Is Biodiesel a Viable Alternative To Diesel From Fossil Fuels For Trucks And Buses?

1.0 IntroductionBiodiesel is defined as mono-alky esters of long ?chain fatty acid. It is a enkindle that derived from the vegetable oil colours, animal fats, which is similar to the diesel burn except that it is made from the crops. It is produced from domestically grown, renewable sources, such as crop oils or animal fats which are then chemically converted into biodiesel (Habmigren, 2003). Unlike diesel, biodiesel contains no petroleum products and free of south compounds and aromatics (Habmigren, 2003). Until today, it is still the only alternative elicit for motor vehicle. The biodiesel blends open off ranged from 2/98% (B2), 20/80% (B20), to light speed% (B100) (Hafman, 2003). The reasons biodiesel is a viable alternative to diesel from fossil fuels for trucks and buses are it potbelly reduce the pollution, it can enhance the country?s economy, and it is renewable sources and can produce almost same button as diesel fuels. 2.0 Chemical BackgroundBiodiesel comprises long-chain fatty acids with an intoxicant accustomed on it and produced finished the reaction of a vegetable oil with alcohol in the presence of the atom smasher, such as one thousand hydroxide or sodium hydroxide called transesterification (Hafman, 2003). The catalyst use to hydrolysis the triglyceride, and alcohols trustingness with the fatty acid to produce biodiesel (Gorham, 2006).

After a round reaction, the glycerol and ester constellation two liquid layers and catalyst is distant for reuse. (Vegetable oil) + (Alcohol) ? (Glycerol) +(Methyl Ester)On the other hand, diesel is made from the petroleum which takes millions of years to form unde! r the earth. Thus, it is a kind of nonrenewable readiness source. very(prenominal) as diesel fuels, biodiesel can generate the engine through combustion process. The bedim point of biodiesel is 13°C whereas the sully point of diesel fuels is -15°C (Hafman, 2003). Both biodiesel and diesel fuel are liquid in...
