Definitions

  • the present invention relates to improvements in fuel compositions, and in particular to improving the properties of blended fuel compositions comprising renewable diesel and biodiesel. Due to environmental considerations significant efforts have been made in developing alternative hydrocarbon fuels to fossil fuels to power internal combustion engines.
  • the present invention relates in particular to alternatives to mineral diesel fuel.
  • One alternative fuel suitable for use in diesel engines is biodiesel.
  • Biodiesel is produced by the transesterification of lipids obtained from plants or animals, for example tallow oil, soybean oil or other vegetable oil. Transesterification of the triglycerides obtained from these plant or animal sources with an alcohol such as methanol, ethanol or propanol produces a mono alkyl ester as the biodiesel fuel.
  • Fuel filter pore sizes have therefore decreased and in some cases may be as low as 2 to 5 microns in diameter.
  • the reduction in pore size of the filter has inevitably led to increased issues with filter blocking.
  • a blocked filter will restrict or prevent fuel from reaching an engine. This can cause problems with starting the engine and a loss of power.
  • a blocked filter can cause an engine to shut down altogether until the filter has been replaced, in order to protect the injection system, causing huge inconvenience to the user.
  • the present invention seeks to reduce the filter blocking tendency of fuels containing a blend of renewable diesel and biodiesel fuels.
  • Preferred wax anti-settling additives (d) are derived from copolymers of maleic anhydride and an ⁇ -olefin having 6 to 30 carbon atoms reacted with 2 equivalents of a fatty amine.

  • the amines may be primary, secondary, tertiary or quaternary, but preferably are secondary. Tertiary and quaternary amines can only form amine salts.
