COMPARATIVE STUDY OF BIOFUEL PRODUCTION FROM VARIOUS EDIBLE OILS

Biodiesel is a clean renewable fuel and hence has recently been considered as the best substitute for diesel. Chemically, biodiesel is a mixture of methyl ester with long chain fatty acids. It is produced from renewable biological sources such as vegetable oil and animal fats by simple Trans-esterification reaction. Among the energy resources biodiesel as a received more attention recently. In the present study, the potential impact of biodiesel production from edible oil such as sunflower oil and sesame oil was studied. The total acid number of sunflower oil was found to be 0.3 whereas TAN Number of sesame oil was recorded as 0.4. The results revealed that the biodiesel yield for sunflower oil was found to be 74.9% whereas in sesame oil the biodiesel yield was 71.4%. The effect of methanol to sunflower oil and sesame oil with different ration was studied indicated that three molar of triglycerides produce three molar of glycerol. The different ratio showed the concordant value was studied. Trans-esterification process consists of two step namely acid esterification and alkali esterification. Acid esterification was performed with H2SO4 and alkali Trans-esterification was performed with NaOH. In the present investigation purification performed in post treatment process. FTIR is useful for quantifying various conversion of Trans-esterification reaction. FTIR spectrum for sesame oil and sunflower oil produced biodiesel.
