Essay On Fossil Fuel

ABSTRACT
Fossil fuels are mostly used in the world, but there are number of serious problems with burning these fuels to provide energy. They cause significant damage to the environment, which effect the health of people. Due to these problems that have made alternative source, renewable source of energy a more attractive option since they do not produced the same kind of pollution and problems. Most important problem is that fossil fuels are non-renewable and limited stock in the world and once they are gone they will be gone forever. The increasing awareness of depletion of fossil fuels resources and the environmental benefit of biodiesel fuel has made it more attractive in present scenario. Biodiesel is alternative to petroleum based fuels

The properties of linseed oil is similar or nearest the diesel so it can be easily used in place of diesel fuel without or minor changes in diesel engine , for avoid the NOx formation or avoid any minor engine damage due to its low cloud point it can be easily blend in diesel in different ratio and it is the best way for reduced the fuel scarcity problem.

Conclusions
Linseed oil is an important oilseed crop and it has a rich source of fatty acid that is 45 to 49 %. It can be easily grow in any soil condition. [29] And it is most important crop for reducing the fuel scarcity problem and reduces the emission from diesel engine. The conclusions of whole thesis are:
 The maximum amount of biodiesel is produced in 6:1 molar ratio and in 1% catalyst.
 When the stirrer time is increases the %value of yield is increase, max time is 30min.
 The properties of biodiesel are nearest to the diesel fuel so it can be easily used.
 For reducing the NOx formation it can be blend in diesel in different
