| contents | <p>The gradual depletion of reserves from the petroleum resources and the impact of environmental pollution of increasing exhaust emissions from effluent activities, there is an urgent need to develop alternative energy resources, such as biodiesel fuel and biolubricants. This research study is aimed at sorting for alternative lubricant from Neem oil sourced from Neem plant (Azadirachta Indica). The analysis of the physical and chemical properties of Neem oil was carried out and compared with that of a conventional lubricant. Properties such as the free fatty acid, iodine value, viscosity, flash point, fire point, pour point and specific density were determined. The oil yield was 48.6%, iodine value of 56.47g/100g, acid value was 22.1 mg KOH/g, and free fatty acid was 11.11 mg KOH/g. The Neem oil flash and fire point obtained were 265°C and 289°C respectively and they were found to be in line with those obtained in both light duty oil (SAE 30) and heavy duty oil (SAE 40) with flash and fire point values of 243°C/290°C and 260°C/ 300°C, respectively. From the pour point values obtained, Neem oil which offers a poorer value of 250C as compared with that of light duty (SAE 30) and heavy duty oil (SAE 40) which has pour point values of 21°C and 9°C. The specific density of 0.910 for the Neem oil conforms to those of Light duty (SAE 30) and Heavy duty (SAE 40) with values of 0.895 and 0.889, respectively. It was also observed that the viscosity of the Neem oil decreased with increase in temperature. This was best with the light duty (SAE 30) which decreased from 104 CST to 12 CST while the Neem oil had viscosity of 109/22.6 cst at 40°C and 100°C. The heavy duty (SAE 40) had a viscosity of 126.4/9.1 CST at 40°C and at 100°C. Therefore Neem oil can successfully serve as a lubricant, based on the lubricant properties it displayed for both light automotive systems and heavy automotive system. But it would be advisable to use Neem oil in hotter regions of the world, and/or to use lubricant additives that would improve the pour point value of the Neem oil. </p> |
