Abstract

INFLUENCE OF REACTION TIME IN THE PRODUCTION OF BIODIESEL FROM PALM OIL MILL EFFLUENT (POME)

ABSTRACT

The reaction time affects the conversion efficiency of the trans-esterification process of converting oil to biodiesel. In this study, the effect of reaction time at different time interval on biodiesel yield was examined. Bio-oil was extracted from palm oil mill effluent (POME) using soxhlet extraction apparatus. The feed oil to solvent ratio used was 3:1. N-hexane reagent of 80 ml was added to 240 ml of feed oil collected from a local palm oil mill in Ogbomoso and heated for 60 minutes to a temperature of 75oC. Biodiesel was produced from the trans-esterification reaction of 150 ml bio-oil with 0.046 g of potassium hydroxide as catalyst and 25 ml of ethanol which serves as the limiting reagent at a reaction temperature of 65oC. The reaction time was varied over a range of 60, 90, 120 and 150 minutes. The results indicated that optimal reaction time was 120 minutes with maximum percentage yield of 80%. The properties of biodiesel produced in this study meet the specification of ASTM and EN standards. This study has therefore indicated the influence of reaction time to achieve highest production of biodiesel from POME.
