  1. Grease to Gas: Biodiesel Basics

  2. Today we will…. • Examine why biodiesel is an important alternative fuel to petroleum based diesel • Learn how different percentages of biodiesel can be combined with conventional diesel fuel (B factor) • Make Biodiesel! • Watch a Dirty Jobs Video about biodiesel • Play a Biodiesel game

  3. Made from crude oil at high temperatures Difficult to make on small scale Made from renewable resources Relatively Easy to make on both small and large scale Less Carbon Emissions than petroleum based Diesel Biodegradable Biodiesel v. Diesel

  4. Where Biodiesel is Made: Small Scale Production Large Scale Production

  5. Ethanol and FlexFuel Drawbacks?

  6. How Biodiesel is Made:

  7. The “B” Factor • There are many combinations of conventional diesel and Biodiesel that can be found at many gas stations across the U.S. • B2: A mixture composed of 2% Biodiesel with 98% petrol (conventional) diesel • B5: A mixture composed of 5% Biodiesel with 95% petrol diesel. • B20: A mixture composed of 20% Biodiesel with 80% petrol diesel. • B100 or Neat Biodiesel: Composed of 100% Biodiesel.

  8. Is Making Biodiesel….a Dirty Job??

  9. What does it take to make Biodiesel? • Lye • Vegetable Oil • Methanol • Mixing Device • Measurement Tools • Safety Gear

  10. Caution Lye will burn if you come in contact! If exposure to lye occurs: Flush affected area with water for 30 – 60 minutes with water and contact 911

  11. Please wear your safety equipment • Safety Goggles • Rubber Gloves

  12. Preparation • Make sure all surfaces can be easily cleaned. Put all books away on all tables where the project will take place. • Put safety goggles on along with rubber gloves. Remember the chemicals you are dealing with have the ability to burn and scar. • Due to the caustic nature of the chemicals we do not want to risk a spill or splash so please start with the slowest speed on the mixer and slowly increase.

  13. Procedure • Measure 100 Millilitersof the Methanol into a glass beaker. (Make sure cap is replaced) • Pour Methanol into the Erlenmeyer flask • With the spoon weigh out 1.75 grams of lye on your scale. (Instructor will do this step) • Put the lye into the Erlenmeyer flask and blend softly on the first setting • Blend for 2 minutes • Blend 1/2 Liter of Vegetable Oil. • Blend for 20min on first or second setting. (Ideally creates a small vortex)

  14. Methanol Test • Purpose: To check the purity of the biodiesel to see if it could be an engine without causing problems. • Measure out 225 milliliters of Methanol in a cleaned beaker. • Take 25 milliliters of the biodiesel and add it to the measured methanol. • If there is un-dissolved solution at the bottom of the beaker, this means that the biodiesel is impure. This could be from humidity or water from the air that got into the solution or it could be from impure vegetable oil. • Clean the beaker again: (make sure to keep gloves and goggles on)

  15. Clean Up • Clean up while the biodiesel is blending. • Please keep your gloves and eye goggles on for the cleaning of the materials. • Beakers need to be cleaned in hot soapy water. • Vegetable oil and lye need to be returned to the front of the class.

  16. Biodiesel Game: • Please split into 2 groups • 1 Person from the team comes up and gives hints as to what the word on the flash card is with out saying the word • Each team will have 3 minutes to guess as many words as they can, then the next team will go
