    • The present invention provides a method for desorbing and regenerating a butanol-adsorbing hydrophobic macroporous polymer adsorbent, comprising: successively eluting the hydrophobic macroporous polymer adsorbent with butanol adsorbed therein using a water soluble low-boiling-point polar solvent and water. After a butanol-containing solution, such as a butanol fermentation liquor, has been adsorbed by a hydrophobic macroporous polymer adsorbent, the butanol adsorbed in the adsorbent can be thoroughly dissolved and removed by the desorption and regeneration method of the present invention; furthermore, the adsorbent can be directly regenerated to recover its adsorption capability on a fixed bed adsorbing the butanol fermentation liquor, wherein the next stage of adsorption process can be directly entered without taking the adsorbent out from the fixed bed; therefore it saves a great deal of time and improves the regeneration efficiency. The method provided in the present invention has a simple process, a short separation time, easy, fast and complete desorption and regeneration, low equipment investmentand pollution, and reduced energy consumption, and therefore production is easy on a large scale.
    • 本发明提供了一种用于解吸和再生丁醇吸附的疏水性大孔聚合物吸附剂的方法,其包括:使用水溶性低沸点极性溶剂和水连续洗脱其中吸附有丁醇的疏水性大孔聚合物吸附剂。 在丁醇发酵液等丁醇溶液被疏水性大孔聚合物吸附剂吸附后,通过本发明的解吸和再生方法可以使吸附剂中吸附的丁醇充分溶解除去, 此外,可以直接再生吸附剂以在吸附丁醇发酵液的固定床上回收其吸附能力,其中可以直接进入下一阶段的吸附过程而不将吸附剂从固定床中取出; 因此节省了大量的时间,提高了再生效率。 本发明提供的方法工艺简单,分离时间短,解吸和再生容易,快速,完整,设备投资少,污染少,能耗低,生产规模大。
