Purified Butanol from Lignocellulose – Solvent‐Impregnated Resins for an Integrated Selective Removal

Abstract: In traditional microbial biobutanol production, the solvent must be recovered during fermentation process for a sufficient space‐time yield. Thermal separation is not feasible due to the boiling point of n‐butanol. As an integrated and selective solid‐liquid separation alternative, solvent impregnated resins (SIRs) were applied. Two polymeric resins were evaluated and an extractant screening was conducted. Vacuum application with vapor collection in fixed‐bed column as bioreactor bypass was successfully implemented as butanol desorption step. In course of further increasing process economics, fermentation with renewable lignocellulosic substrates was conducted using Clostridium acetobutylicum. Utilization of SIR was shown to be a potential strategy for solvent removal from fermentation broth, while application of a bypass column allows for product removal and recovery at once.
