Fermentation Process
During fermentation, sugar (glucose) from plant material is converted into ethanol and carbon dioxide. This typically takes place at temperatures of around 30°C. The enzymes found in single-celled fungi (yeast) are the natural catalysts.
Pros & Cons against Hydrogenation
These are some of the advantages and disadvantages of making ethanol by hydration of ethene and by fermentation.
