Abstract

The production of bioethanol and ethylene offers significant potential as carbon-neutral fuel and raw material e.g., for polyethylene production, respectively. We present a new approach, where we combined a) the bioethanol production process (pretreatment, hydrolysis, fermentation), b) the ethanol purification under the consideration of trace compounds and their removal to reach solvent-grade ethanol, and c) the coupling of the ethylene process to the ethanol process. The simulation results showed the feasibility of a flexible hybrid production process that fulfills the high-purity grades of both products. In addition, there is a high heat integration potential for all product ratios, thereby offering significant potential for adaptation to different market situations.
