Summary of the PhD project:

Air transport is a steadily growing sector, and this trend is expected to continue in the coming years. As a result, the impact of aviation emissions on climate and air quality is of great concern. Among the various solutions available, the aviation industry has identified the development of new alternative fuels as one of the main tools to reduce its emissions. Currently, six alternative fuel production streams are technically certified and many more are under review. In this context, this study aims to study the emissions of these different alternative fuels in order to establish a link between their emissions and their chemical composition.

In this work, different fuels will be studied including different Jet A-1 from different productions, biosourced kerosene produced from alcohol or esters, and mixtures at different rates between Jet A-1 and fuels. Alternative fuels with different levels of sulfur and aromatic compounds will also be studied. The measurement line used allows a study of the physical characteristics of volatile particles and nonvolatile particles, isolated with a catalyst heated to 350 ° C.

To complete the physical characterization of the particles, filter samples are taken upstream of the line to chemical characterize the emissions.
