitation of cellulose accessibility and unproductive binding of cellulases by pretreated sugarcane bagasse lignin
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 least in part limited by the presence of lignin. Although physicochemical treatments preceding the enzymatic catalysis significantly overcome this recalcitrance, the residual lignin can still play a role in the process. Lignin is sugg...
متن کاملProduction of Single Cell Protein from Sugarcane Bagasse by Saccharomyces cerevisiae in Tray Bioreactor
In this study, solid state fermentation (SSF) was carried out to produce single cell protein (SCP) from sugarcane bagasse using Saccharomyces cerevisiae. The SSF experiment were performed in a tray bioreactor. The influence of several parameters including extraction buffer, initial moisture content of substrate, fermentation time, relative humidity in bioreactor, the bioreactor temperature and ...
متن کاملCellulosic films obtained from the treatment of sugarcane bagasse fibers with N-methylmorpholine-N-oxide (NMMO).
Ethanol/water organosolv pulping was used to obtain sugarcane bagasse pulp that was bleached with sodium chlorite. This bleached pulp was used to obtain cellulosic films that were further evaluated by Fourier transform infrared (FTIR) spectroscopy, thermogravimetric analysis (TGA), and scanning electron microscopy (SEM). A good film formation was observed when temperature of 74 degrees C and ba...
