Abstract: Process for preparing a diesel fuel composition comprising the steps of: (i) blending a Fischer-Tropsch derived gasoil with a petroleum derived gasoil to form a blended gasoil which is compliant with the EN590 specification, wherein the Fischer-Tropsch derived gasoil has a density of 0.8 g/cm3 or less and wherein the petroleum derived gasoil is derived from naphthenic high density petroleum crude oil and has a density at 15° C. of 0.84 g/cm3 or greater and a naphthenics content of 30 wt % or greater; and (ii) mixing the blended gasoil produced in step (i) with a diesel base fuel to form a diesel fuel composition, wherein the diesel fuel composition has a density at 15° C. in the range from 0.820 g/cm3 to 0.845 g/cm3.

Abstract: A liquid fuel composition for a spark ignition internal combustion engine comprising (a) gasoline blending components, (b) Fischer-Tropsch derived naphtha at a level of up to 50% v/v and (c) oxygenated hydrocarbon at a level less than 50% v/v. While the low octane number of Fischer-Tropsch derived naphtha would normally severely restrict its blendability in gasoline to low levels, it has now been found that Fischer-Tropsch derived naphtha can be included in, for example, ethanol-containing gasoline fuel compositions, in surprisingly and significantly high blend ratios of Fischer-Tropsch derived naphtha to ethanol.

Abstract: A gasoline fuel formulation which contains 60% v/v or more of a combination of (a) a biologically-derived alcohol and (b) a mixture of C4 to C12 hydrocarbon fuel components, all of which hydrocarbon fuel components have been derived, whether directly or indirectly, from catalytic conversion of a biologically-derived oxygenate component, wherein the concentration of the alcohol (a) in the formulation is from 0.1 to 30% v/v.
