| Abstract | One factor hindering the economic feasibility of butanol fermentation is the energy intensity of the product separation. In this study a new approach for liquid-liquid extraction is presented. Gasoline additives were tested in conjunction with isooctane as extraction solvents, and a continuous process utilizing a novel, dual extraction is proposed. This method enables the usage of effective, nonbiocompatible solvents in ABE extraction without fear of inhibiting the microbes. The product mixture of this process could be utilized as a gasoline additive. No product purification steps are necessary, and very low energy consumption is achieved. The best extraction solvent was either MTBE or ETBE, depending on the operational parameters of the process. |
