Biodiesel

Requirements: -
  • Vegetable Oil
  • Antifreeze (Methanol)
  • Lye (Sodium Hydroxide)
  • Blender
  • Scales
  • Plastic Containers
  • Thermometer
  • Duct Tape
  • Funnels
  • Plastic Bottle with lid

Steps Involved : -

·         Step 1: -
Measure out 200mL of antifreeze and put it in a plastic container.
·         Step 2: -
Add in Lye so that antifreeze is absorbed.
·         Step 3: -
Cover container and mix well by shaking it. It is mixed when it starts to feel warm and is foamy. The mixture now has become Sodium methoxide. 
·         Step 4: -
Blend one litre of vegetable oil with the sodium methoxide in a blender for 20 minutes
·         Step 5: -
Pour the mixture into a bottle and wait 8 hours until the byproduct, glycerin, separates from the biodiesel. The glycerin will be the solid on the bottom.
·         Step 6: -
Separate out the biodiesel by pouring into a glass bottle.
·         Step 7: -
Prepare a wash bottle by poking a small hole in the corner of the bottle and covering it with duct tape.
·         Step 8: -
Wash the biodiesel by pouring it into the wash bottle and adding in a half litre of water. Roll the bottle around to mix it and then remove the duct tape and drain the water.
·         Step 9: -
Repeat the washing process until the biodiesel is clear. This may need to be done numerous times over the course of a week to complete the process. Store the Biodiesel in a glass container until ready to use.
