Definitions

  • the present invention relates to a biological fuel and method for its production.
  • Vegetable oils have found increased use in recent years as fuels and heating fuels, for example for the operation of combined heat and power plants.
  • the most common oils for this purpose are palm oil, rapeseed oil and soybean oil.
  • soybean oil and palm oil are at the top.
  • Palm oil is the oil that is extracted from the pulp of the oil palm. Palm kernel oil is extracted separately from the palm kernel. Main production sites for palm oil are Malaysia and Indonesia.
  • Vegetable oils require refining before use.
  • the vegetable oil is divided into different fractions, which are suitable for different purposes.
  • Refining palm oil produces an inferior fraction known as "palm fatty acid distillate” (PFAD), which consists largely of free fatty acids.
  • PFAD palm fatty acid distillate
  • free fatty acids have a corrosive effect on machine parts.
  • Corresponding materials can therefore practically not be sensibly used as fuel.
  • DE 10 2006 019 763 A1 describes, for example, a method for reacting acid fats and oils with polyhydric alcohols.
  • the aim of this document is a substantially complete implementation, for example with the polyhydric alcohol glycerol, as this high calorific values are achieved.
  • the object of the present invention was therefore to provide a fuel which avoids the disadvantages of the prior art.
  • a palm oil fatty acid-containing educt in particular PATH
  • glycerol is reacted with glycerol, whereby not a complete conversion to triglycerides is desired, but the aim is to obtain a mixture of mono-, di- and triglycerides.
  • the palm oil-containing product comes from the refining of palm oil.
  • the interfering ingredients are especially in the reaction product solids, therefore, it is preferred that the fuel of the invention contains less than 5 mg residue / kg fuel on a 0.8 micron filter.
  • Suitable starting materials are in particular fatty acid-containing products with a content of free fatty acids (FFA)> 85 wt .-%. FFA is determined according to DIN EN 14104 (2003).
  • the fuel according to the invention has a calorific value of at least 35,000 joules / g, preferably the calorific value is somewhat higher, preferably at least 36,000 joules / g.
  • the biological fuel according to the invention is prepared by esterifying the palm oil fatty acid-containing starting materials, in particular PATH, with glycerol during the esterification, during which a reaction control takes place and the reaction is stopped if the content of tri-, di- and monoglycerides is in the range claimed according to the invention.
  • the PATH was heated to 87 ° C and the glycerol added. The mixture was then heated to 230 ° C over 285 minutes, thereby forming an intermediate plateau at the temperature of 170-190 ° C.
  • the pressure was 200 mbar.
  • the mixture was pumped to a filtration unit using the heat of the mixture to preheat the next PFAD batch.
  • a filtration was carried out with the addition of different grain sizes of perlites.
  • the product obtained had the following specification: Energy: 35509 y / g FFA: 1.2% monoglycerides: about 10% by weight diglycerides: about 35% by weight triglycerides: about 55% by weight.
  • the FFA content was monitored continuously. At an FFA content of 1.5% after 420 minutes, the reaction was stopped.
  • Example 1 It was cooled and filtered as in Example 1.
  • the product obtained had the following specification: Energy: 25110 yr FFA: 1.5% monoglycerides: about 15% by weight diglycerides: about 35% by weight triglycerides: about 50 wt .-%.
