Bio-based butanol has superior properties when compared to ethanol to be the gasohol and is gradually considered to be an important biofuel from the biomass fermentation of ABE solution. The potential sorbents for acetone (A), 1-butanol (B), and ethanol (E) recovery process will be analyzed by the isotherm data and the sorbents, such as potato starch sorbent and ZSM-5 will be selected. The above sorbents to adsorb acetone, 1-butanol, and ethanol for single-component adsorption using adsorption equilibrium apparatus will be conducted and the isotherm data will be obtained.

The single-component adsorption equilibrium of VOCs on activated carbon was studied. Results show that the adsorption isotherms of benzene, toluene, ethyl acetate and acetone on activated carbon all fall into type I, according with the characteristics of micropore volume filling, and the Langmuir equation proves to be the best for the fitting of experiments data. The adsorption equilibrium of different adsorbates on the same adsorbent can be predicted by the D-R equation with affinity coefficients, and the prediction precision depends on the calculation method of affinity coefficients. Of the three calculation methods, the method of molar volume is the most precise, secondly the method of parachors, and thirdly the method of molecular polarizability, with average errors 5.9%，10.2% and 27.8% respectively.
