Definitions

  • This invention relates to cerium oxide nanoparticles which are useful as fuel supplements.
  • Cerium oxide is widely used as a catalyst in three way converters for the reduction of toxic exhaust emission gases and the reduction in particulate emission in automobiles.
  • the ceria contained within the catalyst can act as a chemically active component, working as an oxygen store by release of oxygen in the presence of reductive gases, and removal of oxygen by interaction with oxidising species.
  • Cerium oxide may store and release oxygen by the following processes :-
  • Cerium oxide may provide oxygen for the oxidation of CO or C n H n or may absorb oxygen for the reduction of NO x .
  • the amounts of oxygen reversibly provided in and removed from the gas phase are called the oxygen storage capacity (OSC) of ceria.
  • OSC oxygen storage capacity
  • the above catalytic activity may occur when cerium oxide is added as an additive to fuel. However, in order for this effect to be useful the cerium oxide must be of a particle size small enough to remain in a stable dispersion in the fuel.
  • the cerium oxide particles must be of a nanocrystalline nature, for example they should be less than 1 micron in size, and preferentially'! -3 OOnm in size. In addition, as catalytic effects are surface area dependant the small particle size renders the nanocrystalline material more effective as a catalyst.
  • the incorporation of cerium oxide in fuel serves more than one purpose. The primary purpose is to act as a catalyst in the reduction of toxic exhaust gases on combustion of the fuel. However, it can serve another purpose in diesel engines. Diesel engines increasingly comprise a trap for particulates resulting from combustion of the diesel fuel. The presence of the cerium oxide in the traps helps to burn off the particulates which accumulate in the trap. Indeed such a use is in commercial operation.
  • the present invention has applicability particularly in relation to two-stroke engines which are fuelled by a mixture of gasoline and lubricating oil; such engines are particularly useful in motor cycles and snowmobiles, outboards and portable power equipment such as chain saws.
  • the cerium oxide to the lubricating oil which forms only a small proportion of the fuel it is possible to dose the cerium oxide particles more accurately than if they are added to the final fuel.
  • the present invention provides a method of improving the efficiency of a fuel for an internal combustion engine, which fuel comprises gasoline and a lubricating oil, which comprises adding to the fuel or the oil cerium oxide and/or doped cerium oxide.
  • the present invention also provides a lubricating oil composition which comprises, apart from the lubricating oil, cerium oxide and/or doped cerium oxide as well as a fuel comprising such a lubricating oil composition and gasoline.
  • a lubricating oil composition which comprises, apart from the lubricating oil, cerium oxide and/or doped cerium oxide as well as a fuel comprising such a lubricating oil composition and gasoline.
  • the ceria serves as the oxygen activation and exchange medium during a redox reaction.
  • ceria and the like are ceramic materials, they have low electronic conductivity and low activity surface sites for the chemisorption of the reacting species. Transition metal additives are particularly useful to improve this situation.
  • multivalent dopants will also have a catalytic effect of their own.
  • the doped oxides will have the formula Ce 1 .
  • M is a said metal or metalloid, in particular Rh Cu, Ag, Au, Pd, Pt, Sb, Se, Fe, Ga, Mg, Mn, Cr, Be, B, Co, V and Ca as well as Pr, Sm and Gd and x has a value up to 0.3, typically 0.01 or 0.1 to 0.2, or of the formula M' is a said metal or metalloid other than a rare earth, RE is a rare earth, y is 1 or 1.5 and each of n and k, which may be the same or different, has a value op to 0.5, preferably up to 0.3, typically 0.01 or 0.1 to 0.2. Copper is particularly preferred.
  • the cerium oxide particles will have a size not exceeding 1 micron and especially not exceeding 300 nm, for example 1 to 300 nm, such as from 1. to 150 nm, in particular 2 to 50 nm, especially 2 to 20 nm . It is preferred that the particles are coated to prevent agglomeration.
  • the particles can be comminuted in an organic solvent in the presence of a coating agent which is an organic acid, anhydride or ester or a Lewis base. It has been found that, in this way which involves coating in situ, it is possible to significantly improve the coating of the oxide. Further, the resulting product can, in many instances, be used directly without any intermediate step.
  • the cerium oxide can be dispersible or soluble in the (liquid) fuel or another hydrocarbon compatible with the fuel.
  • the particles which are subjected to the process should have as large a surface area as possible and preferably the particles have a surface area, before coating, of at least 10 m /g and preferably a surface area of at least 50 or 75 m /g, for example 80- 150 m 2 /g, or l00-300m 2 /g.

  • the coating agent is preferably an organic carboxylic acid or an anhydride, typically one possessing at least 8 carbon atoms, for example 10 to 25 carbon atoms, especially 12 to 18 carbon atoms such as stearic acid, It will be appreciated that the carbon chain can be saturated or unsaturated, for example ethylenically unsaturated as in oleic acid. Similar comments apply to the anhydrides which can be used. A preferred anhydride is dodecenylsuccinic anhydride.
  • Other organic acids, anhydrides and esters which can be used in the process of the present invention include those derived from phosphoric acid and sulphonic acid.

  • the solvent is non-polar and is also preferably non-hydrophilic. It can be an aliphatic or an aromatic solvent. Typical examples include toluene, xylene, petrol, diesel fuel as well as heavier fuel oils.
  • the organic, solvent used should be selected so that it is compatible with the intended end use of the coated particles. The presence of water should be avoided; the use of an anhydride as coating agent helps to eliminate any water present.
