Biodiesel Consumption

Fuel Consumption (million tons per year)

• 2005 50

• 2020 (exp) 44

2005 Biodiesel (est.) 1.4

2020 Biodiesel (exp.) 11.1

Applied Catalysts

• NaOH in solution of methanol

• NaOCH3 mixed with methanol – ready for the transesterification process

• Acidic systems as sulfuric acid

• Under research: solid systems to improve phase separation and product purification

Biodiesel in Laboratory

Biofuels, Synthetic Fuelsin the German Market

Example: Protein production from oil seeds residues

Process Explanation(acc. Burcon)

• Input from truck: filter cake

• Mixing and extraction with a specific solution and filtering

• Concentratioon and purification

• Diluting before spray drying

• Product: high value protein for human nutrition

Trends

• Broadening of substrate basis: e.g used kitchen oil, fats from waste water treatment (skimmer)

• Improve purity and stability against decomposition• Standardization and quality control of biofuels• Car manufacturers optimize the engine performance for operation

with biodiesel (stability of materials, lubrication proprties)• Biodiesel production: improvements of phase separation, solid

catalysts (e.g. acidic modified cabohydrates)• Besides biodiesel so called BTL-fuel („Choren-Process“, „SunFuel“)

will be available with higher contributions from solid biomass• Today: cars operated with compressed natural gas can compete

with biodiesel vehicles, they serve a growing market• Utilization of byproducts: glycerol, proteins
