What is Biodiesel? • Processed engine fuel made from vegetable oils and animal fats • B100 – Pure Biodiesel • ASTM D6751 Standard
Seed Preparation • Remove Extraneous Material • Screening • Pass Over Magnet
Oil Extraction • Expeller Pressing or Solvent Extraction • Heat Seeds • Crush Seeds • Oil Extraction – Expeller Press • Crude Oil • Cake
Oil Preparation • Degumming • Remove Phospholipids (gums) • Water Wash • Remove all Water • Water - fatty acids form salts • Heat to 120°C
Processing • Chemical Reaction • Oil plus Alcohol • Yields Fatty Acid Alkyl Esters + Glycerin • Catalyst - Potassium Hydroxide • Proportions: • 10 parts oil - 1 part alcohol • 10 parts biodiesel - 1 part glycerin • Catalyst based on fatty acid content • Requires Excess Alcohol
Quality Factors • ASTM standard D6751 • 18 factors • Purity • Storage • Cold Weather Properties • Engines Operation • Complete Conversion • Catalyst and Glycerin Removed
Biodiesel Quality Factors American Society of Testing and Materials (ASTM) specifications. Biodiesel Standard: ASTM D 6751
Quality Factors • Total Glycerin - Incomplete Reaction • Free Glycerin - Incomplete Washing • May Separate in Storage • Clogs Filters • Total Acid number • Methanol Carryover • Effects on Seals and Hoses
