摘要:
A process to prepare a catalytically dewaxed gas oil or gas oil blending component by performing the following steps:(a) hydrocracking/hydroisomerizing a Fischer-Tropsch product;(b) separating the product of step (a) into at least one or more fuel fractions and a gas oil precursor fraction;(c) catalytically dewaxing the gas oil precursor fraction obtained in step (b); and,(d) isolating the catalytically dewaxed gas oil or gas oil blending component from the product of step (c) by means of distillation.

Use in a gas oil fuel composition, which preferably comprises a Fischer-Tropsch derived fuel, of a compound according to formula (I): wherein: R1 to R4 are each independently hydrogen or a C1-10 alkyl group, where such alkyl groups may be the same as or different from one another; and X is a nitrogen- or oxygen-containing group, for the purpose of reducing the cetane number of said fuel composition; preparation of such a fuel composition; and operating a fuel consuming system.
摘要:
In a fuel composition containing a static dissipator additive, a Fischer-Tropsch derived fuel component is blended for the purpose of increasing the electrical conductivity of the composition and/or for reducing the concentration of the static dissipator additive in the composition. The fuel composition is preferably an automotive diesel fuel composition.

摘要:
Process to blend a mineral derived hydrocarbon product and a Fischer-Tropsch derived hydrocarbon product by providing in a storage vessel of a marine vessel a quantity of mineral derived hydrocarbon product and Fischer-Tropsch derived hydrocarbon product such that initially the mineral derived hydrocarbon product is located substantially above the Fischer-Tropsch derived hydrocarbon product, transporting the combined products in the marine vessel from one location to another location, also referred to as the destination, and obtaining a blended product at arrival of the marine vessel at its destination.
摘要:
A diesel fuel formulation is disclosed containing a water-in-fuel emulsion of (a) a Fischer-Tropsch derived gas oil, optionally in combination with conventional diesel, (b) a fatty acid alkyl ester in an amount of at least 1% v/v and (c) water. An emulsifier may be present.Formulations have useful emissions properties and retain performance characteristics in spite of the presence of water.Methods of preparing the formulations and their uses are also described.
摘要:
A process to prepare an aviation fuel and an automotive gas oil from a source of mineral derived gas oil is provided. From the mineral derived gas oil a low boiling fraction is isolated for use as an aviation fuel or as an aviation fuel component and the remaining part of the mineral derived gas oil is blended with a Fischer-Tropsch derived kerosene fraction and/or a Fischer-Tropsch derived gas oil fraction to obtain a blend suited for use as at least part of an automotive gas oil.
摘要:
A fuel composition is provided containing (i) a base fuel, (ii) a Fischer-Tropsch derived gas oil and (iii) an oxygenate. The components (ii) and (iii) can be used in a tertiary fuel blend with a base fuel (i) for the purpose of achieving for the composition (a) a neutral or close to neutral effect on elastomeric components compared to that of the base fuel, and/or (b) a neutral or better emissions performance (in particular with respect to NOx and/or particulate emissions) compared to that of the base fuel, preferably in addition to a neutral or close to neutral density for the composition with respect to that of the base fuel.
