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 oils, animal fats, which is similar to the diesel give the sack except that it is made from the crops. It is produced from domestically grown, renewable sources, such as crop oils or animal fats which atomic number 18 then chemically converted into biodiesel (Habmigren, 2003). Unlike diesel, biodiesel contains no petroleum products and free of sulphur compounds and aromatics (Habmigren, 2003). Until today, it is still the only alternative enkindle for motor vehicle. The biodiesel blends move over off ranged from 2/98% (B2), 20/80% (B20), to coke% (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 zipper as diesel fuels. 2.0 Chemical BackgroundBi odiesel comprises long-chain fatty acids with an intoxicant given up on it and produced finished the reaction of a vegetable oil with alcohol in the presence of the throttle valve, such as jet hydroxide or sodium hydroxide called transesterification (Hafman, 2003). The catalyst employ 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 t he petroleum which takes millions of histor! ic period to form under the earth. Thus, it is a kind of nonrenewable zilch source. very(prenominal) as diesel fuels, biodiesel can generate the engine by means of combustion process. The bedim point of biodiesel is 13°C whereas the dapple point of diesel fuels is -15°C (Hafman, 2003). Both biodiesel and diesel fuel are liquid in...
