Biodiesel Production

  
   


Because the cost of diesohol production, in particular the emulsifier added, was high, so the experiment changed to focus on biodiesel production.

  
     
  To produce biodiesel, the used cooking oil will be warmed at about 60
degrees Celcius while Sodium Hydroxide is diluted in 99.5% ethyl-alcohol.
Mix the two solutions together in the reaction tank and leave for about 90
minutes. In the esterification process, glycerol will be separated from
biodiesel. Remove the glycerol on the bottom and clean the biodiesel with
clean water. Glycerol, the byproduct of the esterification process, can be purified and can then be used to produce soap.
