Experiment: Production of Bioethanol from Sugarcane Molasses

Bioethanol production is a significant part of Industrial Chemistry and Chemical Process Engineering. Bioethanol, a renewable energy source, is produced from biomass like sugarcane molasses. This experiment aims to convert sugarcane molasses into bioethanol using yeast fermentation.

Materials Needed:
  • Sugarcane Molasses
  • Distilled Water
  • Saccharomyces cerevisiae (Yeast)
  • Fermenter (e.g., Erlenmeyer Flask)
  • Thermometer
  • Heating plate
  • Distillation Equipment
  • Hydrometer
Procedure:
  1. Prepare a solution of sugarcane molasses and distilled water in an Erlenmeyer flask. The molasses to water ratio should be around 1:4.
  2. Heat the solution on a heating plate until it reaches a temperature of approximately 80°C. This process helps sterilize the solution and dissolve the molasses completely.
  3. Allow the solution to cool to room temperature.
  4. Once cooled, inoculate the solution with Saccharomyces cerevisiae.
  5. Seal the Erlenmeyer flask and allow the yeast to ferment the solution. This should be done at a temperature of around 27-32°C. This process may take several days to a week.
  6. Monitor the fermentation process regularly using a hydrometer. The fermentation is complete when the specific gravity stabilizes for a couple of days.
  7. Once fermentation is complete, distill the fermented solution using distillation equipment. This will separate the ethanol from the rest of the solution.
  8. Measure the ethanol concentration of the distilled solution using a hydrometer. The solution should have an ethanol concentration of around 15-20%.
Safety Precautions:
  • Wear appropriate safety goggles and gloves throughout the experiment.
  • Handle the heating plate and distillation equipment with care to avoid burns.
  • Work in a well-ventilated area to avoid inhaling ethanol vapors.
  • Dispose of waste materials responsibly according to local regulations.
Significance:

The production of bioethanol from sugarcane molasses represents an important aspect of Industrial Chemistry and Chemical Process Engineering, highlighting the conversion of biomass into a valuable fuel source. This experiment demonstrates that common agricultural waste products, such as molasses, can be used to create a renewable, environmentally friendly fuel source. Such processes reduce dependence on fossil fuels, increase energy security, and can stimulate rural development and jobs while reducing carbon emissions.

Further Considerations: This experiment provides a basic overview. Optimizing factors such as yeast strain, fermentation time, and temperature can significantly impact ethanol yield. More advanced techniques, such as using immobilized enzymes or membrane separation, can improve efficiency and purity.
