Jatropha Biodiesel Process
Transesterification is the process of converting the oil produced from vegetables into biodiesel. The process is less complex and it is quite easy. Transesterification is a chemical based production of biodiesel from jatropha oil.
In this process a complex fatty acids like triglyceride molecule is taken and it is neutralized. The glycerin is removed and an alcohol ester is created. This process is completed when methanol is mixed with sodium hydroxide. This result in the production of sodium methoxide which is then mixed with oil produced from the jatropha seeds. When the mixture settles glycerin is left at the bottom and the biodiesel (methyl esters) remains on the top. This methyl ester is washed and then filtered.
First jatropha oil is filtered to remove the solid particles present in it. Then it is heated to remove the water contents if any present in it.
Biodiesel is now been used as a diesel engine in number of agencies. The results are said to be comparable with petroleum in all the areas like power, efficiency, climbing, hauling etc.
To determine the amount of catalyst that is required for catalyst.
The accurate amount of potassium hydroxide is mixed with methanol till the methanol completely dissolves to get potassium methoxide.
In the winter season additional jatropha oil is heated and is mixed with the potassium methoxide.
The mixture is allowed to settle. In this process glycerin settles at the bottom and the biodiesel at the top. The glycerin is then removed and the biodiesel is washed and dried.
The biodiesel that is obtained is then checked for quality
In this process when methanol and potassium hydroxide to produce potassium methoxide which when mixed with oil produces strong polar bond. This breaks the fatty acids into glycerin and biodiesel (esters). These esters later become methyl esters. When the KOH is treated with ethanol it will form ethyl esters.
