Abstract: | The burning of kerosene in jet turbines is investigated for two reference flights with a Boeing 747-400 and an Airbus A320-200,
representing the typical Lufthansa planes for long and middle distance. The ecological evaluation is performed by Life Cycle
Assessment (LCA). Formation of condensation trails, which is a specific environmental impact caused by air traffic, has to
be considered in addition to established LCA impact categories. Based on the ecological assessment, an improvement assessment
is performed. Environmental performance of diesel fuel during the combustion in car engines is analysed based on available
publications. The relevant parameters for the environmental impact of the combustion of diesel (aromatics content, reduction
of sulphur content, the reduction of the density and raising of the cetane number) are discussed with regard to improvements
of the exhaust qualities of kerosene. A reduction of the aromatics content promises to improve the emission of soot which
should be further investigated. |
