  • Butanol Purification
    Publication number: 20180016215
    Abstract: Provided are methods for removing one or more components from a butanol based composition. The methods comprise providing a butanol based composition comprising one or more components, targeting at least one component or a combination thereof for reduction, and processing said butanol based composition such that the at least one targeted component is substantially removed. The butanol based composition can, for example, be bio-produced.

  • Method for Producing Butanol Using Extractive Fermentation
    Publication number: 20170057894
    Abstract: The invention relates to a method for producing butanol through microbial fermentation, in which the butanol product is removed by extraction into a water immiscible organic extractant during the fermentation. The invention also relates to a method for producing butanol through microbial fermentation, in which the butanol product is removed during the fermentation by extraction into a water-immiscible extractant composition. The invention further relates to compositions comprising a solution of butanol in a water immiscible organic extractant composition.
