摘要
设计了一种新型的带侧臂循环的气升式反应器,该反应器可以有效地把真空闪蒸发酵和汽提发酵2项技术结合起来。实验结果表明,与单独的汽提和闪蒸过程相比,利用此反应器进行同步汽提闪蒸操作,大大提高了乙醇的移出效率,从而进一步提高了发酵强度。
A novel air-lift bioreactor with a side arm loop is designed,which combines vacuum flash fermentation with gas stripping fermentation.The structure and the process of the bioreactor are introduced.Compared with the steam stripping or the flash fermentation,the gas stripping-flash coupling process with the bioreactor can improve the ethanol productivity with the ethanol removal increased greatly,and furthermore the fermentation intension enhanced.
