2 Objective Upon the successful completion of this module, participants will be able to describe the process involved in the production of biodiesel.
3 Introduction Biodiesel used to reduce high fuel prices & global warming Plants increasing across country Easy enough to make many people choose to do it at home
Transesterification Plant oils have chemical structure altered through use of alcohol & chemical catalyst: –Thins & clarifies oil enough to be usable in engines Plant oils & animal fats heated & alcohol & catalyst added Mixed & allowed to settle 4
Transesterification Settles in 2 or 3 layers: –Top layer: Biodiesel (ester) –Middle layer: Soap compound –Bottom layer: Glycerin 5 Property of DOE, reprinted with permission
Components Feedstock: –Examples Alcohol: –Reasons why methanol alcohol of choice Catalysts Co-products: –Biodiesel & glycerin 6 Property of DOE, reprinted with permission
Production Facilities Home brewing: –Local codes & ordinances Safety regulations for commercial facilities 7 Property of DOE, reprinted with permission
Hazards of Biodiesel Production Greatest hazard from chemicals needed to produce biodiesel: –Methanol –Sodium hydroxide –Potassium hydroxide 8
Summary Transesterification process Biodiesel safe to use, dangerous to manufacture Chemicals used in transesterification process more hazardous than final product Home breweries 9
