| Abstract: | Butanol fermentation is inhibited by butanol product,leading to low productivity,low product concentration and poor economic feasibility.In order to decrease the inhibition of butanol,PDMS/PVDF membrane was prepared for separating acetone,butanol and ethanol from aqueous solutions.Taking separation factor and flux as evaluating index,the effects of feed temperature,mass fraction and pH on pervaporation performance were investigated.The results indicate that the membrane separation performance ascends with i... |
