Abstract: A fuel composition comprising a Fischer-Tropsch derived middle distillate fuel and a middle distillate flow improver, the remainder being another fuel component or mixture of fuel components. The other fuel component is selected from petroleum derived middle distillate fuel, hydrogenated vegetable oil, fatty acid methyl esters, and other Fischer Tropsch products. The Fischer-Tropsch derived middle distillate fuel is more than 80% v/v of the total composition; the maximum weight content in the carbon number distribution of the n-paraffins in the Fischer-Tropsch derived middle distillate fuel is below C16 and the weight ratio of iso to normal paraffins in the Fischer-Tropsch derived middle distillate fuel is 3.5:1 or higher. The middle distillate flow improver is a substituted ethylene polymer.

Abstract: Gasoline fuel composition suitable for use in an internal combustion engine comprising: (a) Fischer-Tropsch derived naphtha at a level from 2 to 20% v/v; (b) at least one aromatic octane booster present at a level of 0.75 to 8% v/v or less; and (c) a gasoline base fuel; wherein the gasoline fuel composition comprises 40% v/v or less of aromatics. In a preferred embodiment, the Research Octane Number (RON) of the gasoline fuel composition is increased while maintaining the aromatic content of the gasoline fuel composition at a level of 40% v/v or less, based on the gasoline fuel composition.

Abstract: Diesel fuel composition suitable for use in an internal combustion engine comprising: (a) 2 mass % to 30 mass % of kerosene having a kinematic viscosity at 40° C. of 1.5 mm2/s or less and a density of 810 kg/m3 or less; (b) 2 mass % to 20 mass % of Fischer-Tropsch derived base oil having a kinematic viscosity at 40° C. of 7.5 mm2/s or greater and a density of 790 kg/m3 or greater; and (c) diesel base fuel. The diesel fuel composition of the present invention provides improved cold flow properties while simultaneously maintaining other properties such as viscosity and density within diesel fuel specification requirements.
