  2. BioDiesel For Educators

  3. Diesel & Compression Ignition

  4. BioDiesel Vs. “Greasecar” Systems • SVO = Straight Vegetable Oil. • Uses Heaters to reduce SVO’s viscosity. • Requires No Chemistry. • Oil Must be Thoroughly Filtered. • Vehicle Must be Converted for Dual-Fuel Systems. • Converted Vehicle Starts/Shuts down on Diesel or BioDiesel.

  5. 2 Tank “Multi-Fuel” System

  6. What is BioDiesel?

  7. Triglycerides Are Oil

  8. Post Reaction

  9. How do I Make BioDiesel? Here’s what you need… • Lye (NaOH or KOH) • Methyl Alcohol • Oil (New or Used) • Small, Accurate Scale (+/- 1 gram) • Liquid Measurer

  10. BioDiesel & STEM Cirriculum Ways You can use BioDiesel to promote STEM

  11. (Science) Simple Chemistry Easy Projects include; • Titration • Transesterification • Soap Test (Bromophenol Blue & HCL) • Water Washing • Soap Making • Glycerol Byproduct • Oil

  12. (Science) Advanced Chemistry More advanced projects; • Glycerol Purification (can be done for soap) • Acid Esterification • Ion Exchange Resin (Dry Wash) • Testing for Water • Gas Chromatography (with University/Fed help) • Gateway into Organic Chemistry

  13. Technology • Processing • Mixing • Pumping • Plumbing • Working by Gauges • Oil Purification • Filtering • Drying

  14. Technology (2) • Washing • Water Washing • Dry Washing (Ion Exchange Resin) • Methanol Recovery • Steam Distillation • Vacuum Distillation

  15. Engineering Chemical • Industrial Fuel Production • Continuous Processors • Solid Catalysts • Challenges with Algae Mechanical • Diesel Technology • 4 Cycle Principles • High Pressure Injection

  16. Math • Working with Decimals & Fractions • Understanding Formulas • Graphing Emissions Chemistry Related • Molar Weights • Valence Shell
