Biodiesel is an alternative diesel fuel for diesel engines that is made from renewable biological sources like vegetable oils, animal fats, and microalgae. Since its main feedstock is a vegetable oil or animal fat, biodiesel is generally considered to be renewable. There are four primary ways known to make biodiesel – (1) direct use and blending, (2) microemulsions, (3) thermal cracking and (4) transesterification. Although the main use is the transesterification of vegetable oils and animal fats, all four ways are going to be discussed through the research. Even though hundred years ago, Rudolf Diesel tested vegetable oil as fuel for his engine, with the presence of cheap petroleum, petroleum fractions were the fuel that took the market. By

For this reaction catalysts are strong bases like NaOH, KOH. The reaction results in methyl esters which is known as biodiesel worldwide.
Before turning into the production of biodiesel, we should know about pros and cons of biodiesel over petroleum.
Advantages:
Biodiesel fuel is a renewable energy source unlike petroleum.
An excessive production of soybeans in the world makes it an economic way to utilize the manufacturing of biodiesel.
it is environmental-friendly; that, is it is less polluting than petroleum.
The lack of sulfur in 100% biodiesel increases the lifetime engine..
It could also be utilized as a blending for other energy resources and oil.
It has very high lubricating property
In comparison with regular oil, it has lower emission of carbon monoxide, unburned hydrocarbons, and particulate …show more content…
It was even claimed that biodiesel could be used as a primary where petroleum being an alternative fuels. So there were many conferences about biodiesel costs and production which results in biodiesel usage as a blending. Biodiesel was blended in range of 10% to 50%; nevertheless, it was not appropriate to substitute 100% of fuel with biodiesel. According to scientists problems appear only after the engine has been operating on vegetable oils for longer periods of time. The problems include coking and trumpet formation on the injectors which lead to absence of the fuel atomization, carbon deposits, oil ring clinging and thickening of the lubricating oil as a result of contamination by the vegetable oils. However some of this problems is disappearing when biodiesel blend is below 50%. Although today in some countries this method is active, direct use of vegetable oils and/or the use of blends of the oils has generally been considered to be not satisfactory and practical for diesel engines. The high viscosity and acid composition are the main reason why we do not use this
