Testing of n-butanol and eucalyptus essential oil as additivities of cottonseed biodiesel-diesel blends

Abstract

The B10 fuel blend in the presence (or absence) of n-butyl alcohol and eucalyptus essential oil additivities by the ASTM standards has been tested. As seen our results, these oxygenated compounds can be successfully used in B10 fuel blends as additives to improve exploitation properties. Methanol-based biodiesel has been synthesized by the transesterification reaction of technical cottonseed oil in the presence of potassium hydroxide, with a maximum yield of 64% at a molar ratio of oil to alcohol of 1:3, at 65°C. The oxidizing stability of the B10 fuel blends with (or without) additivities has been evaluated using the NMR spectroscopy method. Our experimental results demonstrated that investigated B10 fuel blend with oxygenated compounds has a high potential for diesel engines than B100 and petroleum diesel. The best results demonstrate the B10+n-Butanol fue
