World energy crisis and its reasons Reasons of Increased consumption rate of Energy Impact of increased connsumption of fossil

fuels Biofuels are the ideal substitute of fossil fuels Feedstock for production of biofuel Palm oil as one of the feedstocks for biofuel

production Worldwide palm oil production Results of a research work done in the fats and

oils department on palm oil as biodiesel.

Increase of Consmption

Rate of Energy

Decrease in Natural

Fuel Resources

Rate of energy consumption= world populationx consumption rate per

capita

& Increase of

world population

Increase of average

consumption rate per capita

Disappearance of large areas of land on the earth in

the expected future

Partial melting of the ice mountains at the north pole of the earth

Increase of the earth temperature

Increased emission of carbon dioxide

Forest fires Storms

Soil dryness

Other environmental changes due to increase in global temperature

Renewable and sustainable

Environmentally friendly

Decrease carbon dioxide

emissions

Main source is plants

Cellulosic substance for bioethanol

production

Oils for biodiesel and biojet production

Feedstock for Biodiesel Production

Jatropha

Castor beans

Palm oil biodiesel is advantageous over regular diesel in six points being:

1-Free of sulfur(less environmental pollution) 2-Has lower pour point(ease of handling in cold

weather) 3-Has higher flash point(safer) 4-No ashes are left after combustion(less wear of

engine parts) 5- No residual carbon(less coking deposits in

valves and piston) 6-The brake thermal efficiency of the engine

improves by blending biodiesel with regular diesel fuel(better engine performance)
