Transcript of Alternative Energy: Ethanol and Methanol

Conclusion Chemical formula: CH3OH

Production
Cheaper
From natural gas, feedstocks

Compared to gasoline:
Less flammable
Reduces emission rate
Higher engine efficiency
Less environmental pollution What about Methanol? Lower energy content than gasoline
Not nationally distributed
Lead to shortage of grain products
Very corrosive Cons of Ethanol Methanol Historical Facts Reduces greenhouse gas emission
Positive Energy Balance
Produced domestically
Jobs in rural areas
In more than 95% of gasoline sold in U.S. Why Ethanol Continued... E10 - Gasohol
10% ethanol and 90% gasoline
"Substantially similar" to gasoline
In most vehicles Ethanol and Gasoline Blends Chemical formula: C2H5OH

Alcohol-based fuel
High quality, high octane
Trillions of miles driven
From cellulosic biomass

Current Usages
Motorboat
Lawnmower
Cars
Snowmobiles What is Ethanol?
Winter Oxyfuel Program
Ethanol
In cities with elevated CO levels

Year-round Reformulated Gasoline Program
MTBE
Less volatile than ethanol
Reformulated gasoline (RFG)
Less-polluting option CAA's Oxygenated Gasoline Programs Oxygenated gasoline
Combat air pollution
Oxygenate additives:
-Methyl tertiary-butyl ether (MTBE)
-Ethanol
Why increase oxygen content? Clean Air Act Amendments of 1990
(CAA) Maureen Bennett, Chao Ji, Jack Kang, & Edward Lee Alternative Fuels:
Ethanol and Methanol
Corrosive
Lower energy content
Severe health effects
Unpleasant odor
Renewable
Produced within U.S.
Compared to gasoline:
Higher octane ring
Lower production cost
Less volatile Methanol Pros and Cons http://www.afdc.energy.gov/fuels/ethanol_fuel_basics.html

http://science.jrank.org/pages/2575/Ethanol-Advantages-ethanol-an-alternative-fuel.html Harmless to the environment
Higher horsepower than gasoline
High energy density Why Ethanol? http://chemed.chem.purdue.edu/demos/main_pages/5.17.html 2 CH3OH(l) + 3 O2(g) -> 2 CO2(g) + 4 H2O(g)

Exothermic reaction
Energy released: 680 kJ/mol methanol Combustion of Methanol http://chemed.chem.purdue.edu/demos/main_pages/5.17.html http://wwwchem.csustan.edu/consumer/fuels/heats%20.htm
C2H5OH (l) + 3O2(g) --> 2CO2 (g) + 3H2O (l)

Exothermic
Energy released: 1276 kJ/mol ethanol Combustion of Ethanol http://www.tumblr.com/tagged/model%20t%20ford

http://www.fuel-testers.com/ethanol_fuel_history.html Samuel Morey
Turpentine/ethanol engine
Michael Faraday
Synthetic ethanol
Henry Ford
Automobile utilizing ethanol Ethanol Historical Facts 1661, discovered by Robert Boyle

1923, synthetic methanol

1970s, oil crisis --> methanol as motor fuel

1900s, over 20,000 vehicles use methanol/gasoline

Modern production with catalysts

Ethanol over methanol
Clean production
Renewable fuel

So, why consider alternative
energy if we already have
gasoline? http://www.afdc.energy.gov/fuels/images/ethanol-chart-economic-impact.png http://www.afdc.energy.gov/fuels/ethanol_fuel_basics.html
