  1. Bio-diesel Present Situation and Development Prospect Tao Ding

  2. What is biodiesel • Alternative Fuel derived from plant oil • Contains no petroleum but be blended with petroleum diesel • Produced domestically from renewable resources • No engine modification are necessary • Biodegradable, Nontoxic Fuel

  3. Biodeisel Emissions • Compared to petroleum diesel, reduced emission of: --Unburned hydrocarbons --Carbon monoxide --Particulate matter --Sulfur oxides • Overall ~50% less than that for diesel fuel

  4. Biodiesel Production • Transesterification --Chemical process which converts vegetable oil into biodiesel and glycerol

  5. Process Step • Clean and heat biolipid (WVO ) • Titration the WVO sample. (Optimal PH7) • Mix the bioalcohol and catalyst in exact amount • Combine methanol/caustic with biolipid at 50 C, mix and heat for several hours • Separate biodiesel and glycerol and remove alcohol • Purification

  6. 100 lbs. of Soybean oil +10 lbs Methanol=100 lbs. Soy biodiesel+10 lbs of Glycerol

  7. Efficiency and Economic Arguments • According study of U.S Department of Energy, the biodiesel yields 3.2 units of fuel product energy for every unit fossil fuel energy consumed. --Petroleum Diesel 0.843 --Petroleum Gasoline 0.805

  8. Some Research for Biodiesel Source • Traditional plants can not satisfy the energy requirement of the world • A species of algae with oil content of 50% Utilize 0.3% land = All transportation Energy • Desert is the best place because the high solar radiation
