Interpretive Summary:

Technical Abstract: The bioethanol industry has been experiencing rapid growth over the last several years and is expected to continue to increase production for the foreseeable future. A vital component to the success of this industry is the sales and marketing of processing residues, which are increasingly being sold as dried distillers grains with solubles (DDGS). This paper discusses a new initiative aimed at assessing liquefaction as a potential mechanism for converting these residues into valuable bio-polyols, which could partially replace petroleum-based feedstocks for the production of industrial fuels, chemicals, or chemical intermediates. Factors such as temperature, residence time, reagent and catalyst loading, as well as residue loading will be discussed, as will their effects on the resulting bio-polyol characteristics.
