Abstract

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. The method provided in the present invention has a simple process, a short separation time, easy, fast and complete desorption and regeneration, low equipment investment and pollution, and reduced energy consumption, and therefore production is easy on a large scale.
