3. • Need of Alternative Fuel
• Why Biodiesel? & What is it?

4. History
 Rudolf Diesel firstly tested the PEANUT OIL in
compression ignition in 1912

5.  Materials:-
• Cottonseed oil
• Ethanol
• Methanol
• Potassium hydroxide

6. • Shrub: 3 - 5 foot in height
• Draught resistant, perennial
• Starts producing after 5-6 months of plantation
• Seeds contain 50% oil (approx. 30% is extractable)
• Oil: non-edible
• Seed production: 0.8 to 5.2 tons per acre per annum (depending on soil &
Irrigation)
WHAT IS COTTON SEED ?

7.  Methods of Production :-
1.Thermal cracking or pyrolysis
2.Microemulsions
3.Transesterification

8. • Base Esterification
Triglycerides + Free Fatty Acids (<4%) + Alcohol ————>
Alkyl esters + glycerine Base
•Acid Esterification
Triglycerides + Free Fatty Acids (>4%) + Alcohol ————>
Alkyl esters + glycerine Acid

9.  Transesterification
 Separation of Byproduct
 Glycerine Refining
 Methanol Recovery
 Purification of Bio-Diesel

10. TRANESTERFICATION

11.  SEPARATION OF BY PRODUCT
Biodiesel and Glycerol are two major products that exists once transesterification
reaction is completed.
The Glycerol phase is much denser than biodiesel phase.
The Glycerol layer is drained out from separating funnel.

12.  Purification of Bio-Diesel
 Washing
 Dry Washing

14.  Less polluting than petroleum diesel
 Can use in existing diesel engine without any
modification
 Lack of Sulphur extends the life of catalytic
convertors

15.  1&1/2 times more expensive than petroleum based
fuel
 Can harm rubber hoses in some engines
 Due to no. Of processes cost of production is high

16.  Improved lubricity, , reduce global warming
 Contribute to rural development, allowing
additional income and job creation for developing
countries.
Diversifying the world’s fuel needs.
