摘要

Abstract

Pervaporation has attracted considerable interest owing to its potential application in recovering biobutanol from biomass acetone-butanol-ethanol(ABE)fermentation broth.In this study

butanol was recovered from its aqueous solution using a polydimethylsiloxane(PDMS)/ceramic composite pervaporation membrane.The effects of operating temperature

feed concentration

feed flow rate and operating time on the membrane pervaporation performance were investigated.It was found that with the increase of temperature or butanol concentration in the feed

the total flux through the membrane increased while the separation factor decreased slightly.As the feed flow rate increased

the total flux increased gradually while the separation factor changed little.At 40℃ and 1%(by mass) butanol in the feed

the total flux and separation factor of the membrane reached 457.4 g·m

·h

-1

and 26.1

respectively.The membrane with high flux is suitable for recovering butanol from ABE fermentation broth.
