The present-day internal combustion engines are operating essentially on petroleum-based fuels, which are non-renewable in nature and lead to depletion in short period due to its indiscriminate use in different fuels. Renewable agriculture based, non-edible oils like pongamia, mahua (Maduca Indica), neem, jatropha oils etc. can be used as an alternative fuel in CI engines. Biodiesel production from Mahua seed was experimentally investigated in the present study. Expeller method was employed to extract mahua oil from its seed and was subjected to two stage transesterifications due to the presence of more than 18% of free fatty acid content. In the primary stage, the FFA content was reduced to less than 2% by acid esterification using concentrated H2SO4and methanol and followed by base catalyzed transesterification to convert the mahua oil into biodiesel. The properties like density, viscosity, and Calorific value, flash and fire point were analyzed and compared with another prominent biodiesel.
