  1. From Fryer to Fuel By Troy Criss, USD #259 Wichita School District Northeast Magnet High School, and Jo McCormick, USD #500 Kansas City, Kansas School District Washington High School Funded by the NSF Research Experiences for Teachers: Shaping Inquiry from Feedstock-to-Tailpipe program at the University of Kansas, summer 2010 https://www.cebc.ku.edu/education/RET-2010.shtml For more information, contact: Claudia Bode, bode@ku.edu, 785-864-1647 The Production of Biodiesel

  2. Why are Replacements for Gas and Diesel Needed? I Think, We Think Acitivity Take 3 minutes to write down your ideas for why replacements are needed for gas and diesel In a group of 4 discuss your ideas (5 minutes). Be prepared to share your group’s ideas with the class.

  3. What is Biodiesel? • Renewable resource fuel that can replace petroleum based diesel fuel • Produced from plant oils and maybe from oils from algae

  4. Biodiesel Reaction Triglycerides + methanol  glycerol + biodiesel Biodiesel Fatty Acid Methyl Esters (FAME) Glycerol backbone KOH http://image.absoluteastronomy.com/images/encyclopediaimages/g/ge/generic_biodiesel_reaction1.gif

  5. Source of Triglycerides • Plant oils or animal oils • Soy • Canola • Used fryer oil from restaurants • Algae - promising source but still problems to solve

  6. Biodiesel Production Biodiesel (FAME) Methanol/ KOH Fatty Acid Methyl Esters (FAME) & Glycerin Washing Drying Oil glycerin Biodiesel

  7. Advantages of Biodiesel • Renewable resource • Decreases net CO2 emissions • No changes needed to fueling infrastructure • Biodegradable • Decreases particulate emissions • No changes needed to current diesel engines

  8. Biodiesel Concerns • Cold weather performance • Solvent properties
