A novel bio-based activated carbon was synthesized from vine shoot, an agricultural waste, by chemical activation method using NaOH as activating agent. Adsorption of acetone, butanol and ethanol (ABE), as main products in ABE fermentation, in the single and multicomponent systems were measured. The experiments were carried out in both equilibrium and dynamic conditions and selectivity of the adsorbent was calculated, accordingly. The adsorption kinetics of the synthesized adsorbent were also investigated. Based on the obtained results, the synthesized activated carbon (AC) shows a very high butanol loading (about 520 mg/g at 10 g/l butanol equilibrium concentration). High butanol selectivity over ethanol and acetone (10.31 and 7.66, respectively), obtained from multicomponent equilibrium experiments, indicated that the vine shoot based activated carbon showed the high affinity toward butanol. This result was also approved by ABE multicomponent breakthrough experiment in which adsorbed ethanol and acetone displaced by butanol during the adsorption process. High butanol capacity, fast equilibrium time, and excellent butanol affinity, makes the synthesized activated carbon a great candidate for butanol adsorption from ABE fermentation products.

以农业废弃物藤茎为原料，以NaOH为活化剂，采用化学活化法合成了一种新型生物基活性炭。对作为 ABE 发酵主要产物的丙酮、丁醇和乙醇 (ABE) 在单组分和多组分系统中的吸附进行了测量。实验在平衡和动态条件下进行，并相应地计算吸附剂的选择性。还研究了合成吸附剂的吸附动力学。根据获得的结果，合成的活性炭 (AC) 显示出非常高的丁醇负载量（在 10 g/l 丁醇平衡浓度下约为 520 mg/g）。从多组分平衡实验中获得对乙醇和丙酮的高丁醇选择性（分别为 10.31 和 7.66），表明基于葡萄枝的活性炭对丁醇显示出高亲和力。这一结果也得到了 ABE 多组分突破实验的认可，其中在吸附过程中吸附的乙醇和丙酮被丁醇置换。高丁醇容量、快速平衡时间和出色的丁醇亲和力，使合成的活性炭成为从 ABE 发酵产物中吸附丁醇的绝佳候选者。
