Determination of some fuel properties of binary biodiesel and binary biodiesel – diesel blend fuels obtained from camelina oil and waste frying oils

Abstract

In today's studies on liquid biofuels, it is observed that many of them focus on blends of single biodiesel with diesel. These studies have shown that biodiesel produced from different feedstocks exhibits similar properties to traditional diesel fuel in terms of fuel characteristics and engine performance, indicating the potential of biodiesel to replace diesel fuel. However, recent research has shown limited studies involving the blending of dual biodiesel with traditional diesel fuel. In this study, high oil content camelina plant, which has an important place in ensuring sustainability in human food production, in other words, it is not suitable for human food and has the potential to significantly increase our domestic biofuel production, and domestic waste frying oil, which significantly reduces the cost of biodiesel raw material production, were selected as biodiesel feedstock. Binary biodiesel fuels (D0C50WF50, D0C75WF25, and D0C25WF75) were obtained by mixing the biodiesel fuels produced from camelina and domestic waste frying oil by transesterification method in the ratio of 1:1 and 1:3 by volume. Binary biodiesel-diesel blend fuels were obtained by blending binary biodiesel fuels (D75C12.5WF12.5, D50C25WF25 and D25C37.5WF37.5) with conventional diesel fuel (diesel) after blending at 1:1 ratio by volume. As a result of the research, the physicochemical properties (density, kinematic viscosity, flash point, water content, calorific value, cold filter plugging point, cloud and pour point, copper strip corrosion) of the prepared binary biodiesel and binary biodiesel+diesel blend fuels were determined. The results of the analyses of the blend fuels were determined in accordance with the relevant biodiesel standards (EN 14214, ASTM D-6751) and the results were also compared with the reference fuel, diesel fuel.
