3. Introduction
-Biodiesel
-Historical background- Patrick duffy 1853
-International Biodiesel Day- 10 Aug

4. Sources
- Vegetable oil
- Animal fat
- Jathropa ( contains 40% of oil)
- Soybeans
- canola / Rapeseed
- Camelina
- Sun flower oil
- Algae & Oil palm

5. Transesterification

R1, R2, and R3 are fatty acid alkyl groups
(could be different, or the same), and depend
on the type of oil. The fatty acids involved
determine the final properties of the biodiesel
(cetane number, cold flow properties, etc.)

6. Simple Approach-HowBioDisel
Can Made

8. Properties of Biodiesel
- Calorific value- 37.27 MJ/kg
- Color- Varies from Golden to Dark Brown
- Flash point- >130 °C, >266 °F
- density ~ 0.88 g/cm³
- High boiling point
- Low vapor pressure
- Immiscible with water
- No sulphur content
- High Cetane number

9. Material compatibility
- Plastics- HDPE is compatible, PVC is not
compatible, Polysrtyne get dissolves
- Metals: Biodiesel has an effect on copper-
based materials (e.g. brass), and it also affects
zinc, tin, lead, and cast iron. Stainless steels
(316 and 304) and aluminum are unaffected
- Rubber: Biodiesel also affects some types of
natural rubbers

10. Applications
- Vehicular use and Manufacturer acceptance
- Railway uses
- Aircraft uses
- As a heating oil
- For cleaning oil spill
- In generators

11. Benefits of Biodiesel
- Clean fuel that is an excellent alternative to
petroleum.
- Hundred percent renewable
- A positive impact on the environment
- No or little vehicle modifications or special
fuelling equipment
- With a high flash point, biodiesel is safer to
handle and store
- provides excellent lubricity to the fuel
injection system

12. - Provides significantly reduced emissions of carbon
monoxide, particulate matter, unburned
hydrocarbons, and sulphates
- Helps reduce the risk of global warming by
reducing net carbon emissions to the atmosphere
- Being derived from vegetable oils, biodiesel is
naturally non-toxic
- In both soil and water, biodiesel degraded at a rate
4 times faster than regular diesel fuel
- can be made from different oils and fats, waste
products. Waste cooking oil, animal feed mixtures
can be converted to high quality biodiesel

13. Disadvantages
• Lower Energy Content
• Less energy produces , but have also higher cetane ,
lubricity, etc.
• Poor cold weather performance
• This can be mitigated by blending with diesel fuel or with
additives, or using low gel point feedstocks such as
rapeseed/canola.
• Stability Concerns
• Biodiesel is less oxidatively stable than petroleum diesel
fuel. Old fuel can become acidic and form sediments and
varnish. Additives can prevent this.
• Scalability
• Current feedstock technology limits large scalability

14. Biodiesel Emissions

15. Conclusion
- By knowing about the biodiesel as a fuel we came to
know that, biodiesel is the today's best alternatives
for the fossils fuels like diesel and gasoline.
- It can be used in vehicles with some modification in
the vehicle
- Production of biodiesel is easy as compared to the
fossil fuels, also it is easy to handle and less pollutant
than that of fossil fuels.
- Biodiesel is environment friendly and human friendly
