Study finds higher ethanol yields when corn is mixed with sorghum

May 13, 2013 |

In Texas, Sorghum Checkoff in collaboration with the NCERC at Southern Illinois University Edwardsville (formerly the National Corn-to-Ethanol Research Center) is pleased to announce a successful bench-scale evaluation of sweet sorghum juice sugars with corn mash for the production of fuel ethanol. This study expands upon a commercial-scale trial that was conducted in Hopkinsville, Ky., in late 2012 by Commonwealth Agri-Energy LLC, Delta BioRenewables LLC, Ceres Inc. and the Sorghum Checkoff.

The bench-scale study yielded critical data on the production of ethanol from a combination of the two feedstocks by evaluating fermentation performance at different levels of sweet sorghum juice inclusion in corn mash. The sugar juice was successfully used as a replacement for process water, demonstrating the potential for a corn ethanol plant to increase production above nameplate capacity by incorporating sweet sorghum juice sugars.
