  • Purification of isoprene from renewable resources
    Patent number: 9751820
    Abstract: Methods and apparatus for the purification of isoprene, such as the purification of a bioisoprene composition from fermentor off-gas. The apparatus includes two columns that process the fermentor off-gas, which includes isoprene and various impurities. A solvent is added to the off-gas in the first column, and the isoprene is stripped from the solvent in the second column. Also provided is a downstream further purification process. Also provided are the resulting purified isoprene compositions.
    Type: Grant
    Filed: April 9, 2015
    Date of Patent: September 5, 2017
    Assignees: Danisco US Inc., The Goodyear Tire & Rubber Company
