Definitions

  • the present invention relates to a fuel preparation consisting of at least one vegetable oil monoalcohol ester and an admixture of up to 20
  • a significant improvement is achieved if the readily available rapeseed, soybean and palm oil is completely converted into the corresponding alkyl fatty acid ester by transesterification with short-chain monoalcohols such as methanol, ethanol or propanol.
  • This fuel commonly known as biodiesel, which is widespread on the market today, can be used in most diesel engines without major technical changes. In addition to excellent lubricity, this fuel has a very low sulfur content (EN ISO 20846) and thus achieves a significantly reduced particle emission.
  • biodiesel is also subject to qualitative restrictions compared to the values required for Category IV diesel in the World Fuel Charter 2002.
  • the restrictions include, for example, the low cetane number, the high viscosity and the poor cold properties, which leads to reduced suitability for winter.
  • WO 03/004588 describes that biodiesel is blended with a hydrocarbon mixture obtained from the Fischer-Tropsch synthesis. How
  • WO 03/004588 describes in the exemplary embodiment, mixtures of biodiesel with the diesel fraction of the Fischer-Tropsch synthesis are used in a volume ratio of 1: 4 to 4: 1.
  • the fisherman Tropsch diesel exposed to hydrating conditions.
  • the Fischer-Tropsch portion consists of 98 percent by volume paraffinic hydrocarbons with chain length C8 - C24 and a remaining portion of 2 percent by volume olefins with the same chain length distribution.
  • the light hydrocarbon fraction also occurring in the Fischer-Tropsch synthesis with a boiling end ⁇ 200 ° C. is generally not used in the production of fuels.
  • the technical problem underlying the invention is to obtain a largely environmentally neutral, safe, easy-to-produce and storage-stable fuel mixture that meets the requirements of the World Fuel Charter IV for everyday diesel fuel.
  • This task for a diesel fuel of the type mentioned at the outset is achieved in that the light hydrocarbon fraction of the Fischer-Tropsch synthesis is admixed with biodiesel with a boiling end of ⁇ 200 ° C. up to a maximum of 20 percent by weight.
  • the fuel according to the invention is obtained by simple mixing. Both components can be mixed with each other indefinitely.
  • commercial rapeseed methyl esters (RME) and various hydrocarbon boilers from the Fischer-Tropsch synthesis were used for the production. Since the sulfur values for RME and products of the Fischer-Tropsch synthesis are close to the detection limit, a diesel fuel with the lowest possible sulfur content was used in order to obtain comparable results in exhaust gas measurement.
  • the light boiling cut according to the invention from the Fischer-Tropsch synthesis contains 73.1% by volume of n-alkanes, 5.3% by volume of isoalkanes, 12.5% by volume of olefins and 9.0% by volume of alcohols, with a boiling point of 110 ° C and a boiling point of 190 ° C.
  • the one for comparison Heavy Fischer-Tropsch diesel fraction used contains 87.2 percent by volume n-alkanes, 11.7 percent by volume iso-alkanes and 1.1 percent by volume olefins, with a boiling point of 198 ° C and a boiling point of 305 ° C.
  • the cetane number of fuels increases with the proportion of n-alkanes added.
  • the cetane number is a measure of the ignitability of a
  • the required exhaust gas values of the Euro3 standard applicable to the test vehicle are complied with. Surprisingly, the tests carried out show a clear effect in reducing particle emissions. As shown in Table 5, the value measured for the RME-15LF fuel is the determined one Smoke number with 1, 4 well below that of the other fuels. Since all RME-based fuels are considered to be sulfur-free, the value for diesel must be weighted separately at 2.4.
  • the fuel preparation according to the invention also shows a clear jump to lower temperatures when determining the CFPP value. Because of the percentage of alcohols
  • Lubricity-improving additives are required. In the event of an unintentional release, there is hardly any toxic effect on the affected ecosystem in the
  • the RME-15LF fuel produced according to the invention thus shows that, with the same general conditions, clear advantages for diesel engine use in terms of safety, engine load and environmental compatibility are achieved. Against this background, there is an opportunity to establish the light fraction of the Fischer-Tropsch synthesis that has so far not been used as an engine, with broad applicability in the market for diesel fuels.
