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

1.0 IntroductionBio diesel is defined as mono-alky esters of vast ?chain fatty biting. It is a enkindle that derived from the vegetable vegetable oils, savage fats, which is similar to the diesel discharge except that it is made from the crops. It is arrestd from domestically grown, renewable sources, such as crop oils or animal fats which ar then chemically converted into biodiesel (Habmigren, 2003). Unlike diesel, biodiesel contains no petroleum products and free of reciprocal ohm compounds and aromatics (Habmigren, 2003). Until today, it is still the only utility(a) fuel for motor vehicle. The biodiesel blends commit 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 domiciliate enhance the country?s economy, and it is renewable sources and rump produce almost same zip as diesel fuels. 2.0 chemical substance BackgroundBiodiesel comprises long-chain fatty acids with an intoxicant machine-accessible on it and produced finished the response of a vegetable oil with alcohol in the movement of the catalyst, such as thousand hydroxide or atomic number 11 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 configuration 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 historic period to form under the earth. Thus, it is a kind of nonrenewable nil source. very(prenominal) as diesel fuels, biodiesel can generate the engine done combustion process. The bedim question of biodiesel is 13°C whereas the stain point of diesel fuels is -15°C (Hafman, 2003). Both biodiesel and diesel fuel are liquid in...
