Making Ethanol

Ethanol can be produced via 2 main methods: Fermentation as well as Hydration of ethene. Fermentation produces less pure ethanol and requires anaerobic conditions, glucose with yeast. Hydration of ethene is more expensive and requires excess steam at high temperatures with phosphoric acid.
