纤维乙醇发酵工艺的比较及放大试验研究
Study on Scale-up Experiment and Comparison of the Processes of the Cellulosic Ethanol Production
摘要
Abstract
Several processes of the SSF based on steam-exploded corn stalk were compared in this paper. The best process of the simultaneous saccharification and fermentation is in the condition of variable-temperature. In this condition the efficiency of the ethanol production improved by 7.56% compared with the simultaneous saccharification and fermentation, improved by 12.60% compared with the pre-hydrolysis of the fed-batch saccharification and fermentation, and improved by 23.07% compared with the score-step saccharification and fermentation. Besides the amplification of the variable-temperature simultaneous saccharification and fermentation test was studied in 50 L fermenter and the volume of ethanol is 4.26%. At the same time ,the variations of the concentration of yeast, the concentration of residual sugar and the alcohol content with time in scale-up experiment were also studied.关键词
