Definitions

  • the present invention relates to the selective removal of metallic contaminants from diesel fuels containing lubricity enhancers.
  • Metals and metal-containing species may be present in fuels such as diesel fuels and jet fuels. Such species may be present as contaminants, their effect on the performance and use of the fuel usually being seen as detrimental. Alternatively, the species may be deliberately added to the fuel to provide a specific function or performance benefit.
  • Metal contamination in fuels is known to cause operational problems.
  • the presence of part-per-billion levels of copper can promote auto-oxidative degradation of the fuel in the presence of oxygen.
  • the presence of low levels of metal contamination in fuels can also lead to fuel degradation and has recently been linked to an increase in the formation of fuel injector deposits in diesel engines.
  • metals such as zinc and lead can give rise to operational problems.
  • metal-containing species In the case of diesel engines fitted with a particulate trap, it is common for metal- containing species to be added to the fuel used to feed the engine. These species are able to catalyse the combustion of soot in the particulate trap thereby regenerating the trap. Iron and cerium are commonly used for this purpose.
  • the metal-containing species may be added to bulk fuel or dosed into the fuel as required.
  • Fuels such as diesel fuel will normally be treated with various chemical additives each designed to provide specific function or performance benefit.
  • a lubricity enhancer For environmental reasons the refining operations to produce modern diesel fuels aim to reduce the level of sulphur-containing compounds to low values. As is known in the art these refining operations also remove compounds which provide diesel fuels with lubricity. Consequently, lubricity enhancers must be added to diesel fuels in order to restore their lubricity and avoid operational problems. Lubricity enhancers are invariably added to bulk fuel by the refiner. Suitable additive chemistries will be known to those in the art.
  • WO2006/108854 describes how metal contamination in a fuel for a compression-ignition engine can be removed by contacting the fuel with a metal-absorbing or metal-adsorbing material which is in a different physical phase from the fuel. It is preferred that the levels of copper, iron and zinc are reduced. Benefits described include a reduction in the incidence of injector deposit formation.
  • the metal-absorbing or metal-adsorbing material may be any of an extremely large range of materials. Included are: fibrous clay minerals, diatomaceous earths, graphite, charcoal, polymeric adsorbents or absorbents, ion-exchange resins and complexing or chelating agents.
  • fibrous clay minerals are those containing sepiolite, attapulgite or palygorskite such as "Fuller's Earth".
  • diatomaceous earths are given as DAMOLIN ® MOLER and HYFLO ® SUPER CEL.
  • polymeric materials are commercial materials such as AMBERL ⁇ ® XAD-4, AMBERL ⁇ ® XAD-7 and AMBERLITE ® XAD- 16.
  • complexing or chelating agents are amines, amides, porphyrins, sulphur materials, carboxylates, oxygen species such as alcohols, ketones, phenols and ethers, cryptands and oxazoles all in solid form or bound to a solid.
  • Preferred ion-exchange resins are sulphonate and carboxylate functionalised resins such as those sold under the tradenames AMBERLITE ® , AMBERLYST ® , DOWEX ® and SEPHADEX ® .
  • Worked examples are given for Attapulgite (a clay), DAMOLIN ® MOLER, AMBERLITE ® XAD-7 and AMBERLYST ® 15. All materials are shown to be effective to reduce the levels of a range of metals in fuel.
  • WO2006/108854 discusses that lubricity enhancers can be present in the fuel either prior to or after contact with any metal-absorbing or metal-adsorbing material however, this is only exemplified by adding a lubricity enhancer to a fuel after metals have been removed.
  • lubricity enhancers can be present in the fuel either prior to or after contact with any metal-absorbing or metal-adsorbing material. Only a specific type of material has been found to be effective to remove undesirable metal contamination from a fuel without having a detrimental effect on the performance of any lubricity enhancer which may be present.
  • the practice of the present invention allows for the effective removal of undesirable metal contamination from fuels such as diesel fuels without adversely affecting the performance of any lubricity enhancers present.
  • beneficial metals such as cerium and iron are not removed to a significant extent and so are able to perform their intended function in the fuel.
  • the present invention provides a method of removing copper, lead or zinc-containing species from a diesel fuel which contains, in addition to at least one of those species, a lubricity enhancer, the method comprising contacting the fuel with an ion- exchange medium represented by the following formula:
  • Q represents a solid support
  • L represents an optional linking group
  • R 1 and R 2 may be the same or different and represent hydrocarbyl groups which may be saturated or unsaturated, linear or branched, substituted or unsubstituted, and wherein the lubricity of the diesel fuel after contact with the ion-exchange medium is not substantially different .from the lubricity of the diesel fuel prior to contact with the ion-exchange medium.
  • the term "not substantially different from” in relation to the lubricity of the diesel fuel before and after contact with the ion-exchange medium should be understood as meaning that, within the accepted tolerances of the test used to measure lubricity of the fuel, the results obtained for a particular fuel sample before and after contact with the ion-exchange medium would not be considered by the skilled worker to be statistically different.
  • the term “without adversely affecting the lubricity” in relation to the second aspect of the invention described hereinbelow should be understood similarly.
  • the lubricity of the fuel be determined by the HFRR test according to
  • both R 1 and R 2 represent the -CH 2 - group.
  • any iron and/or cerium-containing species which may be present in the fuel are not substantially removed.
  • metal-species added to the fuel for beneficial effect are removed. It will be understood however that some removal of such species may be inevitable.
  • the use of the term "not substantially removed" in relation to any iron or cerium-containing species means that although some removal is permitted this should not be such that the beneficial effect of the metal-containing species of interest is lost.
  • treatment of the fuel using the method of the present invention should not affect the ability of the species to catalyse the trap.
  • the solid support may be any solid support commonly used for ion-exchange applications.
  • Q may comprise oxidic materials such as silica, alumina, zirconia, yttria and the like, either in essentially pure form or doped, natural or synthetic zeolites, organic resins such as styrene- divinylbenzene copolymers, polystyrene/divinylbenzene matrices, natural or synthetic fibres or cloths and similar.
  • oxidic materials such as silica, alumina, zirconia, yttria and the like, either in essentially pure form or doped, natural or synthetic zeolites, organic resins such as styrene- divinylbenzene copolymers, polystyrene/divinylbenzene matrices, natural or synthetic fibres or cloths and similar.

  • L represents an alkyl moiety such as methyl, ethyl, propyl, butyl, glycidyl or an alkyl-ether (e.g. (CH 2 ) 3 ⁇ CH 2 CH(OH)CH2 and similar).
  • alkyl-ether e.g. (CH 2 ) 3 ⁇ CH 2 CH(OH)CH2 and similar.
  • the ion-exchange medium comprises an iminodiacetic acid group bound to the solid support via a propyl linking group.
  • Ion-exchange media comprising an iminodiacetic acid group are commercially available. As received these will often be in the form of a sodium salt and as such require conversion to the acid form prior to use. Methods to achieve this will be known to those skilled in the art.
  • Metal contamination of hydrocarbon liquids such as hydrocarbon fuels may result from various causes.
  • components made from copper/lead/zinc-bearing alloys are often used in fuel handling systems, fuel storage tanks and interconnecting pipes.
  • the opportunities for dissolution of small quantities of metals into fuels are thus widespread.
  • Metals can enter into the fuel within the distribution chain which can involve movement of bulk quantities of fuel by ship, barge, road tanker, rail car or pipeline. Contamination can occur from any of the storage or transportation vessels into which the fuel is placed, including those used at fuel filling station forecourts. Once the fuel is dispensed into a vehicle it can pick up metal contaminants from the fuel tank, distribution system and interconnections within this system.
  • the fuel distribution system will incorporate a recycle line which has the function of returning a portion of the fuel provided to the fuel injection system to the fuel tank. As this returned fuel is hot, it has a greater propensity to dissolve metals resulting in metal contamination of the fuel remaining in the fuel tank. It has been reported that a 'clean' fuel containing 6ppb by weight of copper contamination at the point of dispatch, arrived at its destination with a copper level in excess of 60ppb by weight (see “Copper contamination of Jet fuel from ships' heating coils", 6 th International Conference on stability and handling of liquid fuels, Vancouver, Oct. 13-17, 1997)
  • metal-containing species may be deliberately added to fuels to perform a specific function. It is known to use fuel additives containing metals as catalysts to aid with the regeneration of particulate traps. Such fuel-borne catalysts work by becoming entrained with soot particles deposited on a filter situated in the exhaust system of an engine. The presence of catalytic metals allows the soot to combust at a lower temperature than would ordinarily be possible. Commonly used are iron and cerium-containing additives.
  • Fuel-borne catalyst additives are required to be in a form to allow complete dispersion or dissolution into the fuel.
  • One method is to provide the additive in the form of a colloidal suspension of a metal-containing compound. Cerium oxide is often provided in this form.
  • Another option is to produce a fuel-soluble organo-metallic compound. Iron or cerium may conveniently be provided in this form.
  • metal-containing species in fuels may be in the form of insoluble particulates or soluble compounds or complexes.
  • various metal-containing species of interest in the context of the present invention include both species which are metallic and those where the metal constituent is in compounded form.
  • the amount of metal-containing species present in fuels is typically low, particularly for metals which are seen as contaminants; copper, zinc and lead. Representative levels will be in the order of 5 parts-per-billion (ppb) to 20 parts-per-million (ppm) based on the weight of the fuel and the weight of metal in the metal-containing species, for example 5 ppb to 5 ppm or 5 ppb to
  • Levels may be higher for metals which are added to perform a specific function such as fuel-borne catalysts.
  • iron may be present at a level of 1 to 100 ppm, preferably 1 to 50 ppm, for example 1 to 30 ppm.
  • Cerium may be present at a level of 1 to 200 ppm, preferably 1 to 100 ppm, for example 1 to 60 ppm. Values are again based on the weight of the fuel and the weight of metal in the metal-containing species.
  • lubricity enhancers for diesel fuels will be known to those skilled in the art. Commonly used are fatty acids and mixtures of fatty acids and their ester and salt derivatives.
  • the lubricity enhancer comprises a fatty acid or a mixture of fatty acids, an amine salt of a fatty acid or a mixture of fatty acids or an ester of a fatty acid or a mixture of fatty acids.
  • the lubricity enhancer comprises a fatty acid or a mixture of fatty acids.
  • the lubricity enhancer comprises an amine salt of a fatty acid or a mixture of fatty acids.
  • Di-n-butylamine is a preferred amine.
  • lubricity enhancers are added to diesel fuels in amounts ranging from 20 to 500 ppm by weight based on the weight of the diesel fuel.
  • the diesel fuel is a petroleum-based diesel fuel.
  • Such fuels generally boil within the range of from HO 0 C to 500 0 C, e.g. 15O 0 C to 400 0 C.
