Indian Railways' technical advisor Research Design and Standards Organisation (RDSO), with the Indian Oil Corporation Ltd (IOCL) has developed a special fuel Methanol Diesel-15.

About Methanol Diesel-15 fuel

  • It is a special fuel developed by the Indian Railways’ Research Design and Standards Organisation (RDSO) in collaboration with the Indian Oil Corporation Ltd (IOCL).
  • It is a cost-effective blended fuel containing 15% methanol, 71% mineral diesel, and 14% indigenously developed additives by IOCL.

What are the benefits of MD-15?

  • It offers superior performance, combustion, and emission characteristics compared to regular mineral diesel fuel.
  • It has the potential to reduce diesel consumption by 15% and result in substantial annual savings.
  • It significantly decreases harmful pollutant emissions, contributing to a cleaner and greener environment.
  • The NOx emissions were significantly lower thus reducing the harmful pollutants, which causes smog and pollution,

Key facts about Methanol

  • It is also called methyl alcohol, wood alcohol, or wood spirit.
  • It is the simplest of a long series of organic compounds called alcohols, consisting of a methyl group (CH3) linked with a hydroxy group (OH). 
  • It completely mixes with water.
  • Production
    • This fuel is generally produced by steam-reforming natural gas to create a synthesis gas.
    • Feeding this synthesis gas into a reactor with a catalyst produces methanol and water vapor.
  • Application: Used to make chemicals, to remove water from automotive and aviation fuels, as a solvent for paints and plastics and as an ingredient in a wide variety of products.

Q1) What is Nitrogen dioxide?

It is a reddish-brown gas with the chemical formula NO2. It is one of the most significant and harmful nitrogen oxides. NO2 is a major component of smog and is a potent respiratory irritant. It is a byproduct of the reaction of nitric oxide (NO) with oxygen in the atmosphere.
