Background Information

What Is Gasoline?

  • Gasoline is a chemical substance made up of carbon and hydrogen
  • Gasoline is used in our everyday lives. Its main purpose is to power motorized vehicles and machines, such as cars and trucks.
  • Gasoline’s chemical formula is C8H18


How Is Gasoline Extracted From Crude Oil/Fossil Fuels?

  • Gasoline is made from crude oil, a fossil fuel
  • Distillation is a procedure that converts crude oil into gasoline
  • During distillation, crude oil is heated and then separated into several components based on their boiling points. One of those components is gasoline.

 

Where Do We Use Fossil Fuels? 

  • Fossil fuels are used to produce energy
  • We see fossil fuels used a lot for transportation such as in cars, trucks, boats, airplanes, etc.
  • Fossil fuels are also used for producing huge amounts of electricity and heating our homes
  • In Alberta, fossil fuels run a big part of the economy and is Canada’s largest producer

 

What Are The Effects of Burning Fossil Fuels On The Environment?

  • One of the biggest effects of burning fossil fuels is the release of harmful gases, known as greenhouse gases, into the atmosphere
  • Greenhouse gases, such as carbon dioxide and other oxides, get trapped in the Earth’s atmosphere
  • This increases Earth’s temperature affecting climate change
  • These pollutants can also affect human health and wildlife

 

What Is Ethanol?

  • The chemical formula for ethanol is CH3CH2OH
  • Ethanol fuel is a mixture of ethanol with gasoline
  • It contains 10% ethanol and 90% gasoline. This is the most common amount (called E10). E100 is also available but is commonly used in labs.

 

How Is Ethanol Made From Plants? 

  • Ethanol is made from plants in a process called fermentation
  • The sugars from starch-based plants such as corn are then converted by yeast into ethanol
  • The US is the largest producer of ethanol  

 

Where Do We Use Ethanol?

  • Ethanol is used in cosmetics, solvents, and in foods/beverages
  • Ethanol fuel can be an alternative solution to pure gasoline such as for vehicles 
  • 100% ethanol is typically not used as car fuel because it does not burn as quickly as gasoline (higher octane) and is very expensive

 

How Are Ethanol And Gasoline Used To Run Cars? 

  • Fuel burns in a car engine through a process called combustion
  • Combustion is a process of controlled explosions
  • A combustion reaction typically involves a hydrocarbon (like gasoline) and oxygen to produce carbon dioxide, water and heat

Data

Which Is A Better Fuel Source? 

Ethanol produces 48%-52% less greenhouse gasses than gasoline. This means that all the greenhouse gasses that gasoline produces is 48%-52% more than that from ethanol fuel.

 

Conclusion

Conclusions

 Ethanol:

  • Ethanol is renewable - made from corn or sugar cane
  • Lower availability compared to gasoline
  • Higher octane rating (the number you find on gas pumps). The higher the number, the better it is at withstanding engine issues.
  • Produces less greenhouse gasses
  • Expensive

 

Gasoline:

  • Gasoline is non-renewable - obtained from crude oil
  • Longer lasting fuel per gallon compared to ethanol
  • Easier to get your hands on at gas stations 
  • Lower octane rating than ethanol
  • Produces more greenhouse gases

 

Therefore, based on my findings, ethanol may be a better fuel source than gasoline for the environment. However, if we look at efficiency, gasoline takes the win!
