selectivity for the VFAs. Nitrogen-,stripping, with various temperature profiles was applied to regenerate the adsorbent, and study the potential for fractionation of the VFAs during regeneration. Butyric ,acid, (HBu) was obtained in mole fractions of up to 0.8 using a stepwise increase in the ,stripping, temperature from 25 °C via 120 to 200 °C.
