Pretreatment and enzymatic process modification strategies to improve efficiency of sugar production from sugarcane bagasse
Pretreatment and enzymatic hydrolysis play a critical role in the economic production of sugars and fuels from lignocellulosic biomass. In this study, we evaluated diverse pilot-scale pretreatments and different post-pretreatment strategies for the production of fermentable sugars from sugarcane bagasse. For the pretreatment of bagasse at pilot-scale level, steam explosion without catalyst and ...
متن کاملMicrowave-Assisted Green Production of Furfural from D-xylose of Sugarcane Bagasse
D-xylose is a component of sugarcane bagasse that can be used as a renewable resource for the production of a variety of chemicals. By means of catalytic reactions in an aqueous medium, it was determined that D-xylose can efficiently be converted into furfural by the application of microwave as a green synthetic methodology. The highest yields of furfural were obtained at a HCl concentration of...
متن کاملCharacterisation of Non-Cellulosic Heteropolysaccharide from Sugarcane Bagasse - Sequential Extraction with Steam Pretreatment and Alkali
Two-stage treatments of sugarcane bagasse with steam and alkaline peroxide were performed and the hemicelluloses extracted were characterized by chemical methods, SEC-MALLS, FT-IR and 13C NMR. The hemicellulose from steam pretreatment was found to contain galacto-arabinoxylans while alkaline peroxide extraction yielded predominately linear arabinoxylans.The present studyshowed a promising seque...
متن کاملFactors Affecting Delignification of Oil Palm Empty Fruit Bunch by Microwave-assisted Dilute Acid/Alkali Pretreatment
Microwave-assisted dilute acid/alkali pretreatment is an efficient and rapid method of removing lignin and hemicellulose, however, the optimized parameters for the maximum efficiency have to date not been presented in the literature. The purpose of this study was to determine those conditions by examining the effects of three factors: microwave power, temperature, and time on delignification in...
متن کاملDilute Acid pretreatment of corncob for efficient sugar production.
Aqueous dilute acid pretreatments of corncob were conducted using cylindrical pressure vessels in an oil bath. Pretreatments were conducted in a temperature range of 160-190 °C with acid-solution-to-solid-corncob ratio of 2. The acid concentration (v/v) in the pretreatment solution was varied from 0% to 0.7%, depending on temperature. This gives acid charge on ovendry-weight corncob of 0-2.58%....
