“…Adsorption data of butanol are mostly available in conjuncture with the recovery of ethanol and acetone. ,,, However, the selectivity of the adsorption processes also is dependent on the binding capacity of the adsorbent for water. For zeolites, the water adsorption capacity is listed in Table .…”

The microbial production of 1-butanol occurs in aqueous fermentation broth, with up to ∼20 g/L of product. Efficient recovery of butanol from this dilute aqueous phase determines, to a large extent, the efficiency of the production process. Starting from the thermodynamic (phase) properties of butanol and water systems, this paper presents a structured approach to determine the key characteristics of various butanol recovery methods. Analysis of reported separations, combined with fundamental phase properties, has resulted in both the characterization of the selectivity of recovery and estimations of the energy requirement during product recovery for a variety of recovery methods. Energy-efficient systems for the recovery of butanol from aqueous solution are pervaporation-and adsorption-based techniques. The applied method predicts the recovery energy requirement for both techniques to be <4 MJ/kg of butanol, which, on an energy basis, is similar to ∼10% of the internal combustion energy of butanol.

“…Conventional distillation is the usual way to recover butanol from the fermentation broth but it is highly energy‐intensive: at least 12 t of steam, 18 t of water, and 700 kWh of electricity are required per ton of ABE mixture recovered 6. Alternatives such as gas stripping 7, 8, pervaporation 9, adsorption 10, 11, and supercritical extraction 12 have been proposed over the last few years 13. The so‐called porocritical extraction process first developed by Robinson and Sims 14, 15 offers an interesting approach to the extraction of volatile organics present in low concentrations from aqueous streams by combining the porosity and high surface area of a hollow‐fiber membrane (HFM) contactor using hydrophobic polymeric membranes with the high diffusivity of a supercritical or near‐critical fluid.…”

Porocritical extraction was applied to the separation of 1-butanol and acetone from aqueous solutions modeling a typical acetone-butanol-ethanol (ABE) fermentation broth. The efficiency of two lab-scale hollow-fiber membrane contactors of different was studied under various flow rates, solvent-to-feed ratios, and pressure conditions. Global and individual, i.e., tube side, membrane, and shell side mass transfer coefficients were determined. The main contribution to mass transfer resistance was found in the shell side in all cases, and experimentally determined shell side mass transfer coefficients were compared to values predicted by existing correlations.
