Ethanol can be produced either by the fermentation of sugars or by the catalytic hydration of ethene. Which row gives an advantage of each method?
- Afermentation produces purer ethanol; hydration is a batch process
- Bfermentation produces purer ethanol; hydration is a continuous process
- Cfermentation uses a renewable resource; hydration is a batch process
- Dfermentation uses a renewable resource; hydration is a continuous process
