Question

Which is a better crop for biodiesel Jatropha or Pongamia?

Answer 1

Hi

i will help u in this question.....

plzz make sure that ure knowledge is vast....

i will make things clear........

Jatopha...well...we know its a genus...

also called as..............physic-nut tree

Currently the oil from Jatropha curcas seeds can be used for making biodiesel fuel in India...................

Jatopha is being promoted as an easily grown biofuel crop in hundreds of projects throughout India and other third world countries

The rail line between Mumbai and Delhi is planted with Jatropha and the train itself runs on 15-20% biodiesel.

The plant can grow in wastelands, and it yields more than four times as much fuel per hectare as soybean, and about half as much as corn. A hectare of jatropha produces 1,892 liters of fuel (about 6.5 barrels per acre). ................

MY KNOWLEDGE ON  THIS

Bushy jatropha plant and developing a converter to allow the oil to withstand extremes of temperature, has high hopes for the innovative car.

this is the world's first pure biodiesel to run a car.............

It is especially attractive because it grows naturally through much of arid India, having very deep roots to reach water, and is one of the few crops well-suited to commercialization by India's large population of rural poor

WELL,now we come to......Pongamia pinnata

(Indian Beech Tree or Pongam Tree, Panigrahi)

The seed oil is an important asset of this tree having been used as lamp oil, in soap making, and as a lubricant for thousands of years. This oil is rapidly gaining popularity as an important source of fuel for diesel engines.

i used it to run a 5 HP engine...there are better and cheaper fuels than this Pongamia oil....k

Pressing the seed produces 25 per cent oil and 70 per cent residue (known as cake), assuming 5 per cent losses. This is a high oil yield compared with some other seeds. The main drawback is that the cake is non-edible and so is unsuitable for animal feed. Nevertheless it can be used for composting or producing biogas.

another fact is that....

Already one large-scale industrial producer - Dandeli Ferroalloys - has converted all five of its 1-megawatt diesel generators to run on the Pongamia..oil. The company claims that using the oil instead of diesel has saved them money.

Most tree-based oil seeds yield about 25 per cent oil and 70 per cent cake after taking into account losses of around 5 percent in the process of oil extraction using rudimentarty expellers – implying that a hectare of land under Pongamia could potentially yield 2.5 tonnes of oil that has comparable value to diesel as fuel  

A litre of Pongamia  is equivalent in performance to a litre of diesel

ADVANTAGES.....

Pongamia oil is available in expelled form at around Rs.20 per litre, ie, at a 10-15% discount to the price of diesel.

   If a farmer buys the seeds at Rs.3.50 per kilo, has it milled and sells the oil cake at Rs.3 per kg, the cost of the bio-fuel (equal to a litre of diesel) is Rs.9 per litre, ie, a 60% discount to the price of diesel.

  If the farmer collected the seeds free from his land, had it milled and sold the oil cake at Rs.3 per kG, the cost of oil to him was Rs.4 per litre, which is an incredible 80% discount to the price of diesel.

above all...

finally i say that its much better to use Pongamia oil...............for bio diesel..........

HOPE THIS IS THE BEST ANSWER UVE GOT..........

ALL THE BEST................USE PONGAMIA..K..

Answer 2

It would depend on where you are. If you are currently in India, the government is offering incentives to start with Pongamia farming. I am not sure about Jatropha, but if the government offers help with one and not the other, my guess is it is a better, earlier, and less problematic crop. The trick to either is to find a product like corn or rapeseed to inter-plant or double crop. You would then have an oil product immediately while waiting for the main crop to mature and produce. Picking a crop not only for cover and protection around your main crop is a good sense practice and you should explore that. As far as maturity production rates and turnover, I have no information but some on line research will provide that for you.

What is even better than biodiesel?    Using water for fuel...

Nasa is researching using water for rocket fuel.   Why not use it in cars?
