Comparison of the Properties of Biodiesel-Bioethanol-Diesel Blended Fuel

Abstract

Energy production relies on finite fossil fuels and is usually regarded as the primary source of hazardous emissions and global warming. As a result, much attention has been dedicated to biofuel as a fuel for engine alternatives. Biofuel is now primarily utilized in blends with fossil diesel. As a result, this study was focused on adding bioethanol and biodiesel to fossil diesel. Biodiesel was manufactured by transesterification from waste cooking oil, while bioethanol was made through banana fermentation. The physical properties such as density, kinematic viscosity, flashpoint, and cetane index of fossil diesel-biodiesel-bioethanol blends were compared with fossil diesel fuel in laboratory experiments. When added, bioethanol was found to degrade the physical properties of blended fuels substantially. The substitution of bioethanol for fossil diesel resulted in a significant reduction of hazardous emissions. The assessment of flue gas emissions indicated a considerable reduction in CO2, CO, hydrocarbon (HC) and NOx emissions.
