Abstract:
Compositions including a fuel soluble ferrocene compound and a fuel soluble solid carrier are disclosed. Methods of preparing tablet forms of the compositions are also disclosed. The fuel soluble ferrocene compound may be ferrocene and/or ferrocene derivatives. The compositions are useful for handling and rapidly solvating the fuel soluble ferrocene compound in a fuel such as gasoline.
Abstract:
This invention is a fuel composition having a sulphur content of /= 50 ppm by weight of at least one fused polycyclic aromatic compound which has at least one hetero-atom selected from O and N either (a) as a heterocyclic group, or, (b) as an exocyclic group in which the hetero-atom is attached either directly or through one other carbon atom to a ring carbon atom wherein the fused polycyclic aromatic compound is substituted on at least one of its ring carbon atoms by a C1-C4 alkyl group. These compounds are capable of improving the antiwear and lubricity properties of a low sulphur fuels, especially diesel fuels, when compared with the performance of the same fuel in the absence of such compounds.
Abstract:
The present invention relates to processes and additive compositions capable of performing at least one of the following: a) stabilizing asphaltenes flocculated and/or precipitated in a petroleum product (as a crude oil, a residue or a fuel oil), rendering thus possible its blending with other petroleum products or its processing or its combustion; b) reducing fouling in petroleum apparatuses; c) achieving yield increase in petroleum refining and/or petrochemical operations; d) reducing particulate and/or SOx and/or NOx emissions during combustion of fuels; e) reducing fouling and/or coke formation in catalysts; f) favouring cleaning and/or decoking of petroleum apparatuses; g) reducing fouling arising from diesel and biodiesel fuels.
