Ethanol blending: A technological knowhow!

Ethanol blending is a process of adding ethanol to petrol. Because of the growing environmental concerns, the use of ethanol as a motor fuel or as an additive is gaining rapid popularity. Properties of Ethanol closely resembles petrol. Moreover, you can obtain ethanol from various plants making it a renewable fuel.

Properties of ethanol:

Chemically, ethanol i.e. ethyl alcohol (C2H5OH) is a clear, colorless and flammable liquid. It has an octane number of 108 which is higher in comparison to standard gasoline.

Various sources of ethanol:

Ethanol can either be manufactured from petroleum products or from biomass. In the former case, ethylene is the raw material whereas, in latter, various plant-based materials serve the purpose. Ethanol obtained from the material of plant origin is called bio-ethanol. Sugarcane, Maize, Potato, Sweet-potato, agricultural waste are some of the major raw materials for the production of bio-ethanol. Fermentation of plant material of this ilk yields ethanol.

Nomenclature of ethanol fuels:

Worldwide, the automotive industry has adopted a standard nomenclature to denote ethanol fuels which is EX.

Here, E stands for Ethanol. X is a number denoting the percentage of ethanol in fuel by volume.

According to the above nomenclature, E10 means fuel that contains 10% by volume of ethanol.
