Introduction:• Biodiesel is meant to be
used in standard diesel engines and is thus distinct from the vegetable and waste oils used to fuel converted diesel engines.
• Biodiesel is the methyl or ethyl ester of fatty acid.
• The 1’st use of peanut oil was made in 1895 by Dr. Rudolf Diesel.
• Following trees are used for biodiesel: Mahua,Nim,Jatropha,Karanji etc.
Manufacturing process
triglycerides diglycerides monoglycerides glycerol
Yielding one methyl ester molecule from glyceride at each step.
When methonol is used in the esterification,a catalyst & excess alcohal are used to increased rate of reaction & to the shift the equilibrium to the product side respectively.
Advantages:
Used in compression ignition engine.
No modification of diesel engine for biodiesel engine.
Biodiesel fuel is same to diesel fuel but is very eco-friendly.
Biodiesel is safe and non-polluting source of energy.
Availabilities and prices
Global biodiesel production reached 3.8 million tons in 2005.
Approximately 85% of biodiesel production came from the European union.
Biodiesel is now being produced locally in India for use in stationary engines and large or slow engines like those in trains, trucks and tractors.
Efforts are also on to use ethanol as a substitute for petrol.
Biodiesel is rapidly replacing both kerosene (which was used illegally and inefficiently) and diesel as a more efficient, cheap, and clean alternative for large engines.
Applications: Producing Hydrogen for Fuel-Cell Vehicles
Adding Lubricity to Diesel Fuel
Cleaning Up Tools and Grease
Cooking and Illumination
Heating Your Home
Generating Electricity
Cleaning Up Oil Spills
Removing Paint and Adhesives
Metal Working Lubricant
Hand Cleaner
Conclusion:Biodiesel is safe to handle because it is biodegradable and non-toxic.
Biodiesel reduces all the emission.
Biodiesel can be used alone or mixed in any amount with petroleum diesel fuel.
Biodiesel runs in any conventional, unmodified diesel engine.
Future scope of biodiesel
Biodiesel is a safe alternative fuel to replace traditional petroleum diesel. It has high-lubricity, is a clean-burning fuel and can be a fuel component for use in existing, unmodified diesel engines. Biodiesel acts like petroleum diesel, but produces less air pollution, comes from renewable sources, is biodegradable and is safer for the environment. In the United States today, biodiesel is typically produced from soybean or rapeseed oil or can be reprocessed from waste cooking oils
