Abstract
Biodiesel was successfully produced using palm kernel oil through transesterification. The effect of FeO, NaOH and NaOH/FeO catalyst in were studied in the production of the biodiesel. From the results, NaOH catalyst is more suitable for higher yield of biodiesel than its mixture (NaOH/FeO) and the least yield of biodiesel was obtained from using FeO from Palm Kernel Oil. Optimum of biodiesel yield of 68.75% was obtained using 1 M of NaOH as the catalyst. The palm kernel oil had free fatty acid value 3.935 mgKOH/g, Saponification value 242 mgKOH/g, Iodine value of 23 g/100 and acid value 7.85 mgKOH/g. The Palm Kernel Oil base biodiesel had properties such as specific gravity 0.860, kinematic viscosity 3.3 mm2/s, cetane number 45.5, cloud point 5 and acid value 0.5012 which agrees with biodiesel standard value.
