Mechanically

Chemically

Enzymatically


It is also used as:

Jet fuel

Light hydrocarbon fuel

Myanmar biodiesel

Jatropha Seeds

Biodiesel extracted from jatropha curcas is called as Jatropoha Methyl Ester. The seed of physic nut jatropha has insecticides and fungicides properties in them. The latex of the plant contains alkaloid which has anti cancerous property.


High quality jatropha seeds have the following yield during their yield.

  Year 1 - 3kg/tree

  Year 2 - 6kg/tree

  Year 3 - 9kg/tree

  Year 4 - 10-12kg/tree

  Year 5 - 10-15kg/tree


Jatropha seeds can produce 60% oil depending on the following factors:

  Yielding capacity of the plant

  Advanced pruning techniques

  Soil moisture level

  Soil nutrient level

  Application of fertilizers

  Stage of ripening

Jatropha oil is also a kind of vegetable oil that is produced from the seeds of jatropha that has the capacity to grow in marginal and common lands. Below are some of the benefits of jatropha oil.


Used as a alternative for diesel as a renewable source.

Have the properties that are similar to diesel fuel.

It is a oxygenated fuel and is also a eco friendly.

Contains less sulphur.

Can be used in the diesel engine with little modification in the engines.

Emission of exhaust gas is reduced.

Use as biodiesel:

In order to meet the decreasing foreign exchange reserves it is essential to find a renewable resource that is better for this problem. So to meet the growing demand non-edible seeds from the jatropha plant has a potential effect on this increasing requirement. The oil that is extracted from the jatropha plant is used as a substitute for diesel in many parts of the world. The biodiesel that is prepared from the jatropha oil is more economical than any other diesel.


Transesterification is the process that is used to produce biodiesel from jatropha oil. In this process triglycerides is converted into methyl esters. And the oil is mixed with alcohol and catalyst and is kept at the reaction temperature for a specific duration of time under agitation. Then it is send to the settling tank. At last the ester is collected and washed to get pure biodiesel.
