[EN] A vapor phase adsorptive recovery process is proposed
as an alternative way to isolate biobutanol from acetone-butanolethanol
(ABE) fermentation media, offering several advantages
compared to liquid phase separation. The effect of water, which is
still present in large quantities in vapor phase, on the adsorption of
the organics could be minimized by using hydrophobic zeolites.
Shape selective all-silica zeolites CHA and LTA were prepared and
evaluated via single component isotherms and breakthrough
experiments. These zeolites show an opposite selectivity; adsorption
of ethanol was favorable on all-silica CHA, while the LTA topology
had clear preference for butanol. The molecular sieving properties of
both zeolites allowed to easily eliminate acetone from the mixture.
The molecular interaction mechanisms were studied by density
functional theory (DFT) simulations. Effect of mixture composition,
humidity and total pressure of the vapor stream on the selectivity
and separation behavior was investigated. Desorption profiles were
studied to maximize butanol purity and recovery. The combination of
LTA with CHA type zeolites (Si-CHA or SAPO-34) in sequential
adsorption columns with alternating adsorption and desorption steps
allows to obtain butanol in unpreceded purity and recovery. A
butanol purity of 99.7 mole% could be obtained at nearly complete
butanol recovery, demonstrating the effectiveness of this technique
for biobutanol separation processes.
