Creation a novel promising technique for producing an unleaded aviation gasoline 100UL

Even though tetraethyl lead (TEL) is the most effective of the known antiknock additives, especially in aviation gasoline, there has been a clear tendency to abandon its use. This present work investigates the creation of a novel promising technique for producing an unleaded aviation gasoline 100UL through studying the influence of various aromatic amines, aromatic hydrocarbons, and MTBE on the antiknock characteristics of model blends of isooctane and n-heptane. Additionally, a nonlinear change in the antiknock performance of aromatic amines was established as the detonation resistance of the base fuel increased with the essential role of the structure of the aromatic amine. The results indicated that the optimal composition of the produced fuel was contained 57 wt% of isooctane, 10 wt% of isopentane, 10 wt% of toluene, 5 wt% of isopropylbenzene 15 wt% of MTBE, 2 wt% of m-toluidine, and 1 wt% of isopropyl alcohol. What's more, its characteristics were as close as possible to the properties of commercial aviation gasoline 100VLL and it did not contain other metal-containing additives. Finally, the concentrations of non-hydrocarbon additives, such as m-toluidine and MTBE were within the range that has been tested on an industrial scale during the operation of an automotive equipment in many countries of the world.

Automated summary

This study investigates the influence of aromatic amines, aromatic hydrocarbons, and MTBE on the antiknock characteristics of model blends to create a novel technique for producing unleaded aviation gasoline. The results indicate that the optimal fuel composition contains isooctane, isopentane, toluene, isopropylbenzene, MTBE, m-toluidine, and isopropyl alcohol, with characteristics close to commercial aviation gasoline. Furthermore, the non-hydrocarbon additives concentrations tested in this study have been used on an industrial scale in various countries.
