1-Butanol can be produced by clostridial fermentations with acetone and ethanol as by-products The butanol can be present up to similar to 20 g L-1 depending on process conditions and microbial strain The high-silica zeolite CBV28014 has been proven to adsorb butanol selective over water, while showing higher affinity for butanol than for acetone and ethanol Multi-component acetone-butanol-ethanol (ABE) adsorption on CBV28014 has been modeled using a single site extended Langmuir adsorption model and the ideal adsorbed Solution (IAS) theory model The IAS model describes multi-component adsorption of ABE in synthetic mixtures and ABE in filtered fermentation broth by CBV28014 more accurately than the single site extended Langmuir model (C) 2009 Elsevier B V All rights reserved
