- ItemCHARACTERIZATION AND DETERMINATION OF OPTIMUM BLENDING RATIO OF BLENDED WATERMELON SEED OIL(NIGERIAL JOURNAL OF ENGINEERING AND APPLIED SCIENCES (NJEAS), 2024) Busari R. A.; Adebayo K. R.; Alabi K. P.Watermelon fruit contains large amounts of seeds, which are underutilized in Nigeria. The seeds contain about 22% oil, which can be used as vegetable oil or as feedstock for biodiesel to power agricultural machineries. This study explored the physicochemical properties of watermelon biodiesel, crucial for understanding its suitability for various applications. The research demonstrated that watermelon biodiesel meets specified standards such as ASTM D-6751 and EN-14214, ensuring its viability for widespread use. Post-transesterification, the viscosity of raw watermelon oil decreases, though it remains notably higher than that of conventional diesel fuel. Moreover, watermelon biodiesel blends ranging from B5 to B25 comply with diverse specification standards, further validating its utility. Despite reductions in density, specific gravity, and flash point after transesterification, these values remain higher compared to diesel fuel. The study developed regression equations to forecast properties at varying blending ratios, indicating strong correlations between biodiesel properties and blending percentages. Notably, the derived equations exhibited high coefficient of regression values (0.8389 for density, 0.9317 for kinematic viscosity, 0.9669 for flash point, 0.9702 for specific gravity, and 0.9025 for calorific value), highlighting the reliability of predictions. Based on standard compliance considerations, a blending ratio of up to 25% was recommended as optimal for achieving desired properties in watermelon biodiesel blends.
- ItemEFFECT OF PROCESSING PARAMETERS ON SOLVENT OIL EXPRESSION FROM LOOFAH SEEDS (LUFFA CYLINDRICA L.) USING RESPONSE SURFACE METHODOLOGY(Published by Faculty of Engineering, University of Maiduguri, Maiduguri, Nigeria, 2019) Akpenpuun T. D; Busari R. A.; Iyanda M. O.Luffah cylindrica plant grows in the wild, around uncompleted buildings and fenced walls. The percentage oil composition of its seeds is about 30% oil. The research focused was the extraction oil from loofah seed using a solvent extraction methodology. Optimum conditions for oil extraction were determined using Response Surface Methodology of Central Composite Rotatable Design. A total of 20 experimental runs were used to investigate the optimum condition considering three independent variables at five levels each: extraction temperature (55, 60, 65, 60, 75ºC), seed/solvent ratio (0.04, 0.05, 0.06, 0.07, 0.08 g/ml) and extraction time (4, 5, 6, 7, 8 hr.). An empirical model equation that could be used to forecast oil yield as a function of the independent variables was developed. The optimum oil yield obtained was 27.43% at the extraction temperature (74.05ºC), seed/solvent ratio (0.05 g/ml) and extraction time (5.35hr). The analysis of variance showed that extraction temperature and time had significant effect on oil yield (p = 0.05). The interaction of the independent variables with oil yield gave R2 and R2 adj. values of 0.98 and 0.93, respectively. The result showed that the selected independent variables had a significant effect on oil yield, thus an optimum condition was established.
