WARMUPWhat do you think about funding research for alternative sources of diesel?

Where should we start and how much time/ money should we put into it?

REMINDERQuiz next class

◦Study notes, homework, review sheet

What is Diesel?The primary oil used in motor

vehicles

What is biodiesel?Type of diesel developed from

vegetable oil!◦Can also be made from fats and

greases

BenefitsRenewable

Only takes crops a year to grow

Give off less pollution when burned

Reduction in land destruction

Safer to handle

Nontoxic

NegativesLower fuel efficiency

Does not do well in cold weather

Takes a lot of oil to produce necessary amount

Take more time to process and transport

CurrentlyBiodiesel is the fastest growing

alternative fuel source!!

What You Will Be Doing TodayMaking your own biodiesel!!!

LAB REPORTFollow rubric on my wiki!!!!!

Pick reliable individuals to work with.◦If you choose to do an entire lab

report on your own you need to let me know.

◦The lab report can also be turned in before the due date for me to edit

◦LAB REPORT DUE-> 04/26/2013

Lab QuestionsQuestions: 1. What changes did you see between the characteristics

of the starting materials (cooking oil, methanol, and potassium hydroxide solution) and the final products (biodiesel and glycerol)? What evidence is there that a chemical reaction has occurred?

3. What is the purpose of ‘washing’ the biodiesel mixture with salt water?

 

7. Is biodiesel really green? Explain at least two arguments in support of the idea that biodiesel is a “greener” fuel. Also present one argument that biodiesel is not a “greener” fuel. Reference your lab data when appropriate.
