Abstract

Oil was extracted from Lophira lanceolata seeds and some physicochemical properties were examined. The oil yield is promising. Methyl ester derivative which exhibited better fuel properties was produced from the oil. The refractive index, free fatty acid, kinematic viscosity, saponification and iodine values were determined and discussed in relationship to its applications. The energy density compared favourably with those of other seed oils and commercial grade diesel. The waste shells were also utilized for the production of biogas with potentials as energy resource that can be stored and used. The residue left behind possessed bio-fertilizer value showing the presence of N, P, K, Ca, Mg. Hence, L. lanceolata has potentials of a renewable energy resource.

Key words: Lophira lanceolata, methyl ester, refractive index, biogas, bio-fertilizer.
