- The Production of Ethanol
- CrudeOil
- Cracking of the naptha fraction
- Ethene
- 300 degrees
- 60 atmospheres
- Phosphoric Acid (H3PO4) catalyst
- Water (H2O)
- Advantages
- Relatively fast
- Process is continuous
- Produces pure ethanol
- Disadvantages
- Requires high technology
- Uses a lot of energy
- Crude Oil is a non renewable source of energy
- Ethene
- Cracking of the naptha fraction
- Fermentation
- Glucose
- 35-55 degrees
- Compromised temperature for enzymes to function
- Absence of air (no oxygen)
- This prevents oxidation of ethanol to ethanoic acid
- Anaerobic respiration of yeast
- Advantages
- low technology process - can be used anywhere
- It does not use much energy
- Sugar cane is a raw material - renewable source
- Disadvantages
- Batch Process - once 15% of ethanol is produced, enzymes stop working
- Vessel must be emptied before reaction can start again
- Relatively slow process
- Produces fairly impure ethanol
- Batch Process - once 15% of ethanol is produced, enzymes stop working
- 35-55 degrees
- Glucose
- CrudeOil
