Method for the recovery of ethanol during fermentation |
摘要 |
Producing ethanol, comprises: (a) carrying out fermentative conversion of sugar with 5 carbon atoms or 5-6 carbon atoms to ethanol in a fermentation solution; (b) utilizing a carrier gas for in situ-removal of ethanol by gas stripping, where the ethanol concentration in the fermentation solution is less than 5% (in wt./vol.); (c) directing the ethanol-carrier gas mixture obtained by gas stripping through a zeolite adsorber, where the ethanol is adsorbed by the adsorber from the gas mixture; and (d) carrying out the desorption of adsorbed ethanol from the adsorber.
