Cold Flow Properties of Biojet Fuels in Aviation

Cold flow properties are very important in terms of flight safety in both civil and military aviation fuels. The cold flow properties of biofuels are worse compared to currently used aviation fuels, but they are of great importance in terms of environment safety and emissions. When the studies done so far on a new biodiesel used in this study were examined, no study was found in the literature. The production method of Onopordum biodiesel was patented by the author with the Turkish Patent Institute’s document numbered 2022/05453. Biojet fuel was obtained by mixing Onopordum biodiesel with JP-8 fuel, which is a military aviation fuel, in certain proportions (B2, B3, B5). The cold flow properties of the obtained biojet fuel were tested and the results were presented. This study has been done for the first time in the world literature for the biofuel used in this study, and it is possible to test the additives added to the fuel mixtures at different rates or to produce different alternative fuels by diversifying the types of additives used.
