1. From Fryer to Fuel The Production of Biodiesel 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, 785-864-1647bode@ku.edu

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 Glycerol backbone http://image.absoluteastronomy.com/images/encyclopediaimages/g/ge/generic_biodiesel_reaction1.gif KOH Biodiesel Fatty Acid Methyl Esters (FAME)

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 Methanol/ KOH Oil Fatty Acid Methyl Esters (FAME) & Glycerin Washing Dryin g Biodiesel (FAME) Biodiesel glycerin

7. Advantages of Biodiesel Renewable resource Decreases net CO 2 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
