MANUFACTURING PROCESSES
Ethanol is produced both as a petrochemical, through the hydration of ethylene, as well as via biological processes, by fermenting sugars with yeast.
(I). Ethylene hydration (Production of Synthetic Ethanol)
Ethanol for use as an industrial feedstock or solvent is made from petrochemical feed stocks, primarily by the acid-catalyzed hydration of ethylene.
Chemical reaction:
C2H4 + H2O  CH3CH2OH
(II). Fermentation (Production of Bio-ethanol)
Ethanol in alcoholic beverages and fuel is produced by fermentation. Certain species of yeast (e.g., Saccharomyces cerevisiae) metabolize sugar,
producing ethanol and carbon dioxide.
Chemical reactions:
C6H12O6  2CH3CH2OH + 2CO2
C12H22O11 + H2O  4CH3CH2OH + 4CO2

The ethanol market is expected to register a CAGR of around
6%, during the forecast period.
The major factors driving the growth of the market studied are
the rising demand for ethanol as biofuel, growing to use in
beer production and food processing, and stringent
government policies to restrict the usage of fossil fuels.
On the flip side, an increase in awareness about the ill effects
of alcohol consumption, and the advent of hybrid electric
vehicles are likely to hamper the growth of the market
studied.
