摘要： A process for regenerating a molecular sieve absorbent bed used for dehydrating an organic solvent is disclosed. The process is illustrated by regenerating a molecular sieve bed used for dehydrating ethanol, which includes a dehydrating cycle where an ethanol/water vapor mixture is loaded onto the molecular sieve bed at a first temperature to absorb water and recover a substantially dehydrated ethanol vapor effluent. In a regeneration cycle, the bed is subjected to a temperature swing technique whereby a dried gas, such as dried CO2, heated to at a second temperature greater than the first temperature, is passed over the molecular sieve bed, optimally in a counter current directional flow with respect to the dehydrating cycle. The process obviates the need for applying a vacuum pressure swing to regenerate the molecular sieve bed. Water and residual ethanol are removed with the CO2 effluent and can optionally be condensed and combined with a feed input for a subsequent dehydrating cycle.
