This study investigated the effects of Al2O3 nanoparticles on the physical and thermal properties of trans-esterified Sennatora oil, aiming to enhance its combustion efficiency. The study also evaluates the oil’s physical and thermal properties, both with and without the addition of Al2O3 nanoparticles. The methods adopted in the study include extraction of oil from Sennatora seeds obtained from Kano, Northwest Nigeria, its purification and the synthesis of trans-esterified Sennatora oil, and its characterization using Scanning Electron Microscopy (SEM) and Fourier Transform Infrared Spectroscopy (FTIR). The composition of free fatty acids (FFAs) was investigated using Gas chromatography Mass Spectroscopy (GCMS). The results showed an acid value of 3.74mgKOH/g and pH of 5.8 for the crude oil and 0.45mgKOH/g and pH of 6.5 for the esterified oil. The addition of Al2O3 nanoparticles has increased pH to 6.9 while the flash point of the oil was observed to have decreased from 2250C to 2180C while the calorific value increased from 17.68MJ/kg to 19.45MJ/g. The major fatty acids contained oleic acid (30.73%), linoleic acid (23.41%), stearic acid (6.52%), and palmitic acid (11.54%). This work underscores the importance of exploring alternative bio-resources like Sennatora to address global energy and environmental challenges effectively.
