Abstract: Oxygenated fuel additives are added to gasoline in order to reduce the gases released from vehicle engines, to increase the octane number, and to expand the use of renewable resources. In this study, molecular and geometric analysis of oxygenated fuel additives was conducted theoretically and the energy values of optimized structures were calculated. The effect of molecular energy and the bond structure between C, H and O on the chemical and physical properties of some oxygen fuel additives were investigated. … Show more

Biofuels are fuels of biological origin, and they are among the prominent energy sources from renewable energy sources in recent years. Unlike fuels such as petroleum derivatives, coal, natural gas, biofuels are renewable and sustainable energy sources. Biofuels can be obtained by thermochemical or biochemical methods from agricultural and forestry products, animal and vegetable residues and wastes, organic origin domestic, industrial and urban wastes. Global warming caused by greenhouse gas effect is today shown as the most important common environmental problem in the world. The most important advantage of using biofuels in environmental terms is that there will be a reduction of greenhouse gas impact and acid rain. In this study, it is aimed to produce and characterize jet fuel by converting from pumpkin (Cucurbita pepo) seed oil, which is a sustainable bio energy source, into biofuel, by transesterification method. It has an important place in matters such as environment, sustainability, and reduction of carbon emissions. Biojet fuel produced using pumpkin seed oil, which is a sustainable resource, is a candidate product for development and commercialization.

The use of petroleum-based fuels in air transport and the increase in oil prices over the years have increased fuel costs. Due to this increase, fuel manufacturers and airline companies have started to search for alternative fuels. Since aviation has an important place in the transportation sector, biomass has the greatest potential in the search for renewable energy sources. Biological substances of plant and animal origin and containing carbon compounds are energy sources, and the fuels produced from them are called biofuels. Biofuels are an important source of sustainable energy, which greatly reduces the greenhouse gas effect, improves weather conditions, reduces dependence on oil produced from fossil fuels, and is important for new markets. The nettle seed oil used in the current study was purchased from the local market and was obtained using the cold-pressing method at low temperatures. After the completion of the transesterification process, a two-phase mixture consisting of biofuel-glycerin was obtained, and the upper phase containing fatty acids was taken and transferred to a clean tube. After the final washing processes, bio jet fuel was obtained by adding chemicals at certain rates. The analysis of the obtained fuel was conducted at the Tubitak Marmara Research Centre. When the report was evaluated and compared with international standards, consistent results were obtained. It can be predicted that sustainable fuels can replace fossil fuels in the future.
