Abstract : The production of biodiesel from edible oils and industrial catalysts increases its production cost and makes its price higher than fossil diesel. The fatty waste generated by slaughtering industries pollutes the environment and could be converted into bioenergy by various processes. Potash salt is extracted from sorghum and formulated to serve as a biocatalyst in the transesterification process of Bos Taurus Zebus tallow into biodiesel. The characterization of tallow, biocatalyst and biodiesel is carried out. The tallow has a viscosity, acidity index, density of 7.2 mm 2 /s, 5.3 mg KOH /g and 911.3 Kg/m3 respectively. The extracted potash has a potassium content of 58.3% and a pH of 10.7, characterizing the basicity of the salt. The biodiesel production yield under the constraint of a full factorial experimental design is 96.53%. The major oleic ester in the composition of the derived biodiesel is 19.65%. The viscosity and density are 5.45 mm 2 /s and 874 kg/m3 at 40°C, respectively. The cetane number is 56.7, which is higher than that of regular diesel. The obtained biodiesel can be used as an additive to fossil fuels or to power compression ignition engines.

Keywords : Biodiesel; Esterification; Full Factorial Design; Transesterification; Potash Salt.
