  1. What is rape diesel fuel? Rape diesel fuel is a fuel which is produced by using rape or soy plants.

  2. How to get rape-oil? You get rape-oil out off rape seeds via extraction with the help of heptane.

  3. How to produce rape diesel fuel? Rape diesel fuel is produced by interesterification of rape-oil and methanol.

  4. Production of rape oil methyl ester (rape diesel fuel/biodiesel)

  5. Fats and oils have quite big molecules with a spinal of glycerol on which are bond three fatty acid rests. By the interesterification, the fatty acid rests are solved from the glycerol and each is bond with methanol. The products are glycerol and three molecules of fatty acid methyl ester.

  6. How stands the viscosity of rape diesel fuel to the viscosity of rape-oil? Rape diesel fuel has a lower one.

  7. Which flash point do rape diesel fuel and normal diesel fuel have? Mineral diesel fuel: 80-100°C Rape diesel fuel: 175-180°C Rape or normal diesel fuel Temperature sensor gas burner

  8. Which fuel value do rape and non-rape diesel fuel have? Rape diesel fuel has a c. 20% lower fuel value than diesel fuel. Consequently, e.g., you need 20% more rape diesel fuel to travel a certain distance by car.

  9. Is rape diesel fuel better for the environment? The biologic products rape-oil and rape diesel fuel are not harmful to the environment. Whereas mineral diesel fuel is very harmful.

  10. Disadvantages of rape diesel fuel • profitability doubtful • production difficult • ignites at higher temperature • only a few petrol stations offering rape diesel fuel (c. 800 in Germany) • use only possible with certain diesel engines • perhaps convertisment necessary • much expenses needed •  much subsity needed

  11. Advantages of Rape diesel fuel • made of growing plants • free of sulphur (< 0.001 %) • lows clearly the emission of soot (up to c. 50 %) • closed CO2 circulation • benzole and other aromatics are not contained • lows the emission of hydrocarbon • easily biodegradable and in case of accident it does not endanger the ground and its water • not a dangerous good • high greasiness and considerates the engine • Environmentally good alternative to mineral diesel fuel

  12. Our comment to : Generally, we think rape diesel fuel is a good alternative to mineral diesel fuel, especially if you have a look on the global situation of our environment. But until it can be used more extensively, intensive research should continue to finally optimise its use. Zurück zur Übersicht Special Thanks to: Wilhelm Wilhelmi
