  Optimization of Sulphuric Acid Hydrolysis Process for Fermentable Sugars from Lignocellulosic Content of Wood Sawdust for Production of Cellulosic Ethanol

  By Gebreyohannes Gebrehiwot, Kiros Birhane, Tsegay Gebrekidan

  Abstract: The aim of this study was to investigate the optimization of acid hydrolysis process for fermentable sugars from the lignocellulosic content of wood sawdust for cellulosic ethanol production. In this study, four process parameters were investigated; acid concentration (3-7%), solid fraction (8-12ml/gm), temperature (100-120oC) and time (90-150minutes). The total reducing sugar content of hydrolyzed solutions was analyzed using Phenol-Sulfuric Acid method. The result of the statically analysis 2mm particle size …

  Production of Cellulosic Ethanol from Wood Sawdust by Sulphuric acid Hydrolysis

  By Gebreyohannes Gebrehiwot, Sekarathil Anuradha Jabasingh, Abubeker Yimam

  Abstract: In this study, production of cellulosic ethanol from wood sawdust was investigated. Four experimental parameters were investigated during the hydrolysis and ethanol production. These are particle size (1–3 mm), acid concentration (3–7%), temperature (90–110°C), and time(120–240 min). The total reduced sugar content and ethanol yield was determined. Response surface methodology (RSM) employing the central composite design (CCD) was used to optimize the total reduced sugar and ethanol yield. Cite this …
