摘要
对甜高粱茎秆原料生产燃料乙醇的工艺条件、残渣综合利用等进行了研究,确定了甜高粱茎秆汁液发酵生产燃料乙醇的最佳工艺条件:高粱汁锤度为20°Bx(糖度17.8%)、接种量为10%、pH值4.5、发酵时间48 h,发酵醪的酒精浓度可达10.2%以上,残糖1%以下。
The technical conditions of fuel ethanol production by sweet sorghum stalk and the comprehensive use of the production residue were studied. Besides, the optimum technical conditions of fuel ethanol production by sweet sorghum stalk juice fermentation were determined as follows： the brix of sorghum stalk juice as 20°Bx （sugar content was 17.8 %）, 10 % inoculation quantity, pH value was 4.5, and alcohol c0ncentra- tion could reach up to above 10.2 % after 48 h fermentation with residual sugar content less than 1%.
