Abstract:
An iron-containing polymer is provided for use as a fuel additive for promoting trap regeneration. The polymer shows a beneficial balance of physical properties, and is prepared from iron salts by a polymerization process involving base addition, and subsequent co-ordination of branched-chain polycarboxylate ligands. The polymer can be stored in highly concentrate form, and shows particular suitability for on board dosing systems.
Abstract:
The invention relates to a device for dispensing a liquid additive into a fuel circulation circuit for an internal combustion engine, comprising a reservoir (12) of liquid additive allowing an additive to be distributed into the fuel circulation circuit by means of a distribution line (16), characterized in that it comprises an additive chamber (22) in communication with the fuel circulation circuit and at least one wall (32) that is mobile and fluidtight between said additive chamber and the additive reservoir which, on the one hand, provides a fluidtight division and, on the other hand, maintains equal pressure between the additive in the additive reservoir and the fuel in the additive chamber.
Abstract:
A method of coloring a substrate is disclosed that includes the steps of dissolving a vegetable oil ester based solvent wherein the ester is selected from a group consisting of esters having carbon chain length of C-1 to C-18 in a liquid solvent dye to form a low-sulfur containing dye formulation such that the vegetable oil ester is present in an amount of between about 5 and 80 percent by weight of the dye formulation, and mixing sufficient amounts of the dye formulation with the substrate to produce mixtures of predetermined color in which the levels of toxic substrate are substantially less than in otherwise equivalent mixtures that include hydrocarbon-based solvents.
Abstract:
Described are catalyst compositions and methods for their preparation and use. Certain catalyst compositions can include at least one reduction catalyst and at least one oxidation catalyst. A catalyst composition as described herein is useful in providing certain benefits to a combustible fuel, such as, for example, reducing harmful emissions and/or improving overall fuel economy.
Abstract:
An environment friendly writing instrument that includes a hollow body, an ink reservoir at the first end of the hollow body to hold ink, and a felt tip which extends from the reservoir to the second end of the hollow body, and a dye formulation comprising (I) a vegetable oil ester in an amount of between about 5 and 80 percent by weight of the dye formulation, (ii) a liquid solvent dye present in the dye formulation in an amount sufficient to impart a predetermined color to the dye formulation and (iii) sulfur in an amount of less than about 10 ppm, and wherein the ink is formed from the dye formulation.
Abstract:
A method of improving the combustion of a fuel by adding a catalyst or combustion enhancer at an extremely low concentration, preferably in the range of 1 part catalyst per 200 million parts fuel to 1 part catalyst per 6 trillion parts fuel. The catalyst or combustion enhancer may be selected from a wide range of soluble compounds. The method may comprise the steps of an initial mixing of the catalyst or enhancer with a suitable solvent and then subsequent dilution steps using solvents or fuel. Suitable solvents include water, MTBE, methylketone, methyisobutylketone, butanol, isopropyl alcohol and other hydrophilic/oleophilic compounds.
Abstract:
A safe, metal-containing combustion additive and a method of formulation is directed for use in connection with utility and industrial furnaces. The additive includes a metal-containing catalyst, a ligand for complexing with the catalyst and a solvent for carrying the catalyst/ligand complex. The vapor pressure of the additive is less than about 200×10−5 Torr at 100° F.
Abstract:
A diesel fuel additive is provided that includes a plant oil extract, β-carotene, and jojoba oil. The additive may be added to any diesel fuel to reduce emissions of undesired components during combustion of the fuel. A method for preparing the additive is also provided.
Abstract:
Disclosed is a fuel additive concentrate having a high flash point which is characterized by a viscosity controlled for dosing in a Bernoulli feed device. The concentrate is high temperature stable and is in a form suitable for on-board dosing of fuel which can provide predictable feed rates from a feed device. It comprises a fuel soluble platinum group metal composition and/or a fuel soluble or dispersible cerium composition and/or a fuel soluble or dispersible iron compound and a high flash aromatic solvent. The solvent and the metal composition or compositions are present in relative amounts to provide a FBC concentrate having a flash point (ASTM D93-85) of greater than 140° F. and, a preferred kinematic viscosity within the range of from 7 to 25 centistokes, as measured by ASTM D445 at 105° F.
