  • Process for preparing a diesel fuel composition
    Patent number: 11084997
    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.
