Biodiesel is made from the process called “esterificiation” in which industrial alcohol (ethanol or methanol) and a catalyst (substance that enables a chemical reaction) use to convert the base oil into biodiesel. In the initial stage of this process, biodiesel is known as “neat biodiesel” or B100. One of the advantages of biodiesel is that it can be blended with conventional diesel. Almost all the diesel engines can run on biodiesel without needing any special additional equipment.
Rudolf Diesel was the one who demonstrated a Diesel engine running on peanut oil built by the French Otto Company at the World Fair in Paris, France in 1900. Though it powered by peanut, that was not biodiesel. Lots of researches were done on biodiesel all through this time. But in 1977, Expedito Parente, a Brazilian scientist produced biodiesel using transesterification with ethanol. In 1979, South Africa initiated the research into the use of transesterified sunflower oil and refining it to diesel fuel standards.
By 1983, the process for producing fuel-quality, engine-tested biodiesel was completed and published internationally. Large number of Bio diesel plants were opened in many countries including Germany, Sweden and Czech Republic in the 90s.
It is proved that Vehicles have similar horsepower and torque as conventional diesel when running on biodiesel. The price of biodiesel blends can vary depending on geographic area, base material (corn, soybeans, etc.), and supplier. Biodiesel has many advantages over the conventional diesel. Biodiesel is harmless, eco-friendly and biodegradable. The biodiesel has a very high cetane number and this high cetane numbers of biodiesel assists to easy cold starting and low idle noise.
Other major advantage is that the life of diesel engines is extended with the biodiesel, because it is more lubricating and additionally, power output is comparatively unaltered by biodiesel. Finally, the eco-friendly biodiesel fuel substitutes the exhaust odor of petroleum diesel with a more pleasant smell of popcorn or French fries.
Now, biodiesel is slowly becoming available in almost all countries. In United States approximately 800 locations are serving the various blends of biodiesel. Price of the biodiesel is also low compared to other conventional petroleum products. As it is the eco friendly alternative fuel, it would be our main source of fuel in the near future.
Clifton is a qualified mechanical engineer committed to finding alternative fuel sources that can be incorporated into everyday life. Alternative energy sources with reduced environmental effects will need to be discovered and used in order to generate the power requirements our lifestyle currently demands.
