“…Although most applications of MFI zeolites so far have been as adsorbent/catalyst for hydrocarbon separations or reactions, MFI zeolite has shown great potential for recovering biobutanol from fermentation broths, and other applications for separating organics from water solutions will most likely emerge [6]. Therefore, a thorough understanding of the behavior of water in MFI zeolite is important.…”

“…In this study four kinds of AC (original and chemically modified active carbon by hydrothermal H 2 O 2 reaction) were investigated for their absorption and desorption behavior with butanol vapor. In addition, the zeolite ZSM-5 was used as a control, since it is known that zeolites are good adsorbents to recover butanol from aqueous solutions [33].…”

a b s t r a c tButanol is considered a promising, infrastructure-compatible biofuel. Unfortunately, the fermentation pathway for butanol production is restricted by its toxicity to the microbial strains used in the process. Gas stripping technology can efficiently remove butanol from the fermentation broth as it is produced, thereby decreasing its inhibitory effects. Adsorption can then be used to recover butanol from the vapor phase. Active carbon samples and zeolite were investigated for their butanol vapor adsorption capacities. Commercial activated carbon was modified via hydrothermal H 2 O 2 treatment, and the specific surface area and oxygen-containing functional groups of activated carbon were tested before and after treatment. Hydrothermal H 2 O 2 modification increased the surface oxygen content, Brunauer-Emmett-Teller surface area, micropore volume, and total pore volume of active carbon. The adsorption capacities of these active carbon samples were almost three times that of zeolite. However, the un-modified active carbon had the highest adsorption capacity for butanol vapor (259.6 mg g −1 ), compared to 222.4 mg g −1 after 10% H 2 O 2 hydrothermal treatment. Both modified and un-modified active carbon can be easily regenerated for repeatable adsorption by heating to 150 • C. Therefore, surface oxygen groups significantly reduced the adsorption capacity of active carbons for butanol vapor.

“…However, as the adsorption of the acids is decreased at high pH, the adsorption of acetone increases, whereas adsorption of ethanol decreases. This is expected as acetone shows higher affinity towards high-silica MFI than ethanol [16,18,20]. Tables 3 and 4 show the batch adsorption experiment results from modified black liquor fermentation broth at pH 5.2 and 8, respectively.…”

In this work, high-silica MFI zeolite adsorbent was evaluated for selective recovery of butanol from a real ABE (acetone, butanol, and ethanol) fermentation broth by batch adsorption measurements. The fermentation broth was produced using a hydrolyzate originating from Kraft black liquor, an internal stream in pulp mills, i.e., a low-cost substrate. The adsorbent was very selective towards butanol and butyric acid and became nearly saturated with a mixture of butanol and butyric acid with relative amounts of butanol and butyric acid depending on the pH. The presence of phenolic compounds in significant amounts in the fermentation broths, originating from the black liquor hydrolyzate, did not affect the adsorption of butanol and butyric acid.
