Optimization of Process Conditions for Subcritical Water Hydrolysis of Sugarcane Bagasse
Optimization of operation conditions (temperature, time, solvent: solid proportion) of subcritical water hydrolysis (SWH) is needed so that it can be considered an effective process for second generation bioethanol manufacturing. The objective of this study was to optimize operation conditions using a semi-batch SWH system equipped with a 50 mL reaction vessel. Initially, the process was carrie...
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 کاملComparison between Wet Oxidation and Steam Explosion as Pretreatment Methods for Enzymatic Hydrolysis of Sugarcane Bagasse
Alkaline wet oxidation and steam explosion pretreatments of sugarcane bagasse were compared with regard to biomass fractionation, formation of by-products, and enzymatic convertibility of the pretreated material. Wet oxidation led to the solubilisation of 82% of xylan and 50% of lignin, and to a two-fold increase of cellulose content in the pretreated solids, while steam explosion solubilised o...
متن کاملThe influence of variety type on dilute acid pretreatment-hydrolysis responses of sugarcane bagasse
This study evaluated the influence of variety type on dilute acid pretreatment and enzymatic hydrolysis responses in terms of xylose, glucose and total combined sugar yields of eight varieties of sugarcane bagasse. The pretreatment was carried out in small tubular reactors. The materials were pretreated under five different conditions and hydrolysed with a standard enzyme dosage (15 FPU/g water...
متن کاملComparison of Pretreatment Methods for Production of Ethanol from Sugarcane Bagasse
Sugarcane bagasse (SCB) was modified by steam explosion pretreatment at 190 °C for 10 min and 210 °C for 5 min using green liquor (GL) combined with hydrogen peroxide (GL-H2O2) and ethanol (GL-Ethanol) for simultaneous saccharification and fermentation (SSF)based ethanol production. The results showed that 85.02% and 100% of hemicelluloses were solubilized by steam explosion pretreatment at 190...
