Aviation has been, before the sanitary crisis, one of the strongest growing transport sectors. Despite this crisis, this trend is predicted to continue (Neu 2020). One of the actual concerns of aviation industry is to reduce its impact on climate and air quality using for example Sustainable Aviation Fuels (SAF). As part of the UNREAL (Unveiling Nucleation mechanism in aiRcraft Engine exhAust and its Link with fuel composition) project, the objective of this work was to study and compare the chemical pattern, at a molecular level, of the gaseous and particulate phases of primary as well as secondary emissions from various aircraft fuels with distinct compositions.
