Co2 from ethanol production
Carbon dioxide from fermentation can be captured at a relatively low cost, requiring only dehydration and compression. 16 Unlike other CO 2 point sources, ethanol production generates a high purity (99%) stream of fermentation CO 2 containing only CO 2, H 2 O, and small amounts of sulfur and organic compounds. 17,18 The technical …Multi-carbon alcohols such as ethanol are valued as fuels in view of their high energy density and ready transport.

Feb 8, 2017 · A reduction in U.S. ethanol production (for example, in response to policy changes) would inadvertently pose a significant disruption to the billion-dollar carbon dioxide industry, and the U.S. food industry. Fermentation from corn-ethanol plants is the largest single-sector CO2 source for the U.S. merchant gas markets. In the chemostat that was initially fed with a mixture of 50% starch and 50% glucose (20 g/L each), the reactor produced a mixture of lactic acid, ethanol, and acetate. Again, switches to full starch feed and full glucose feed caused an immediate shift towards lactic or ethanolic fermentation, respectively (Fig. 2 B).
