Abstract
Biodiesel has gained support and recognition as a fuel to replace and blending agent with fossil diesel. In search of non-edible seed oil feed stock than can be used for biodiesel production using sodium hydroxide (NaOH) as homogeneous catalyst. An investigation was carried out with P. macrophylum seed oil present in Bida, Niger State. The leaf of this seed oil is used for medicinal purpose by Bida people treatment of scorpion and snake bite. The seed yielded 40.0% oil by solvent extraction. The oil was transesterified with methanol using homogeneous catalyst sodium hydroxide (NaOH) with optimize parameters; methanol to oil ratio (6:1), temperature (55 ℃), catalyst concentration (1.6 wt%), reaction time (60 min), and agitation speed (300 rpm). The cloud point and pour point of the produced biodiesel falls between (-11.2 and -4.5) which is within ASTM and EU standards. The biodiesel yield of 74.2, 75.3, 80.2 and 83.2 were also recorded with NaOH catalyst which fasting transesterification reaction than heterogeneous catalyst (CaO). P. macrophylum oil can be a potential feedstock for biodiesel production. Since the oil is non-edible and it will not interfere with food chain.
