What is Ethanol?
Ethanol is a colorless, flammable liquid. Its chemical formula is C₂H₅OH. It is a primary alcohol, and its typical alcoholic smell is so well known, it is prototypical. It is obtained naturally during fermentation of sugars by yeasts, while it is also synthesized industrially. This versatile compound has highly extensive uses in beverages, as a solvent, and as an additive in fuels.
Production of Ethanol
- Fermentation: This is the initial stage where yeast converts sugars from grains or fruits into ethanol and carbon dioxide. The process is simple yet effective, making it a primary method of production.
- Distillation: After fermentation, the mixture is heated to separate and concentrate the ethanol vapor, which is then condensed to achieve higher ethanol content.
- Dehydration: To obtain anhydrous ethanol, a dehydration process is employed, reducing the water content to less than 1%.
Major Ethanol Blends
- E10: This blend contains 10% ethanol and 90% gasoline, commonly used to reduce emissions and improve engine performance.
- E20: Featuring 20% ethanol and 80% gasoline, this blend offers greater environmental benefits while maintaining compatibility with most engines.
- Flex Fuel Vehicles: These vehicles are engineered to run on various ethanol-gasoline blends, including E85, providing flexibility and promoting ethanol use.
