OBTAINING DIESEL FUEL WITH IMPROVED PROPERTIES

Abstract

It is known that one of the ways to increase the level of operational properties of diesel fuels is the injection of special components – additives – into their composition. Today this way is a quite rational and economically feasible for Ukraine, especially in the absence of high-quality oil raw materials for the production of fuels, which in turn leads to a significant dependence on imports. The range of additives used in diesel fuels is very diverse, which makes it difficult to select a balanced package, especially considering their effectiveness and compatibility with each other. This procedure can be a bit simplified by adding poly-functional additives to diesel fuel, the use of which is devoted to a lot of periodical literature. Based on the relevance of the direction of scientific research related to improving the properties of diesel fuel, which is produced at the enterprises of the oil refining industry in Ukraine, we proposed to use a substance belonging to the class of aromatic diazocompounds and having polyfunctional properties in the composition of diesel fuels. Thus, this additive was added to a straight-run diesel fraction (240–350 °C) in an amount of up to 1.0%, followed by a study of the properties of the resulting mixture. Studies have shown that the additive significantly improves low-temperature properties (by -10 °C), contributes to an increase in fuel density and viscosity, and additionally gives diesel fuel a stable color (from yellow to orange). Consequently, it can be used in the composition of commercial diesel fuels with improved performance properties.
