  1. Making Bio-fuels TAF Academy Members: Sebastian Sandoval, Lorenzo Scott, Marvin Aguirre, Jeue’l Asherz, Khalil Rahman

  2. Significance For Study -Petroleum will not sustain the United States much longer therefore alternative energy sources must be pursued. -One solution is biofuels which are created from organic compounds. -By analyzing different types of biofuel we can determine what would best su

  3. Research Question and Hypothesis Question: How will corn ethanol preform in a RPM test? Hypothesis: Because corn is a starch which is amore complex sugar than sugarcane (disaccharide) meaning it will yield well in a RPM test.

  4. Design IV: The Bio-fuel corn DV: The amount of RPMs we get for each of the bio-fuels Constants: -Engine -Amount of each bio-fuel put into engine Controls: Regular Gasoline on the engine to see if bio-fuels can compare

  5. Next Steps -We plan on distilling our alcohol to get a higher concentration, then we will test the RPM’s lawnmower

  6. Process to ferment To prepare we had to boil the corn mash with an enzyme that breaks down/ weakens the cell wall. Then we have to let the corn ferment for about 1-2 weeks After it has fermented we would have to distill.

  7. Our Results After fermenting 2000mL of corn ethanol for a week we then tested for the alcohol percentage using a hydrometer. Alcohol Percentage w/out distilling: 2%

  8. Cellulose • Cellulose is a complex linear polysaccharide • Consists of over ten thousand β linked D- glucose units • Formula: CC6H10O5 • Density: 1.50 g/cm(cubed) • A and B structures: two forms of Cellulose. • A form is weakest structure • B form in the strongest structure • Found in plants and organic materials

  9. Current uses of Cellulose

  10. Why Cellulose? • Cellulose can be used as a fuel source • Complex polysaccharides broken down = multiple glucose particles • Glucose converts into ethanol • Ethanol can be used as an alternative less severe fuel source • Cellulose is found everywhere • Easily accessible and renewable resource

  11. Lab Materials Hydrometer 6.5 Gallon Tachometer
