Ethanol may be produced either by the fermentation of aqueous glucose or by the catalytic addition of steam to ethene. What are two advantages of producing ethanol by the catalytic addition of steam to ethene instead of by the fermentation of aqueous glucose?
- Afaster reaction and renewable raw materials
- Bpurer product and faster reaction
- Crenewable raw materials and continuous process
- Duses more energy and forms a purer product
