碩士 === 大葉大學 === 環境工程學系碩士班 === 101 === The study made use of agricultural wastes to produce bio-ethanol as alternative energy. Hydrolysis effect of Acacia confuse by different sulfuric acid concentration, temperature and reacting time was studied .enzyme and brewer's yeast Saccharomyces cerevisiae. Were added to the cellulose to explore optimization of alcohol production rate.The optimum hydrolysic conditions were: reacting temperature of 121 ℃﹐sulfuric acid concentration of 3% with a reaction time of 20 min. Under these condition, hydrolysate contained 10.92 g/L glucose, 61.16 g/L xylose and 0.07 g/L furfural﹐Through the operation of simultaneous saccharification and fermentation (SSF) experiment may produce ethanol 0.42 g / L for batch within 48 hr, while 0.45 g / L.
