Things to remember

• Heat oil to about 130-140 F. You can use a hot
  plate or microwave (about 2 ½ minutes.
• Wear eye protection and gloves.
• Making biodiesel requires patience to let the
  mixtures set and separate out.

4
If a students is too aggressive is shaking the
biodiesel in the washing process, and emulsion
could occur. Notice on top, the biodiesel is
beginning to separate. Reheating the mixture
(after draining water) can break the emulsion.
5
Time Line for Making Biodiesel in a Lab Setting

• Have students collect two 2 liter coke jugs
• Wash out the jugs and allow to dry no water in
  the jugs!
• Day one Heat up a liter of so of the oil and
  have each student titrate the oil. You can also
  do this in pairs, depending on class size.
  Complete the titration worksheet.

6

• Have on had a few mason jars or mayonnaise jars
  (glass jars with sealable lids)
• Have students pour 225 ml of methanol into the
  jar.
• Measure correct amount of NaOH on triple beam
  scales. Add the NaOH and swirl gently (heat is
  generated as this is a exothermic reaction- hey-
  this correlates with chemistry frameworks!!!)
• These activities may take one or two days
  depending on class size.

7
Start a New Day Here

• Have students heat their oil to 130 f.
• Use a funnel and add the methoxide to the jug.
• Shake vigorously for about 30 seconds.
• Shake vigorously again every 10 minutes or so.
• During the last 15 minutes of class, have the
  students add 50 ml of warm water to the mixture.
  Shake with medium force and store the jug in a
  safe place so the it can settle until the next
  day.
• DO NOT FORGET TO USE EYE PROTECTION AND GLOVES

8
Next Day

• Have students drain off glycerin layer.
• Add about 300 ml of hot water to the jug.
• Shake medium for about 30 seconds and let settle
  for about thirty minutes.
• Drain the soapy water.
• Repeat the steps above.
• When the water remains clear after shaking, all
  soap has been removed.

9
Next Day

• Use a fish tank bubbler to bubble dry (remove
  remaining suspended water) the biodiesel.
• The biodiesel can also be placed outside in the
  sunlight or in the greenhouse to dry.
• The hazy appearance of the biodiesel at this
  point is due to tiny droplets of water.

Appleseed Processor Setup
12
This setup is referred to as an Appleseed
Processor. It is simply a water heater with a
circulating exterior pump. The drain at the
bottom feeds the intake of the pump. The liquid
is then pumped back to the top and re-circulated.
13
For educational purposes, you can connect an amp
meter and have the students calculate the time it
takes to heat up the oil. Using W VA, they can
calculate the amount of Kwh needed to heat the
oil, then calculate the cost of electricity. A
good differentiation project for GT kids.

35 Gallon Washing/Drying Tank
15
A water hose can be connected to drain off water
or a short hose can be connected to drain
biodiesel to a 5 gallon bucket. You can also
connect a transfer pump. The clear tubing is
used to determine the end of water or glycerine
and the beginning of biodiesel.

Other Related Information

• A bushel of soybeans produces appr. 1.4 gallons
  of oil
• If a person averaged using 40 gallons of diesel
  fuel per month, it would take 14 acres to grow
  the beans necessary to produce the oil (25 bushel
  yld, 342 bushels)
• My family of 4 uses about 1700 kwh of electricity
  a month. Burning biodiesel in a generator to
  produce that amount would take 1632 gallons/year
  (46 acres of 25 bu. beans, 1165 bu). Data shows
  that a diesel powered generator uses.08 gallons
  per kwh
