Improvement of Air Transport Environmental Safety by Implementing Alternative Jet Fuels

The study is devoted to evaluation of exhaust gases emissions from aircrafts using conventional oil-derived jet fuel and alternative jet fuels, obtained by blending of conventional fuel with plant oil bio-additives. The evaluation was done by calculation of emission indexes of carbon dioxide, water vapor, sulfur oxide and nitrogen oxide and calculation of emission levels of each pollutant in a result of one standard landing - take-off cycle. In a result of the study it was found that samples of alternative jet fuels blended with plant oil bio-additives are characterized by lower emission level comparing to conventional jet fuels. These alternative jet fuels may also provide reduction of total emissions levels. Thus it was concluded that application of alternative jet fuels containing plant oil bio-additives may contribute to improvement of environmental safety of modern air transport.
