Going Green, Fuel Style!!The Test of Alcohol
Lamp Oil

Introduction

• Gas prices on rise
• Average 4.10
• Gasoline is infecting the environment

3
Purpose

• By testing the energy output of denatured alcohol
  and lamp oil, we are able to tell which form of
  fuel is the better buy. However, we need to find
  a fuel that will not hinder the environment. In
  this test we were also able to watch the fuels
  burn and see which fuel burned cleaner. Both
  fuels that are being tested are lower safer
  forms of the ethanol and petroleum gas.

4
Hypothesis

• If we burn each fuel for 7 minutes then, the
  alcohol will burn cleaner, but produce less
  thermal output and lamp oil will burn dirtier,
  but produce more thermal output.

Denatured Alcohol

• Advantages
• Low cost, its ability to be extinguished by
  water, and its easier to transport

• Uses
• To kill insects
• In mouthwash
• For camp stoves
• To remove excess dust from sanding wood

• Disadvantages
• Hazardous because the flames are invisible.

6
Lamp Oil

• Uses
• Emergency indoor lighting
• Mood Lighting
• Alternative to candles

• Advantages
• None

• Disadvantages
• More expensive than denatured alcohol

7

Procedure

• Cool 125mL water to 17C.
• Set up stand and clamp on flat surface.
• Put 200mL degenerated alcohol into alcohol burner
  and place under stand.
• Put chilled water and calorimeter can on stand
  above alcohol burner.
• Take initial temperature of water and weight of
  burner.
• Light burner and begin stopwatch.

10
Procedure Contd

• 7. Heat water for 7 minutes.
• 8. Take temperature of water immediately after 7
  minutes.
• 9. Take weight of alcohol burner recording all
  data and observations.
• 10. Repeat steps 4 through 9 for At least 2 more
  trials.
• 11. Repeat steps 3 through 9, replacing alcohol
  with hydrocarbon in step 3, and its trials.
• 12. Calculate the thermal output in calories per
  grams used

Results Contd
Average Alcohol 1243.158 cal/g HC Fuel
1631.054cal/g
15
Conclusion

• Our hypothesis was proven correct.
• Things that could have been done if we had more
  time and resources
• Use ethanol and petroleum gas
• Mix two fuels to see if thermal output is higher
  or lower than the other two.
