Full Text	This invention relates to a process of extracting Jatropha Curcas oil from Jatropha seeds for use in diesel engines. BACKGROUND Diesel engines are being driven by diesel, which has carbon hydrogen ratio 6.5. Accordingly, there is lot of pollution in the city generated by diesel vehicles or diesel engine. The object of this invention is to obtain green diesel produced from Jatropha seeds, which will have much less pollution generated with diesel engine or vehicles. To achieve the said objective, this invention provides a process for extracting Jatropha Curcas oil from Jatropha seeds comprising: removing pulp from the seeds, extracting oil from said seeds using an expeller, separating oil containing 35% carbon by filter press to remove sludge, decreasing carbon percentage from 35% to 10-20% by refining said filtered oil by a micro-filter of 250-500 mesh, and further filtering the above oil through a 50-70 mesh micro-filter to remove sludge and to better combustion value of the oil. The micro-filters used are 400-450 mesh and 60 mesh respectively. The above oil was tested by Hi-tech Research Centre Laboratory, New Delhi and the test results are given in the following table: (Table Removed) No. of Parameter tested: 11 only Remarks: 1) The product as received is without any sediment, 2) On heating the product beyond the flash point, the product burns in natural flame, 3) Low calculated cetane number of the product indicates that the product is highly aromatic in nature. 4) This J. Oil of vegetabel plabt origin is likely to be eco-friendly and non- polluting. It may be seen from the table that the carbon contents and the sulphur, which produce heavy pollution is much less in the oil so produced. It is for this reason, e call this oil as green oil, which is eco-friendly, non-polluting and originates from plant. The invention will now be described with reference to the following example: Example: Take 100 Kg of dry seeds. Remove pulp from the seeds. Extract oil from said seeds by using an expeller. Separate oil from filter press to remove sludge. Filter the said oil through micro-filters 400 mesh and 60 mesh respectively to decrease the carbon percentage from said filtered oil. It was found that 100 Kg. dry seeds produced 35 Kg crude oil with better combustion value. The product as received is without any sediment. On heating the product beyond the flash point the product burns in natural flame. Low calculated cetane number of the product indicates that the product is highly aromatic in nature. The oil produced is eco-friendly and non-polluting. I claim: 1. A process for extracting Jatropha Curcas oil from Jatropha seeds comprising: removing pulp from the seeds, extracting oil from said seeds using an expeller, separating oil containing 35% carbon by filter press to remove sludge, decreasing carbon percentage from 35% to 10-20% by refining said filtered oil by a micro-filter of 250-500 mesh, and further filtering the above oil through a 50-70 mesh micro-filter to remove sludge and to get better combustion value of the oil. 2. A process as claimed in claim 1 wherein the micro-filters used is 400-450 mesh and 60 mesh respectively. 3. A process for extracting Jatropha Curcas oil from Jatropha seeds substantially as herein described with reference to the foregoing example.

This invention relates to a process of extracting Jatropha Curcas oil from Jatropha seeds for use in diesel engines.
BACKGROUND
Diesel engines are being driven by diesel, which has carbon hydrogen ratio 6.5. Accordingly, there is lot of pollution in the city generated by diesel vehicles or diesel engine.
The object of this invention is to obtain green diesel produced from Jatropha seeds, which will have much less pollution generated with diesel engine or vehicles.
To achieve the said objective, this invention provides a process for extracting Jatropha Curcas oil from Jatropha seeds comprising:
removing pulp from the seeds,
extracting oil from said seeds using an expeller,
separating oil containing 35% carbon by filter press to remove
sludge,
decreasing carbon percentage from 35% to 10-20% by refining said
filtered oil by a micro-filter of 250-500 mesh, and
further filtering the above oil through a 50-70 mesh micro-filter to
remove sludge and to better combustion value of the oil.
The micro-filters used are 400-450 mesh and 60 mesh respectively.
The above oil was tested by Hi-tech Research Centre Laboratory, New Delhi and the test results are given in the following table:
(Table Removed)
No. of Parameter tested: 11 only
Remarks:
1) The product as received is without any sediment,
2) On heating the product beyond the flash point, the product burns in
natural flame,
3) Low calculated cetane number of the product indicates that the product is
highly aromatic in nature.
4) This J. Oil of vegetabel plabt origin is likely to be eco-friendly and non-
polluting.
It may be seen from the table that the carbon contents and the sulphur, which produce heavy pollution is much less in the oil so produced. It is for this reason,
e call this oil as green oil, which is eco-friendly, non-polluting and originates from plant.
The invention will now be described with reference to the following example:
Example:
Take 100 Kg of dry seeds. Remove pulp from the seeds. Extract oil from said seeds by using an expeller. Separate oil from filter press to remove sludge. Filter the said oil through micro-filters 400 mesh and 60 mesh respectively to decrease the carbon percentage from said filtered oil. It was found that 100 Kg. dry seeds produced 35 Kg crude oil with better combustion value.
The product as received is without any sediment. On heating the product beyond the flash point the product burns in natural flame. Low calculated cetane number of the product indicates that the product is highly aromatic in nature. The oil produced is eco-friendly and non-polluting.

I claim:
1. A process for extracting Jatropha Curcas oil from Jatropha seeds
comprising:
removing pulp from the seeds,
extracting oil from said seeds using an expeller,
separating oil containing 35% carbon by filter press to remove
sludge,
decreasing carbon percentage from 35% to 10-20% by refining said
filtered oil by a micro-filter of 250-500 mesh, and
further filtering the above oil through a 50-70 mesh micro-filter to
remove sludge and to get better combustion value of the oil.
2. A process as claimed in claim 1 wherein the micro-filters used is 400-450
mesh and 60 mesh respectively.
3. A process for extracting Jatropha Curcas oil from Jatropha seeds
substantially as herein described with reference to the foregoing example.
