Improvement of Biodiesel from Marotti Oil

H L KULKARNI

Abstract


Marotti oil, is an important non edible oils obtainable in India, was esterified to produce biodiesel. The optimized process for biodiesel development from marotti oil involves a two stage process. The free fatty acid content of the selected oil is 4.5% which requires the two stage process. The free fatty acid content is decreased to less than 3% by the acid esterification method and biodiesel is produced in the alkaline transesterification process. The optimum conditions of the biodiesel production were established by studying the effects of several parameters like catalyst concentration, reaction temperature, methanol to oil ratio and reaction time. A conversion effectiveness of 92% was achieved and the various properties are found to be in the limits specified by biodiesel standards.
