Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
What is claimed is: 1. A method for desorbing and regenerating a butanol-adsorbing hydrophobic macroporous polymer adsorbent, the method comprising: successively eluting the hydrophobic macroporous polymer adsorbent with butanol adsorbed therein using a water soluble low-boiling-point polar solvent and water, wherein the hydrophobic macroporous polymer adsorbent with butanol adsorbed therein adsorbs butanol by adsorbing a butanol fermentation broth. 2. The me…
