| titleOfInvention | Iron-containing polymer for regenerating diesel exhaust particulate traps |
| abstract | A process for preparing an iron-containing polymer for use as a fuel additive comprising the following steps: [i] obtaining/preparing an aqueous solution of one or more iron (III) salts, such as iron (III) nitrate or iron (III) chloride or obtaining/preparing an aqueous solution of either one or more iron (II) salts or a mixture of iron (II) and iron (III) salts: [ia] permitting or causing the oxidation of iron (II) ions to iron (III) ions by exposure to air and/or other oxidising agent: [ii] adding thereto a weak base, such as sodium hydrogen carbonate or ammonium carbonate; [iii] obtaining a wet precipitate, wherein molar ratio of iron to base is in the range 1:2.5-1:3.5; [iv] reacting the wet precipitate in an organic solvent, with a tertiary nitrogenous base, such as triethyl amine, and one or more polycarboxylic acids, such as branched chain isomers of octadecenyl succinic acid, and/or derivatives thereof, such as branched chain octadecenyl-succinic anhydride, branched chain hexadecenyl-succinic anhydride or branched chain polyisobutenyl-succinic anhydride; [v] wherein at least polycarboxylic acid and/or derivative employed in step [iv] comprises a branched chain hydrocarbyl substituent containing at least 14 carbon atoms, and the molar ratio of iron to carboxylic groups in the range 1:1 and 3:1; and [vi] removing the resulting solid polymer material. Also disclosed is an iron-containing polymer consisting of a polymer backbone from which a plurality of co-ordinating ligands depend, the backbone consisting of alternating iron and oxygen atoms in a chain-like structure optionally also bearing hydroxyl groups as pendant or bridging groups, and the co-ordinating ligands being polycarboxylate ligands and optionally also water molecules, wherein the polycarboxylate ligands comprise ligands having branched hydrocarbyl substituent groups containing at least 14 carbon atoms; a fuel composition comprising the iron-containing polymer; a diesel fuel composition comprising the polymer; a method of regenerating a diesel exhaust particulate trap using the fuel composition; and a method of reducing particulate emissions from a diesel comprising use of the fuel composition. |
