The aviation sector, a significant greenhouse gas emitter, must lower its emissions to alleviate the climate change impact. Decarbonization can be achieved by converting low-carbon feedstock to sustainable aviation fuel (SAF). This study reviews SAF production pathways like hydroprocessed esters and fatty acids (HEFA), gasification and Fischer-Tropsch Process (GFT), Alcohol to Jet (ATJ), direct sugar to hydrocarbon (DSHC), and fast pyrolysis (FP). Each pathway's advantages, limitations, cost-effectiveness, and environmental impact are detailed, with reaction pathways, feedstock, and catalyst requirements. A multi-criteria decision framework (MCDS) was used to rank the most promising SAF production pathways. The results show the performance ranking order as HEFA > DSHC > FP > ATJ > GFT, assuming equal weight for all criteria.
航空业是主要的温室气体排放源，必须降低其排放量以减轻气候变化影响。通过将低碳原料转化为可持续航空燃料（SAF）可实现脱碳。本研究综述了SAF的生产途径，如加氢处理酯和脂肪酸（HEFA）、气化和费托工艺（GFT）、醇制喷气燃料（ATJ）、直接糖制烃（DSHC）和快速热解（FP）。详细介绍了每种途径的优势、局限性、成本效益和环境影响，以及反应途径、原料和催化剂要求。使用多标准决策框架（MCDS）对最具前景的SAF生产途径进行排名。结果表明，在所有标准权重相等的情况下，性能排名顺序为HEFA > DSHC > FP > ATJ > GFT。
