Abstract:
Growing concerns about environmental problems associated with fuels have engineered so much research into biofuels, such as biodiesel. However, continuous and large-scale production of biodiesel from edible oil could result in serious food security problems if cheap and viable alternatives are not made available. To solve this problem, oil was obtained from non-food/ underutilized seeds of palm kernel using Soxhlet apparatus. Physicochemical properties and fatty acids composition of these oils were determined using standard analytical and instrumental methods. Biodiesel was processed from these oils via sequential base (KOH) homogeneous catalysis. Fuel properties of biodiesel from the oil were determined using standard methods and the results obtained were compared with standards. Oil yields were found to be 37.6% for palm kernel seed respectively. Physicochemical properties of palm kernel oil respectively are: saponification value:(115.00)mg KOH/g, acid value(4.488)mgKOH/g, free fatty acid value (2.244)mg/KOH/viscosity:(29)mm2/s, moisture content: (0.46)%, peroxide value:(3.12)meqkg-1,refractive index:(1.455), specific gravity (0.899)g/cm. Fuel properties of biodiesel from palm kernel seed oil respectively are: Kinematic viscosity at 40oc: (nil) mm2/s, smoke point (100oc), flash point(90oc),fire point:(150oc),pour point(nil) and cloud point:(nil).The physicochemical properties of the biodiesel produced showed that the flash point, viscosity, density, ash content, percentage carbon content, specific gravity and the acid value fell within American Society for Testing and Materials (ASTM) specifications for biodiesel. Therefore, the biodiesel produced from the oil significantly met standard quality requirements.
