Abstract
(EN)
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 capacity 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 investment and pollution, and reduced energy consumption, and therefore production is easy on a large scale.

La présente invention porte sur un procédé pour la désorption et la régénération d'un adsorbant polymère macroporeux hydrophobe adsorbant le butanol, comprenant l'élution successive de l'adsorbant polymère macroporeux hydrophobe renfermant du butanol adsorbé à l'aide d'un solvant polaire hydrosoluble de faible point d'ébullition et d'eau. Après qu'une solution contenant du butanol, tel qu'une liqueur de fermentation butanolique, a été adsorbée par un adsorbant polymère macroporeux hydrophobe, le butanol adsorbé dans l'adsorbant peut être totalement dissous et enlevé par le procédé de désorption et de régénération de la présente invention; en outre, l'adsorbant peut être directement régénéré pour récupérer sa capacité d'adsorption en lit fixe adsorbant la liqueur de fermentant butanolique, la phase suivante du procédé d'adsorption pouvant entrer directement sans retirer l'adsorbant du lit fixe; par conséquent cela permet d'économiser beaucoup de temps et cela améliore l'efficacité de la régénération. Le procédé de la présente invention a un processus simple, un temps de séparation court, une désorption et une régénération faciles, rapides et totales, un faible coût d'investissement en matériel et une faible pollution et il presente une consommation d'énergie réduite et par conséquent la production est facile à une grande échelle.
