3. Ethanol can be produced by two different processes:
Hydration and fermentation.
Ethanol can be produced by hydration of ethene with
steam in the presence of a catalyst.
ethene + steam ethanol
C2H4 + H2O C2H5OH
4. Ethanol can also be produced by fermentation with
yeast, using renewable resources.
This can be represented by:
sugar carbon dioxide + ethanol
C6H12O6 2CO2 + 2C2H5OH
Using ethane to make ethanol needs non-
renewable crude oil as its raw material, whereas
fermentation uses renewable plant material.
