Assessment of Oxidation Stability of Oils for Biodiesel Production (original) (raw)

As the fossil fuels are depleting day by day, so there is a need to reach for an alternative fuel to meet the energy demand of the world. The various oil sources classified as edible and non edible the edible sources like groundnut, peanut etc are primarily used to meet the food requirement but the excess supplies can be converted to biodiesel. Since India is already importing 70% of the edible oils and therefore the diversion of edible oil for biodiesel production is not possible. The option rests only on the nonedible oils for conversion to biodiesel. The main quality problem with biodiesel is its oxidation stability that plays an important role in determining the quality. Which is the resistance of oil/fats/biodiesel to degradation through oxidation with air? The rapidity of oxidation depends on the degree of unsaturation, the presence of antioxidants, and prior storage conditions. This auto oxidation caused by contact with air during long term storage presents a legitimate conce...
