1. Presented By, R.Mathankumar 2022048022 BIO-DIESEL PRODUCTION

2. Biodiesel is produced from vegetable oils or animal fats and an alcohol, through a transesterification reaction. Stages of Transesterification: Treatment of raw material Alcohol catalyst mixing Chemical reaction Separation of reaction products Purification of reaction products Biodiesel Production Process

3. Transesterification is a chemical reaction where triglyceride is reacted with alcohol in the presence of catalyst to produce alkyl esters. Transesterification Process Vegetable Oil Biodiesel Fatty Acid Alcohol Glycerin

4. Biodiesel Production Process

5. Plants are able to produce seeds between 1 and 5 years depending on soil fertility and rainfall, and continue to produce seeds for more than 20 years. Seed yield under cultivation can range from 1,500 to 2,000 kg per hectare. The seeds contain average 34.4% oil by weight that can be processed to produce a high quality biodiesel fuel. Jatropha - Suited Raw Material

6. The yield of biodiesel per hectare for Jatropha is more than four times as much fuel per hectare as soybean, and up to ten times to that of corn.

7. Blending is the process of mixing of biodiesel fuel with petroleum-based diesel fuel , designated as BXX. where XX is the volume percent of biodiesel. Blending of Biodiesel

8. Disadvantages of Biodiesel Slightly higher fuel consumption due to the lower calorific value of biodiesel. Slightly higher nitrous oxide ( NOx ) emissions than diesel fuel. Higher freezing point than diesel fuel. This may be inconvenient in cold climates. It is less stable than diesel fuel, and therefore long-term storage (more than six months) of biodiesel is not recommended.
