HONGE OIL AS A BIODIESEL
Posted June 23, 2008on:
There are near about 300 varieties of non-edible oil seed bearing trees in India. Many of the foresters were of the view that the Honge Tree is God’s gift to India. It is very versatile tree that grows in land as well as in coastal area and all these without much care. Growing these trees enhances the maintenance of environment of the surrounding and offers employment opportunities. Honge oil is extracted from the seed of Honge tree, whose Latin name is Pongammia Pinnata and whose international name is Pongammia Pinnata Perry. Honge oil can be produced on a commercial scale provided the right strategies are followed.
The performance of the engine with Honge oil is found to be satisfactory. The viscosity of Honge oil has to be corrected by preheating the oil. The output of the engine remains almost the same though the calorific value is slightly lower. Taken into account the sale value of cake which is a good fertilizer, Honge oil works out to be cheaper (i.e. Rs 13 per kg) compared to current price of diesel. The high viscosity of Honge oil interferes with injection process and leads to poor fuel atomization. The high viscosity has to be overcome by using methyl ester honge oil. The transformation of Honge oil to its methyl ester reduces molecular weight to one third, reduces viscosity to one eighth and increases the diesel index.
