Abstract:
Compositions and methods of using same are described for negating asphaltene deposition in a formation, wellbore, near wellbore region, and production tubing. Compositions of the invention comprise an asphaltene solvent and a viscosity reducing agent, the asphaltene solvent and viscosity reducing agent present in a ratio so as to substantially reduce viscosity of an asphaltene-containing material while substantially negating deposition of asphaltenes either in a reservoir, in production tubing, or both when mixed or otherwise contacting the asphaltene-containing material. Methods of the invention comprise forcing a composition comprising an asphaltene solvent and a viscosity reducing agent to contact an asphaltene-containing hydrocarbon in an underground geologic formation, and producing from the formation a production composition comprising at least some of the treatment composition and at least some of the asphaltene-containing hydrocarbon under conditions sufficient to substantially negate deposition of asphaltenes in the formation.
Abstract:
Biofuels suitable for use in an internal combustion engine contain ethanol and are denatured with a performance-enhancing component. The performance-enhancing denaturant component includes an organic ingredient selected from the group consisting of friction modifiers, lubricity enhancers, anti-oxidants, and combinations thereof. An internal combustion engine fueled by such a biofuel has improved engine performance, including: increasing lubricant oil lubricity, reducing lubricant oil degradation, increasing engine component durability, and/or combinations thereof. In certain aspects, methods of increasing fuel economy are provided. The present disclosure also provides methods of formulating such biofuels.
Abstract:
A fuel additive contains ferrocene and/or ferrocene derivative(s), and lecithin. A fuel additive contains 80 to 99 mass % of ferrocene and/or ferrocene derivative(s), and 1 to 20 mass % of lecithin, and being in the solid state. A fuel additive contains 78 to 99 mass % of ferrocene and/or ferrocene derivative(s), 0.9 to 20 mass % of lecithin and 0.1 to 2 mass % of water, and being in the particle state. A fuel additive containing 2 to 5 mass % of ferrocene and/or ferrocene derivative(s), 5 to 50 mass % of lecithin and mineral oil, and being in the liquid state, wherein the ferrocene and/or ferrocene derivative(s), and the lecithin are dissolved in the mineral oil. The above-mentioned fuel additive is used by being added into a fuel so as to make the concentration of the ferrocene and/or ferrocene derivative(s) and the lecithin in ranges of 1 to 50 ppm, and 0.01 to 500 ppm, respectively.
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 polymerisation process involving base addition, and subsequent coordination 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 present application provides a method for reducing fouling, including particulate-induced fouling, in a hydrocarbon refining process including the steps of providing a crude hydrocarbon for a refining process; adding an additive selected from: wherein R1, R2, R3, and R4 are independently selected from a branched or straight-chained C5-C80 alkyl group, and M1, M2, and M3 are independently selected from Ca, Mg and Na.
Abstract:
The primary purpose of this present invention is to provide a product that can replace gasoline in spark ignition, internal combustion engines. More particularly, the invention relates to a method for lowering the oxidizing properties of Ethanol that will allow it to function without destroying engine parts.
Abstract:
A method is disclosed for reducing the freezing point of unleaded aminated aviation gasoline to −58° C. or lower by the addition of tert-amylphenylamine.
Abstract:
