Definitions

  • Bx fuels may be derived entirely from animal or vegetable oil sources (B100 fuels) or they may comprise a proportion of fuels derived from animal or vegetable oil sources, admixed with fuels from other sources (for example mineral sources, or synthetic sources, e.g. Fischer-Tropsch sources).
  • B20 herein is a fuel in which 20 wt% of the fuel is from animal or vegetable oil sources and 80 wt% of the fuel is from other sources. The proportion may be lower still, as in the case of, for example, a B5 fuel.
  • WO 2007/076163 describes such problems, and suggests that the problem of filter blocking arises as a result of the precipitation of crystals of steryl glycosides in fuels derived from biological sources. Steryl glycosides are found in plants and it is suggested that they are carried over into Bx fuels.
  • WO 2007/076163 proposed a solution to the filter blocking problem; namely the removal of the steryl glycosides, for example using an adsorbent as an additive in conjunction with a process of filtration or centrifugation, or both.
  • soy biodiesel was filtered through a bed of diatomaceous earth.
  • mineral fuels herein we mean fuels derived wholly from mineral (i.e. petroleum) sources.
  • mineral fuel component herein we mean the mineral-derived component in a Bx fuel.
  • Filter blocking problems can occur at temperatures below the cloud point in mineral and other fuels. Such problems have been closely analysed over many years. Additives have been developed that allow fuels to be used at lower temperatures than would otherwise be possible.
  • the source of the problem of precipitation below the cloud point is the presence of components such as so-called “waxes” (for example n-alkanes and methyl n-alkanoates that crystallise at low temperatures). This may cause the fuels to block filters and to become non-pourable.
  • waxes for example n-alkanes and methyl n-alkanoates that crystallise at low temperatures. This may cause the fuels to block filters and to become non-pourable.
  • Standardised tests have been devised to measure the temperature at which the fuel hazes (the cloud point - CP), the lowest temperature at which a fuel can flow (the pour point - PP) and the cold filter plugging point - CFPP); and the changes thereto caused by additives ( ⁇ CP, ⁇ PP, ⁇ CFPP).
  • the standardised tests for measuring PP and, especially, CP and CFPP are among the common working tools for persons skilled in the art. CP and CFPP may be further described as follows:
  • the cloud point of a fuel is the temperature at which a cloud of wax crystals first appears in a liquid when it is cooled under conditions prescribed in the test method as defined in ASTM D 2500.
  • US 5743923 describes the improvement of the low temperature properties of a blend of biofuel and petroleum based fuel oil by addition of an ethylene-unsaturated ester copolymer, a comb polymer, a polar N compound or a a compound having at least one linear alkyl group connected to a non-polymeric organic residue.
  • WO2007/147753 describes a paraffin dispersant for fuels, especially having a biodiesel content comprising polar oil-soluble nitrogen compounds and acid amides.
  • WO96/22344 describes chemical markers as additives in fuel oil compositions to improve filterability at temperatures above its cloud point.
  • US2008/0016754 describes additive mixtures as cold flow additives for middle distillate fuels comprising a terpolymer of ethylene, propene and at least one ethylenically unsaturated ester and a further additive selected from copolymers of ethylene and ethylenically unsaturated compounds, comb polymers and mixtures thereof.
  • CFIs cold flow improvers
  • WASAs wax anti-settling additives
  • Some such additives may assist in keeping the so-called “waxes” in solution in the mineral fuel; others may alter their crystal morphology or size, so that filterability and pourability are maintained in spite of precipitation.
  • Additives are also known which improve the CFPP of Bx grades, including B100 grade, and thus it would be expected that fuels treated in this way should have no operating problems even at temperatures significantly below the CP of the fuels.
  • the precipitate does not redissolve when the temperature is raised again. This is very different to conventional wax precipitation where at temperatures above the cloud point, wax can readily redissolve, particularly if kept dispersed in the fuel through use of WASAs.
  • a reaction product of (i) a compound containing the segment -NR 1 R 2 where R 1 represents a group containing from 4 to 44 carbon atoms and R 2 represents a hydrogen atom or a group R 1 , and (ii) carboxylic acid having from 1 to 4 carboxylic acid groups or an acid anhydride or acid halide thereof, in order to improve the filterability of a Bx fuel above the cloud point of the Bx fuel; wherein the Bx fuel comprises fuel derived from animal or vegetable oil sources admixed with fuel derived from mineral or synthetic sources; wherein the Bx fuel has a sulphur content less than 200ppm; wherein the Bx fuel contains at least 4 wt% of fuel derived from animal or vegetable sources; and wherein the additive is present in the Bx fuel in an amount (as active material) of from 10 mg/kg up to 200 mg/kg.

In the case of a hydrocarbyl group R 1 having from 11 up to 20 carbon atom it may contain up to two unsaturated bonds. In the case of a hydrocarbyl group R 1 having from 21 up to 30 carbon atom it may contain up to three unsaturated bonds. In the case of a hydrocarbyl group R 1 having from 31 up to 40 carbon atom it may contain up to four unsaturated bonds.

  • the additive may be added to Bx fuel which is known to exhibit a filtration problem above the cloud point, to reduce the problem or, preferably, to obviate the problem by preventing precipitation above the cloud point.
  • Reducing or solving the problem may be achieved by reducing the size or quantity of the precipitates which may appear in the Bx fuel above the cloud point, or by controlling the morphology of the precipitates in the Bx fuel above the cloud point.
  • the additive is added to Bx fuel in order to prevent the emergence of precipitates above the cloud point.
  • preventing the emergence of precipitates above the cloud point we mean that detectable precipitates do not appear in the Bx fuel under normal storage or use conditions.
  • an additive which is the reaction product of (i) a compound containing the segment -NR 1 R 2 where R 1 represents a group containing from 4 to 44 carbon atoms and R 2 represents a hydrogen atom or a group R 1 , and (ii) a carboxylic acid having from 1 to 4 carboxylic acid groups or an acid anhydride or acid halide thereof in order to prevent the emergence of precipitates in the Bx fuel above the cloud point of the Bx fuel.
  • a sample of the fuel to be tested is passed at a constant rate of flow through a glass fibre filter medium.
  • the pressure drop across the filter is monitored, and the volume of fuel passing the filter medium within a prescribed pressure drop is measured.
  • the filter blocking tendency (FBT) can be described in one of the following ways:
  • the FBT is 1.41.
  • Values of FBT >1.41 indicate that less than 300 ml pass through the filter before a pressure of 105 kPa is reached.
  • Values Of FBT ⁇ 1.41 indicate that 300ml pass through the filter at a pressure of less than 105kPa
  • the modification to the IP 387 method relates to thermal conditioning and cold soak of a sample being tested.
  • the base fuel used in these tests was a B5 fuel which met the requirements of DIN EN 590 and contained a commercially available cold flow additive believed to comprise EVA copolymers in an amount effective to achieve a CFPP of ⁇ -15°C.
  • Example Set B the testing was the same as in Example Set-A but the base fuel ("Basefuel 2") also met the requirements of DIN EN90 and was a B10 fuel prepared from a standard diesel meeting the specifications of CEC Fuel Specification RF-06-03, blended with rapeseed methyl ester (RME) and a commercially available cold flow additive believed to comprise EVA copolymers in an amount effective to achieve a CFPP of ⁇ -15oC.
  • Basefuel 2 base fuel
  • RME rapeseed methyl ester
