This article reviews the production of renewable aviation fuels from biomass and residual wastes using gasification followed by syngas conditioning and Fischer-Tropsch catalytic synthesis. The challenges involved with gasifying wastes are discussed along with a summary of conventional and emerging gasification technologies. The techniques for conditioning syngas including removal of particulate matter, tars, sulphur, carbon dioxide, compounds of nitrogen, chlorine and alkali metals are reported. Recent developments in Fischer-Tropsch synthesis, such as new catalyst formulations are described alongside reactor technologies for producing renewable aviation fuels. The energy efficiency and capital cost of converting biomass and residual wastes to aviation fuels are major barriers to widespread adoption. Therefore, further development of advanced technologies will be critical for the aviation industry to achieve their stated greenhouse gas reduction targets by 2050.
本文综述了利用气化法，通过合成气调节和费托催化合成，从生物质和残余废物中生产可再生航空燃料的方法。讨论了气化废物所涉及的挑战，并概述了常规和新兴的气化技术。介绍了用于调节合成气的技术，包括去除颗粒物、焦油、硫、二氧化碳、氮化合物、氯和碱金属。描述了费托合成的最新进展，例如新型催化剂配方，以及用于生产可再生航空燃料的反应器技术。将生物质和残余废物转化为航空燃料的能源效率和资本成本是广泛采用的主要障碍。因此，为了实现航空业到 2050 年温室气体减排目标，进一步开发先进技术将是至关重要的。
