Definitions

  • Kerosene typically has a boiling point in the range 180 - 230°C.
  • kerosene are used extensively as lamp oils but are also used absorbed on charcoal as a fuel for lighting barbecues. Traditionally, these preparations have been formulated with added colouring and/or fragrance components essentially to deodorise or mask the characteristic hydrocarbon smell.
  • kerosene for most purposes is not generally susceptible to being successfully thickened.
  • US-A-3795556 describes a self-igniting incendiary material containing an organo-metallic compound, a liquid hydrocarbon fuel and a gelling agent, the resulting composition being capable of self-ignition over water.
  • US-A-3232720 describes a solid shaped fuel product such as a briquette containing a normally liquid hydrocarbon and a normally solid high molecular weight polymer of a 1-olefin having from two to eight carbon atoms.
  • the Journal of Applied Polymer Science, Vol.12, 1968, pp. 55-69 describes the experimental use of high-shear viscometric data for polymer characterisation, using polyisobutylene in various solvents including toluene, kerosene, decalin and gas oil.
  • a method of thickening liquid hydrocarbon fuel oils comprises mixing the hydrocarbon with an essentially paraffin polyolefin polymer in solid form to yield a thickened homogenous liquid solution, characterised in that the liquid hydrocarbon comprises commercial low odour kerosene having a flashpoint greater than or equal to 62°C and the polymer has a molecular weight in the range 1.4 to 2.0 x 10 6 .
  • a composition of matter comprises a thickened homogenous liquid solution of an essentially paraffin polyolefin polymer in solid form dissolved in a liquid hydrocarbon fuel oil, characterised in that the liquid hydrocarbon comprises commercial low odour kerosene having a flashpoint greater than or equal to 62°C and the polymer has a molecular weight in the range 1.4 to 2.0 x 10 6 .
  • the product of the invention may be used as a lamp oil but may also be applied to charcoal for use as a lighting fuel for barbecues, for which it is superior to unthickened hydrocarbon fuels as such in providing better adhesion and absorption of fuel onto the charcoal and also in providing enhanced burning times and burn rates.
  • Additive materials for the deodorising, colouring and/or enhancement of the product perception may be mixed with the inventive composition while still remaining with the terms of the lamp oil directive.
  • the liquid hydrocarbon comprises commercial kerosene having a boiling point in the range 180 - 230°C.
  • the kerosene is a low odour kerosene having a flashpoint greater than or equal to 62°C, typically 63 to 68°C.
  • the polyolefin polymer may be a medium or high molecular weight polymer of an alkene, preferably a branched chain alkene such as polyisobutylene. In polymerisation of such polymers, the olefinic unsaturation is removed except at the terminal moieties.
  • the molecular weight is in the range of 1.4 to 2.0 (viscosity average x 10 6 ), a suitable polymer being commercially available under the trade name 'Vistanex', such as 'Vistanex MML-120'.
  • a suitable polymer being commercially available under the trade name 'Vistanex', such as 'Vistanex MML-120'.
  • Such compounds which are generally used as plasticisers, resemble uncured natural and synthetic rubbers in their physical properties and, when mixed with a hydrocarbon solvent according to the present invention, the polymer initially swells in volume as it appears to imbibe the solvent.
  • the polymer is ground to form granules or particles before being added to the solvent, the individual granules or particles thereof eventually breaking up and becoming dissolved and homogenous in the solvent. The higher is the surface area to volume ratio of the granules or particles, the faster will be the rate of dissolution.
  • a thickened kerosene formulation contains the following ingredients: Material %W/W Low Odour Kerosene 90 - ⁇ 100 typically 95 Polyolefin polymer (Vistanex MML-120) Up to 5 typically 2.5 Fragrance material (optional) Up to 5 typically 2.5
  • Such a formulation has the following properties: Density 0.75 - 0.80 gm/ml @ 20°C typically 0.78 gm/ml Flash point 62 - 66°C typically 63 - 65°C
  • the formulation can be used as a lamp oil.
