Title: Catalytic Production of Synthetic Diesel Fuel
After 30 years of research in the area of converting organic materials into diesel, German chemist Dr. Christian Koch succeeded in turning hydrocarbon-based waste into top-grade synthetic diesel fuel.
In a closed circuit, at 220 degrees Celsius and at slightly subnormal pressure, carrier oil and organic material are mixed in a catalytic converter. This process already results in a certain amount of diesel being created, which now serves as an energy carrier for raising the temperature to 280 degrees. It also means that no additional energy is required. Since the entire reaction takes place at below 350 degrees, no toxic gases such as dioxins or furans are formed. Approximately 3 to 8% of the source material remains as a residue in crystalline form and the rest turns into high-grade diesel.
Input materials are hydrocarbons such as paper, carton, wood, biomass, waste oil, any kind of plastic, rubber, tires or even just regular waste. The efficiency of the process depends on the grade of the input material. It begins at 30% with pure biomass materials and ends at 90% with pure plastic. The final product is synthetic diesel at a cetane number of approximately 60; conventional commercial diesel has a cetane number of approximately 50. So synthetic diesel meets the EN 590 standard and can be used with any diesel engine. In addition, as per European Directive EEG 2003/30, this type of diesel fuel is exempt from any taxes as long as the input material comes from second-generation biomass.
