近年来，通过催化研究提出了新的生物燃料候选物。为了有效地指导后续研究活动，必须评估大规模生产这种下一代生物燃料与乙醇等现有生物燃料相比是否具有竞争力。然而，为所有替代品提供完整的工艺设计非常耗时，特别是在早期开发阶段缺少重要数据的情况下。相反，最近引入了反应网络通量分析（RNFA）来快速筛选生产路线，以弥合催化研究和工艺设计之间的差距。使用这种方法，制定了可能的反应网络的质量平衡，使多目标优化技术可以应用于识别具有高性能的有吸引力的途径。典型的性能指标，如总的年度成本或环境影响，适应早期设计阶段的要求，并集成在通量分析。在本文中，生产性能指标的10个新的生物燃料候选人相比，甲醇，乙醇，丁醇，甲烷作为参考燃料使用RNFA。虽然一些途径已经显示出令人鼓舞的性能，但如果目标产物有资格成为有希望的候选燃料，则必须显著提高其他途径的反应产率。(c)2012年化学工业协会和约翰威利父子公司
Recently, novel biofuel candidates have been proposed by catalysis research. To guide follow-up research activities efficiently, it must be assessed whether large-scale production of such next-generation biofuels is competitive in comparison with established biofuels like ethanol. However, it is very time-consuming to provide complete process designs for all alternatives, especially as important data are missing in the early development phase. Instead, reaction network flux analysis (RNFA) has been introduced recently for rapid screening of production routes to bridge the gap between catalysis research and process design. Using this approach, mass balances are formulated for a network of possible reactions such that multi-objective optimization techniques can be applied to identify the attractive pathways with high performance. Typical performance indicators like total annualized cost or environmental impact are adapted to the requirements of the early design phase and integrated in the flux analysis. In this paper, production performance indicators of ten novel biofuel candidates are compared to those of methanol, ethanol, butanol, and methane as reference fuels using RNFA. While some pathways already show an encouraging performance, the reaction yield of others must be increased significantly, if the target product should qualify as promising fuel candidates.
