INTRODUCTION
=Need for clean and pollution free environment.
=World present oil resources may be wiped out in 42 years
=Diesel engine operated on DME fuel has low combustion noise and low emission.
=Fuel is economical and has many utilities.
MANUFACTURING PROCESS OF DME
1.Catalytic dehydration of methanol to DME
2CH3OH CH3OCH3+H2O
2.Direct synthesis of DME
3CO +3H2 CH3OCH3+CO2
CHARACTERISTICS OF DME AS A FUEL
=Gas at ambient temperature and atmospheric pressure.
=Colourless clear liquid under six atmospheres.
=Can be transported and stored as a liquid at low temperatures.
=No sulphur or nitrogen compounds and low toxicity.
=No corrosive effect on metals.
=Oxygenated fuel.
=Combustion is not accompanied by black smoke or soot.
