E20 Fuel Latest News

The Central government has implemented a new fuel mandate for petrol pumps to supply E20 fuel with a minimum octane rating of 95 RON.

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.

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.
