| 摘 要： | 提出了乙醇气提发酵与载气蒸馏耦合的新过程. 采用载气循环满足了发酵所要求的较低温度和蒸馏所需的较大汽化量，载气就地带走乙醇从而降低了产物浓度，减小了产物对酵母的抑制.采用内循环气升式反应器和板式蒸馏塔实验验证了该过程的可行性.

| Abstract: | A new process for ethanol production is proposed in which gas stripping fermentation is coupled with carrier gas distillation. Fermentation usually needs to be operated at low temperature while distillation requires large amount of evaporation. The circulation of carbon dioxide meets both requirements and makes the coupling of fermentation with distillation possible. The feasibility of the proposed process was experimentally verified using an air-lift fermentor with a plate type distillation column on the top. |
