Emphasis on the biodiesel yield from the trans-esterification of waste oils should not only be of interest, but the production of high quality biodiesel should be of greater concern.Factors that determine quality of biodiesel are the production process(es) and biodiesel properties. High quality biodiesel must have cetane number (CN) that falls within the specifications of America Society for Testing and Materials (ASTM) and/or European Committee for Standardisation (EN). CN is a measure of auto ignition quality of a fuel; the higher the cetane number, the shorter the delay interval and the greater is its combustibility. In this research work, conditions for the production of high yields of biodiesel from the trans-esterification of Waste Soyabean Oil (WSO) and proposed model for the determination of biodiesel cetane number were established. The results of biodiesel yields obtained from the WSO trans-esterification showed that biodiesel yield was favoured at methanol/oil mole ratio of 6, NaOH catalyst concentration of 0.7 w/w oil, reaction temperature of 55 0C and reaction time of 90 minutes. Proposed biodiesel cetane number model obtained was validated. The statistical analysis yielded pearson correlation of 0.824 between the calculated cetane number using the proposed model and the experimentally reportedcetane number; p-value of 0.086. Interestingly, percentage average absolute deviation (% AAD) obtained for the calculated cetane numberand cetane number reported by Ramirez-Verduscoet. al. (2012), when compared to experimentally reported cetane number, generated the same result of 3.28 %.
