Definitions

  • This invention relates to fuel compositions comprising an anti-foam additive to reduce the time needed to break up any foam formation during the filling of a vehicle's fuel tank thereby enabling a more complete filling of the tank and at the same time reducing risk of spillage.
  • the problem of foaming of fuels due to entrainment of air during filling of fuel tanks of vehicles is well known.
  • the problem has hitherto been mitigated by adding to the fuel antifoams which are substantially non-hydrocarbonaceous.
  • An example of such a non-hydrocarbonaceous additive is a silicon containing polymer.
  • Non-hydrocarbonaceous additives usually have to undergo a rigorous testing programme with respect to their compatibility with the fuel and also environmental considerations. However, if the additive is a hydrocarbon, especially a non-aromatic hydrocarbon, the issues of compatibility and environmental considerations are not as critical.
  • JP-A-08073870 discloses gasoline compositions for two-cycle engines which contain at least 10 vol % 7-8C olefinic hydrocarbons and have a Tso of 93-105°C, a final distillation temperature of 110-150°C and an octane No. by the motor method of at least 95.
  • 11 olefins listed 2,4,4-trimethyl-1-pentene.
  • these olefins are used as a blend of several.
  • the olefins are not used as anti-foaming agents but to achieve high output and low fuel consumption and to avoid seizure even at high compression ratios.
  • gasoline used in two-cycle engines ie two-stroke engines
  • SAE Paper 950740 describes various compounds being added to a mixture of toluene (boiling point about 110°C) and isooctane (boiling point 99°C) to monitor the emissions of vehicles powered therewith.
  • One such compound added is di-isobutylene in an amount > 15% by volume. The resultant mixture is unlikely to have a final boiling point above 150°C and there is no mention of the use of di-isobutylene as an anti-foam in this document.
  • JP-A-06200263 describes a composition which contains at least 65% by volume based on the total base fuel of a high boiling component with a boiling point from 80-120°C which uses 7-8C paraffin type or olefin type hydrocarbon.
  • the abstract of this patent makes no mention of any other base fuels or specific olefins in this range and there is no mention of any of such olefins as anti-foaming agents.
  • WO 99/49003 discloses gasoline formulations which contain, inter alia, at least 5% by volume of saturated C 7 /C 8 branched chain hydrocarbons. In any event, there is no mention of the use of these as anti-foaming agents.
  • the present invention provides the use of di-isobutylene as an anti-foam for a base fuel as defined in claim 1 of the set of claims following this description.
  • Optional and/or preferred features of the invention are defined in the other claims in the set of claims following this description.
  • the base fuels may comprise mixtures of saturated, olefinic, and aromatic hydrocarbons, and these can be derived from straight run streams, thermally or catalytically cracked hydrocarbon feedstocks, hydrocracked petroleum fractions, catalytically reformed hydrocarbons, or synthetically produced hydrocarbon mixtures.
  • the present invention is particularly applicable to a broad range of petroleum fuels from the light boiling gasoline (which typically boils between 50 and 200°C) to distillate fuel (which typically boils between 150 and 400°C).
  • the most common distillate fuels suitable for use in the present invention as base fuels are selected from motor gasoline, kerosene and diesel fuels.
  • the sulfur content of the base fuel is suitably less than100 ppm by weight, preferably less than 50 ppm by weight and more preferably less than 30 ppm by weight.
  • Such low sulfur levels can be achieved in a number of ways. For instance, this may be achieved by well known methods such as, e.g., catalytic hydrodesulfurization.
  • Di-isobutylene used as an anti-foam in accordance with the use of the invention is employed in an amount greater than 2.5% by volume based on the total fuel composition, suitably up to 35% by volume, preferably less than 15% by volume, more preferably from 5.0 to less than 15% by volume, still more preferably from 7.5% to less than 15% by volume of the total fuel composition.
  • Di-isobutylene can readily be obtained by dimerization of isobutylene. It is generally prepared from a crude mixture of olefins and usually contains a mixture of various C 8 -olefin isomers but always comprises 2,4,4-trimethylpent-1-ene admixed with 2,4,4-trimethylpent-2-ene. These two isomers are suitably present in the di-isobutylene in a weight ratio of about 75% (-1-ene) to about 25% (-2-ene).
  • Di-isobutylene has an advantage over other non-hydrocarbonaceous anti-foams such as silicon based polymers in that di-isobutylene is substantially miscible with conventional fuels in all proportions.
  • Di-isobutylene has the further advantage that current plants making methyl tert-butyl ether (hereafter "MTBE") from isobutylene and methanol (MTBE having more recently fallen out of favour upon environmental considerations), can be readily switched to convert the same isobutylene feedstock to di-isobutylene.
  • MTBE methyl tert-butyl ether
  • MTBE methyl tert-butyl ether
  • MTBE methyl tert-butyl ether
  • MTBE methyl tert-butyl ether
  • MTBE methyl tert-butyl ether
  • MTBE methyl tert-butyl ether
  • MTBE methyl tert-butyl ether
  • Tests were carried out in which di-isobutylene (a mixture of 3 parts 2,4,4-trimethylpent-1-ene and 1 part 2,4,4-trimethylpent-2-ene) was added to varying quantities to a distillate fuel which was susceptible to foam formation.
  • di-isobutylene a mixture of 3 parts 2,4,4-trimethylpent-1-ene and 1 part 2,4,4-trimethylpent-2-ene
