Modification of jet fuels composition with renewable bio-additives

Synthesis of Camelina oil ethyl esters as components of jet fuels

“…Later, the content of Camelina oil ethyl esters in the transesterification products, as well as their fatty acid composition, was determined by gas chromatography. In addition, the fatty acid composition of the sample of rapeseed oil ethyl esters (RapEE) that was studied by the authors in previous researches [18][19][20] as a component of jet fuel, has been determined.…”

“…It is known from a number of studies [5,9,18,19] that fatty acid methyl esters (FAME) are widespread as an alternative fuel for diesel engines. However, one of the main unsolved issues regarding the use of FAME as components of jet fuel is their unsatisfactory low-temperature properties [18][19][20]. Thus, it was shown that due to the high freezing point, the use of jet fuels containing only 10 % vol.…”

“…In addition, fuel mixtures containing FAME demonstrate satisfactory compatibility with aircraft construction materials. However, the disadvantage of Oxygen content [16,20] in the FAME composition (about 11 %) is the reduction of their energy content compared to fuel of hydrocarbon origin.…”

“…A solution to the problem of improving low-temperature properties of biocomponents is the application of higher molecular weight alcohols for transesterification. From the studies [18,20,21], it is known that the nature of alcohol used for transesterification strongly affects the physical-chemical properties of the obtained esters. From the studies devoted to the development of biodiesel fuels based on fatty acid ethyl esters (FAEE) of plant oils, it is known [13,17] that increasing the hydrocarbon chain length of alcohol causes reduction of esters' freezing point [16,20].…”
