Develop a two step fermentation process coupled with membrane separations (UF, ED and EDI) to

produce bio- butanol

Description:

Bench-scale experiments of continuous fermentation coupled with cell recycle and products

separation to produce butyric acid

Development of separation methods to selectively remove butyric acid from reactor, mainly

focusing on ion exchange and electrodialysis

Simulations of batch fermentation, continuous fermentation, and continuous fermentation with

products separation by developing mathematic models and solving them with Matlab

Process simulation of two step fermentation and sequential separations (including ultrafiltration,

electrodialysis, pervaporation and distillation) to produce bio-butanol by integrating developing

modeling and commercial simulator
