We develop a superstructure framework for the design of biorefineries for ethanol upgrading into advanced biofuels to replace gasoline, jet fuel or diesel. The framework integrates catalysis, process synthesis, and fuel property modelling towards the design of biorefineries producing fuels with specified properties. The proposed framework is applied to identify strategies for the upgrading of ethanol into one or more fuels with specific properties. We discuss the trade-off between profit and biorefinery complexity, as well as the relation among fuel property constraints, the optimal upgrading strategy selected, and process economics. Finally, we show how to find the optimal biorefinery associated with a particular chemistry or catalyst. The results presented constitute the first systematic study of ethanol upgrading considering, simultaneously, fuel and process design.

来自乙醇的高级燃料–上部结构优化方法

我们为生物精炼厂的设计开发了上层建筑框架，以将乙醇升级为高级生物燃料，以替代汽油，喷气燃料或柴油。该框架将催化，过程合成和燃料特性建模集成到生产具有特定特性的燃料的生物精炼厂的设计中。拟议的框架适用于确定将乙醇升级为一种或多种具有特定特性的燃料的策略。我们讨论了利润与生物炼制厂复杂度之间的权衡，以及燃料特性约束，选择的最佳升级策略和过程经济学之间的关系。最后，我们展示了如何找到与特定化学或催化剂相关的最佳生物精炼厂。提出的结果构成了同时考虑到
