PASSIFLORA EDULIS SEED OIL METHYL ESTER AS A POTENTIAL SOURCE OF BIODIESEL

Abstract

The  fact that fossil energy reserves are limited coupled with the environmental pressure resulting from  their use has encouraged research on biodiesel and other biofuels. Biodiesel is a nontoxic, biodegradable and  renewable source of energy made by the transesterification of oils or fats with short chain alcohols. This study was focused on the use of Passiflora edulis  seed oil (Passion fruit).This oil was obtained from an industrial fruit juice processing waste. The oil was evaluated as a good potential feedstock for production of biodiesel. In this  study  Passiflora edulis seed oil was successfully transesterified using methanol and KOH as a catalyst.A biodiesel yield of 80% was obtained. The biodiesel had a viscosity of 4.60 mm2/s, acid value 0.45 mgKOH/g, density of 0.89g/ml, colour 1.60, water content 0.2%, copper strip corrosion-No tarnish, and flash point > 150 0C .The fuel parameters measured were within range according to the American Society for Testing and Materials (ASTM) and International Standards Organization (ISO) test methods apart from the percentage water content.
