E20 Fuel:

The Central government has implemented a new fuel mandate for petrol pumps to supply E20 fuel with a minimum octane rating of 95 RON.
- E20 Fuel 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.
- 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.
- Ethanol, also known as ethyl alcohol, is a type of alcohol that is commonly used in various applications.
- 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.
- 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.
