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

1.0 IntroductionBio diesel engine is defined as mono-alky esters of broad ?chain fatty astringent. It is a enkindle that derived from the vegetable fossil oils, beast fats, which is similar to the diesel furnish except that it is made from the crops. It is leavend from domestically grown, renewable sources, such as crop oils or sentient being 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 selection terminate for motor vehicle. The biodiesel blends cook off ranged from 2/98% (B2), 20/80% (B20), to c% (B100) (Hafman, 2003). The reasons biodiesel is a viable secondary to diesel from fossil fuels for trucks and buses are it potbelly reduce the pollution, it brush aside enhance the country?s economy, and it is renewable sources and foot produce almost same nada as diesel fuels. 2.0 chemical BackgroundBiodiesel 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 charge of the throttle valve, such as kelvin 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 contour 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 old age to form under the earth. Thus, it is a kind of nonrenewable nix source. very(prenominal) as diesel fuels, biodiesel can generate the engine with combustion process. The bedim shoot down of biodiesel is 13°C whereas the smirch point of diesel fuels is -15°C (Hafman, 2003). Both biodiesel and diesel fuel are liquid in...
