E20 Fuel

About E20 Fuel:

• It is a blend of 20 per cent ethanol and 80 per cent petrol.
• Ethanol is a biofuel derived from crops such as sugarcane, maize, and grains.
• Advantages: It offers a higher octane rating and potentially cleaner combustion, making it a more advanced alternative.
• While regular petrol in India typically has an octane rating of around 91 to 92 RON, E20 fuel comes with a minimum rating of 95 RON.
• This higher octane helps in smoother combustion.

What is Ethanol?

• Ethanol, also known as ethyl alcohol, is a type of alcohol that is commonly used in various applications. 
• Properties: It is a clear, colourless liquid with a characteristic odour and taste. 
• Ethanol has the chemical formula C2H5OH and is composed of carbon, hydrogen, and oxygen atoms. 
• Pure ethanol is nontoxic and biodegradable, and if spilled, they break down into harmless substances. 
• However, fuel ethanol contains denaturants to make fuel ethanol undrinkable.
• How is ethanol sourced?
  • Ethanol can be produced from various sources, but it is often derived from renewable resources such as crops like corn, sugarcane, barley, and wheat.
  • It can also be produced from cellulosic materials like agricultural residues and wood.
