Study the fuel characteristics of ethanol and waste engine oil pyrolytic oil blends

This study shows the application of pyrolytic oil derived from waste engine oil (WEOPO) as an alternative fuel by blending with ethanol. For this, the effect of blending of ethanol at 5 %, 10 %, 15 %, 20 %, 25 %, and 30 % on the compositions and fuel properties were analyzed. The utmost blending was established based on the higher heating value. The pyrolytic oil used for this study was produced at 550 °C which was the optimum pyrolytic temperature. A comparison study of the blended oil was performed with commercially available gasoline to observe the similarities in their fuel properties and composition. The study confirmed that ethanol can be blended with WEOPO at 20 % by volume to obtain a fuel of a higher heating value of about 44.24 MJ/kg that can be used as fuel. Since WEOPO contains 65.80 % of C4–C12 (gasoline range), hydrocarbon compounds and the rest 31.48 % C11–C15, 11.84 % C15–C19, and 6.94 % > C19 compounds, it can be used as a future fuel.
