2012 ASABE Annual International Meeting
As the quantity of ethanol produced in the U.S. continues to expand, so too does the need for value-added applications for the resulting coproducts. Distillers dried grains with solubles (DDGS), corn gluten meal (CGM), and corn gluten feed (CGF) are the primary coproducts of ethanol manufacturing (which includes dry grind processing and wet milling). The main consumer of these coproducts is the livestock industry, which utilizes these materials as animal feed and ingredients due to their high nutrient contents, good palatability and digestibility, and relatively low cost; however, new value added uses are starting to arise. This study will examine the pyrolysis of DDGS and CGM. Extensive characterization of the resulting bio-oil included mass density, thermal conductivity, thermal diffusivity, apparent viscosity, and energy content. Potential opportunities for extracting value from these materials will also be explored and discussed.
