Abstract

Methanolic transesterification of Croton megalocarpus seed oil to produce biodiesel was investigated using Immobilized Candida antarctica lipase as a catalyst. The reactions were optimized by varying the temperature, amount of methanol and the weight of lipase. The transesterification process yielded 98.71 % biodiesel conversion at optimal conditions of 30 % enzyme (m/m), 50 0 C reaction temperature and oil to alcohol molar ratio of 1:4. Biodiesel from this process had a remarkably high acid value. All the other fuel properties measured were within the range stipulated in the American Society for Testing and Materials (ASTM) and International Standards Organization (ISO) standards.
