  • What is Biodiesel ?

    Biodiesel refers to a non-petroleum-based diesel fuel consisting of short chain alkyl (methyl or ethyl) esters, made by Transesterfication of vegetable oil or animal fat , which can be used (alone, or blended with conventional petro-diesel) in unmodified diesel-engine vehicles.

    "Biodiesel" is standardized as mono-alkyl ester.

  • History of Vegetable Oil Based Fuels1900 - Rudolph Diesel debuted the first diesel engine running on peanut oil at the Worlds Exhibition in ParisHe likely used peanut oil at the request of the French Government, who were interested in its use in their African coloniesAfter Diesels mysterious death in 1913, development focused on the use of petroleum-based fuels

    The use of vegetable oils as engine fuels may seem insignificant today but the such oils may become, in the course of time, as important as petroleum and the coal tar products of the present time.-Rudolph Diesel, 1912

  • Globally, transportation accounts for 25% of energy demand and nearly 62% of oil consumed. The generation of electricity is the single largest use of fuel in the world.More than 60 % of power generated comes from fossil fuels.

  • This is the process of separating the fatty acids from their glycerol backbone to form biodiesel and glycerine.

    Transesterification is the reversible reaction of oil with an alcohol (methanol or ethanol) to form fatty acid alkyl esters and glycerol.

    The vegetable oil molecules is reduced to about 1/3rd its original size, lowering its viscosity, making it similar to diesel.


  • Transesterification reaction

  • Washing biodiesel with water is the oldest and most common method of cleaning biodiesel. Methanol is a solvent, it captures soap and other impurities and holds them dissolved in the biodiesel. Water soaks up that methanol,releasing impurities to be washed away with water.

    Type of Water washing used :

    Water Washing

    Air / Bubble Washing

    Washing and Drying

  • Railway usage The British businessman RichardBranson's Virgin Voyager train number220007 Thames Voyager,billed as theworld's first "biodiesel train".

  • AIRCRAFTFeb 2009 The first flight by a commercial airline to be partly powered by biofuels and billed asheralding a eco-friendlier and cheaper era ofairline travel took place

  • Indian InitiativesNational Mission on Biodiesel has been launched by GOIState Governments designated special authorities/bodies to manageMinistry of Petroleum and Natural Gas notified biodiesel purchase policyGovernment Institutes are working on technology and promotionPublic and private sectors are working on processing and end use

  • Some more practicalitiesThe former President of India, Late Dr. Abdul Kalam, is one of the strong advocaters of Jatropha cultivation for production of bio-diesel.

    The State Bank of India provided a boost to the cultivation of Jatropha in India by signing a MoU with D1 Mohan, a joint venture of D1 Oils plc, to give loans to the tune of 1.3 billion rupees to local farmers in India.

    Older diesel Mercedes are popular for running on biodiesel

  • Biodiesel : First trial run on trainFirst successful trial run of a superfast passenger train was conducted on Dec 31, 2009Delhi - Amritsar Shatabdi Express used 5% of biodiesel fuel.Railway annual fuel bill = Rs 3400 crore (for Diesel)10% mixture with Diesel = reduced (Rs.300-400 crore / annum)5% substitution is accepted.

  • Andhra Pradesh has entered into a formal agreement with Reliance Industries for Jatropha planting. The company has selected 200acres (0.81km2) of land at Kakinada to grow Jatropha for high quality bio-diesel fuel.

    Chhattisgarh has decided to plant 160 million saplings of Jatropha in all its 16 districts during 2006 with the aim of becoming a bio-fuel self-reliant state by 2015.

  • On Nov 2005, the Maharashtra Government aimed to cultivate Jatropha on 600km in the state.September 2007-Hindustan Petroleum Corporation Limited(HPCL) joined hands with the Maharashtra State Farming Corporation Ltd(MSFCL) for a Jatropha seed-based bio-diesel venture. Jatropha plant would be grown on 500 acres (2km) in Nashik and Aurangabad.

  • Bio diesel is environmental friendly. It can help reduce dependency on foreign oil. It helps to lubricate the engine itself, decreasing engine wear. It offers similar power to diesel fuel. It is safer than conventional diesel. It can be made from waste products.It can be made at home easily.

  • Its storage for long period is not suitable for engine operation.It becomes gel in cold weather.It has water content. (Hygroscopic)It has higher (10%) Nox emissions.It decreases horsepower. (25%)

  • By mixing of 20 per cent biodiesel with diesel will help India to save 7.3x106 tones of diesel per year.

    In India about 33 million hectares of wasteland is available and can effectively be used for cultivation of jatropha plants.

    It offers business possibility to agricultural enterprises and rural employment. Biodiesel is least-cost-strategy to comply with state and federal regulations. Use of biodiesel does not require major engine modifications. The only thing that changes is air quality.Biodiesel has positive attributes such as increased cetane, high fuel lubricity & high oxygen content.

  • Biodiesel reduces by as much as 65 % the emission of small particles of solid combustion products.

    The ozone (smog) forming potentials of hydrocarbons is less than diesel fuel.

    Sulfur emissions are essentially eliminated with pure biodiesel .

    Biodiesel contain no petroleum, but can be blended with conventional diesel fuel.These fuel can be used in any diesel engine without any modification.Biodiesel is degradable , non toxic and free from sulphur and lead.
