    1. Ethanol in our Lives April 4, 2005 The Metabolisms 2 Names of Team Members Ethanol as a fuel additive

    2. Goals & Purposes • General overview Ethanol as a fuel additive • Benefits • Drawbacks • Educating audience • Knowledge is power!

    3. What is Ethanol? • Produced from corn or sugarcane • Known as “grain alcohol” • Clear, colorless liquid • Boiling point = 78.5 C • Water soluble • Density = .79g/cm3 • Least toxic • Generally tasteless

    4. Guess the Ethanol -OR- Food Extracts Canned Meat

    5. Guess the Ethanol -OR- Laundry Detergent Water Softener Salt

    6. Guess the Ethanol -OR- Ant Poison Hairspray

    7. Guess the Ethanol -OR- Ice Packs Vinegar

    8. Pharmaceutical products Cosmetics Alcoholic beverages Perfume Varnish Fuel additive/extender Uses of Ethanol • Paints • Polyester fiber/films • Ink • Anti-freeze

    9. Ethanol as a Fuel • Gasoline Extender • Gasoline Additive • Fuel Cells • Foreseen Uses

    10. History of Ethanol • Henry Ford built first ethanol-fueled automobile • Tax increase • World War II • 1970 Oil Crisis

    11. Chemical Make-up Ethyl Group • H – C – C – O – H H H | | | | H H C2H5OH + 3 O2 2 CO2+ 3 H2O + heat

    12. Dry Milling Breaking down corn Liquefaction How is Ethanol Made? • Preparing the feedstock Wet Milling Presoaked corn 2. Fermenting simple sugars 3. Recovering the alcohol 4. Recovering non-alcohol materials

    13. Pros vs. Cons Advantages: • Could cut U.S. trade deficit • Will create jobs • Environmentally friendly • Reduces U.S. dependences • Safe for all engines Disadvantages: • Amount of energy • Not widely available • Not compatible with all automobiles

    14. In Conclusion … • Advantages outweigh the disadvantages • Cost • Benefits: • Environmentally • Economically
