Abstract:
The use of imidazolium salts (I) where R1 and R3 are each independently an organic radical having 1 to 3000 carbon atoms, R2, R4 and R5 are each independently hydrogen or an organic radical having 1 to 3000 carbon atoms, X is an anion and n is the number 1, 2 or 3 as additives for fuels, especially as detergent additives for diesel fuels, as wax antisettling additives for middle distillate fuels and as lubricity improvers, and for improving the use properties of mineral and synthetic nonaqueous industrial fluids.
Abstract:
Micronized polymers suitable for use in fuels and lubricants having a particle size distribution of less than 30 microns obtained from water-soluble solid organic polymers is provided. A water-soluble solid organic polymer having a number average molecular weight in the range of 1000 to 200,000 is subjected to a molecular segmentation in a polar solvent in a polymer to solvent ratio in the range of 1:1 to 1:10 to produce a micronized polymer having a particle size distribution of less than 30 microns.
Abstract:
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.
Abstract:
Disclosed are additive compositions for superior quality diesel and biodiesel fuels for improving the lacquering resistance of fuels, in particular those intended for engines provided with Euro 4 to Euro 6 fuel injection systems. The additive compositions include at least one antioxidant of hindered phenol type and at least one metal passivator.
Abstract:
An additive mixture for fuels including a) at least one N-formal, b) at least one antioxidant and c) at least one corrosion inhibitor. The additive mixture ensures that the additized fuels and lubricants have biocidal and corrosion-inhibiting additization, especially when they include proportions of renewable raw materials, such as biodiesel, and when they are in contact with copper-containing surfaces.
Abstract:
A method is described for reducing nitrogen oxides in the exhaust gas flow of combustion engines, especially a motor vehicle internal combustion engine, wherein an air/fuel mixture in the combustion chamber of the combustion engine is combusted in the presence of a fuel additive and, in the process, the fuel additive decomposes and the exhaust gas flow is guided through at least one catalyst arranged downstream of the combustion chamber. This method is characterized in that a fuel additive is used, which decomposes in the combustion chamber releasing ammonia and the exhaust gas flow containing ammonia is guided through at least one SCR catalyst arranged downstream of the combustion chamber to reduce the concentration of the nitrogen oxides contained therein. The method according to the invention is highly effective in reducing the nitrogen oxide content in the exhaust gas flow of a combustion engine without an exhaust gas aftertreatment system having to be expensively formed and the installation space having to be increased.
Abstract:
The present invention generally relates to oil compositions, primarily to fuel oil and petroleum compositions produced there from susceptible to wax formation at low temperatures, to polymeric imides for use with such fuel oil compositions, and to methods for their manufacture.
Abstract:
A group of tertiary amine azides are useful as hypergolic fuels for hypergolic bipropellant mixtures. The fuels provide higher density impulses than monomethyl hydrazine (MMH) but are less toxic and have lower vapor pressures that MMH. In addition, the fuels have shorter ignition delay times than dimethylaminoethylazide (DMAZ) and other potential reduced toxicity replacements for MMH.
