This study develops and applies the PROMETHEE-GAIA method as a new tool to select microalgae strains for aviation fuel production. Assessment involves 19 criteria with equal weighting in three aspects, namely biomass production, lipid quality, and fatty acid methylester properties. Here, the method is demonstrated for evaluating 17 candidate microalgae strains. Chlorella sp. NT8a is assessed as the most suitable strain for aviation fuel production. The results also show that unmodified biofuel from the most suitable strain could not meet all jet fuel standards. In particular, microalgae-based fuel could not satisfy the required density, heating value and freezing points of the international jet fuel standards. These results highlight the need for a broad action plan including improvement in the processing or modification of biofuel produced from microalgae and revision of the current jet fuel standards to facilitate the introduction of microalgae-based biofuel for the aviation industry.
本研究开发并应用了PROMETHEE-GAIA方法，作为一种选择用于航空燃料生产的微藻菌株的新工具。评估涉及19项标准，在生物质产量、脂质质量和脂肪酸甲酯特性三个方面具有同等权重。在此，该方法用于评估17种候选微藻菌株。小球藻NT8a被评估为最适合用于航空燃料生产的菌株。结果还表明，来自最合适菌株的未改性生物燃料不能满足所有喷气燃料标准。特别是，基于微藻的燃料无法满足国际喷气燃料标准所要求的密度、热值和冰点。这些结果凸显了制定广泛行动计划的必要性，包括改进微藻生产生物燃料的加工或改性，以及修订当前的喷气燃料标准，以促进基于微藻的生物燃料在航空业中的引入。
