Definitions

  • the present invention relates to a synergistic interaction between an overbased calcium sulfonate detergent and an ashless succinimide dispersant that allows for the formulation of improved distillate fuel additive packages.
  • the additive compositions contain an organometallic complex of manganese. Distillate fuels treated with the additive compositions exhibit improved combustion because of the detergent and the organometallic manganese compound and good fuel system cleanliness because of the detergent/dispersant interaction.
  • distillate fuel additive compositions to provide environmental benefits when the fuel is combusted.
  • Such benefits include, for example, reduced emissions of noxious pollutants such as oxides of nitrogen and particulate matter, reduced acidity of emitted particulates, and better fuel economy (which amounts to lower emissions of carbon dioxide per amount of fuel burned).
  • noxious pollutants such as oxides of nitrogen and particulate matter
  • reduced acidity of emitted particulates reduced acidity of emitted particulates
  • better fuel economy which amounts to lower emissions of carbon dioxide per amount of fuel burned.
  • An embodiment presented herein provides a fuel additive composition comprising an organometallic manganese compound, an alkyl-substituted succinimide ashless dispersant, and an overbased calcium sulfonate detergent of TBN above about 200.
  • the TBN of the overbased calcium sulfonate is about 300.
  • Another embodiment provides a fuel comprising a major amount of a middle distillate fuel and a minor amount of a fuel additive composition comprising an organometallic manganese compound, an alkyl-substituted succinimide ashless dispersant, and an overbased calcium sulfonate detergent of TBN above about 200.
  • a method of for improving the cleanliness of a fuel intake systems by use in the fuel intake system of a fuel containing a fuel additive composition comprising an organometallic manganese compound, an alkyl-substituted succinimide ashless dispersant, and an overbased calcium sulfonate detergent of TBN about 300.
  • distillate fuel additive compositions for use in distillate fuels that provide enhanced fuel combustion and, at the same time, superior cleanliness of fuel intake systems.
  • Distillate fuels are defined herein as petroleum-based hydrocarbon fuels boiling in the range of about 140-360°C [284-680°F] and encompass diesel and biodiesel fuels, jet fuels, marine fuels and home heating oils.
  • Distillate fuels containing the additive compositions of the invention show enhanced combustion characteristics.
  • fuels containing the additive packages also show excellent fuel injector cleanliness as measured by the Cummins L10 diesel detergency test. This injector cleanliness is exhibited as an injector rating of at most 10.0 in the Cummins L10 diesel detergency test.
  • inventions herein provide an additive composition, a distillate fuel containing the additive composition, and a method of improving the cleanliness of fuel intake systems by use of the fuel containing the additive composition.
  • the organometallic manganese compound does not affect injector cleanliness.
  • the organometallic manganese compound may be present in the fuel at concentrations of up to about 20 PTB.
  • the amount of organometallic manganese compound was shown to have no significant adverse effect on injector ratings and is therefore not constrained by the model represented by equation 3. As an economic matter only, the amount of manganese compound is, in an embodiment, limited to 20 PTB or less.
  • the benefits derived from the inclusion of a manganese compound are not directly related to injector ratings, but are much more prevalent in the areas of particulate emission reduction, reduced NO x and SO x , reduced hydrocarbons, improved fuel economy, and combustion improvement.
  • MMT® methylcyclopentadienylmanganese tricarbonyl
  • succinimide prepared from 850 to 2100-MW PIBSA and a polyalkylene polyamine approximating tetraethylenepentamine in composition as the ashless dispersant
  • MMT® is available from Ethyl Corporation, Richmond, VA.
  • the diesel fuel used in the Cummins L10 study was a high-sulfur (0.4wgt % sulfur) fuel, but any diesel fuel (including low-sulfur and ultralow-sulfur fuels) may be used.
  • a separate L10 experiment has shown that the addition of 2-ethylhexyl nitrate cetane improver to a fuel containing the inventive additive does not degrade the detergent performance.
  • HiTEC® 4080 Component % weight ppm component at 500 ppm total PTB component at 500 ppm total HiTEC® 9645 15.34 76.7 22.8 2-ethylhexanol 46.22 231.1 68.8 HiTEC® 611 32.16 160.8 47.9 HiTEC® 536 0.93 4.7 1.4 D-5021 0.97 4.9 1.5 HiTEC® 3062 4.38 21.9 6.6
  • the European components D-5021 (demulsifier) and HiTEC® 536 (corrosion inhibitor) were replaced with the North American components Tolad 9310 and 50% dodecenylsuccinic acid, respectively, on an equivalent weight basis. These components were held constant at the above concentrations in every test.
  • the components expected to have significant effects on Cummins L10 ratings were HiTEC® 9645 (a succinimide-based dispersant), HiTEC® 611 (overbased calcium sulfonate) and HiTEC® 3062 (62 % MMT® in aromatic solvent).
  • HiTEC® 3062 and the higher-order terms AC, BC and ABC were significant at less than the 85% confidence level and are therefore excluded.
  • HiTEC® 9645 unexpectedly decreases the CRC response (a beneficial effect, since lower CRC ratings indicate less injector depositing), while HiTEC® 611 increases the ratings.
  • HiTEC® 9645 has a significant negative interaction between HiTEC® 9645 and HiTEC® 611, meaning that the deleterious effect of HiTEC® 611 on CRC rating at low concentrations of dispersant is more than cancelled out at high dispersant concentrations.
  • HiTEC® 611 improves CRC ratings when in the presence of high amounts of HiTEC® 9645. This effect is shown graphically by the interaction diagram in Figure 2.
  • HiTEC® 611 Ordinarily, a p-value of 0.13 would result in HiTEC® 611 alone being excluded from the model: this value indicates that the coefficient is different from zero only at the 87 % confidence level. However, if the model contains an interaction between HiTEC® 9645 and HiTEC® 611, the HiTEC® 611 term should also be included to preserve model hierarchy.
  • any combination of HiTEC® 9645 and HiTEC 611 to the right of the 10.0 contour (the dashed line) in Figure 3 should give a passing Cummins L10 rating.
  • Three points were selected on the 9.0 contour (the solid line) in the L10 test. The additive combinations corresponding to these points were:
  • a simple 2 3 experimental design has determined the quantitative effects of various components in a Greenburn® Diesel Fuel Additive package on Cummins L10 performance. It was found that the succinimide dispersant (HiTEC® 9645) had a beneficial effect on injector ratings, while the overbased calcium sulfonate detergent (HiTEC® 611) harmed those ratings. In addition, a strong interaction between these two components was observed which reduced the undesirable effect of the detergent. MMT® (as HiTEC® 3062) had no significant effect on injector cleanliness. The model derived from the experimental design was used to formulate modified Greenburn®-type packages that passed the Cummins L10 test.
  • each numerical parameter should at least be construed in light of the number of reported significant digits and by applying ordinary rounding techniques. Notwithstanding that the numerical ranges and parameters setting forth the broad scope of the invention are approximations, the numerical values set forth in the specific examples are reported as precisely as possible. Any numerical value, however, inherently contains certain errors necessarily resulting from the standard deviation found in their respective testing measurements. It is intended that the specification and examples be considered as exemplary only, with a true scope and spirit of the invention being indicated by the following claims.
