Sustainably produced biofuels, especially when they are derived from lignocellulosic biomass, are being discussed intensively for future ground transportation. Traditionally, research activities focus on the synthesis process, while leaving their combustion properties to be evaluated by a different community. This Review adopts an integrative view of engine combustion and fuel synthesis, focusing on chemical aspects as the common denominator. It will be demonstrated that a fundamental understanding of the combustion process can be instrumental to derive design criteria for the molecular structure of fuel candidates, which can then be targets for the analysis of synthetic pathways and the development of catalytic production routes. With such an integrative approach to fuel design, it will be possible to improve systematically the entire system, spanning biomass feedstock, conversion process, fuel, engine, and pollutants with a view to improve the carbon footprint, increase efficiency, and reduce emissions.
可持续生产的生物燃料，尤其是源自木质纤维素生物质的生物燃料，正被广泛讨论，作为未来地面运输的燃料。传统上，研究活动主要集中在合成过程上，而将其燃烧性能留给其他领域的人员进行评估。这篇综述从发动机燃烧和燃料合成的综合角度出发，重点关注化学方面作为共同的基础。研究表明，对燃烧过程的深入理解有助于为燃料候选物的分子结构设计提供依据，这些依据又可以作为合成途径分析和催化生产路线开发的目标。通过这种燃料设计的综合方法，有可能系统地改进整个系统，涵盖生物质原料、转化过程、燃料、发动机和污染物，以改善碳足迹、提高效率和减少排放。
