Abstract:
The inventive colloidal dispersion comprised cerium compound particles, an acid and an organic phase and is characterized in that it also comprises a compound of at least one element selected from rhodium and palladium. According to variants, the dispersion comprises particles of a compound of cerium, another rare earth and/or iron. The inventive dispersion can be used as an additive to diesel fuels for diesel engines
Abstract:
A method of reducing smoke and particulate emissions from steam boilers and process heaters operating on solid fuel by adding a fuel additive which contains an oil-dispersible iron compound and an over-based magnesium compound to the solid fuel.
Abstract:
The invention relates to an emulsified water in oil composition using a novel additive surfactant package containing a PIBSA-derived surfactant with a molecular weight in the ranged about 300 to 3000 and in the range of about 0.01% to about 10% by weight of the composition and an alkylamine ethoxylated surfactant in the range of about 0.01% to about 10% by weight of the composition.
Abstract:
Fuel additives, fuel formulations, and processes for their preparation and use are provided. The additives improve the combustion properties of hydrocarbon fuels. The enhanced combustion indicates reductions in certain emissions.
Abstract:
A process for removal of sulfur dioxide from a flue gas. An alkaline admixture is coated with a coating agent that improves dispersability and delays calcination of the alkaline admixture within a combustion zone and results in a coated alkaline admixture. The coated alkaline admixture is introduced to the boiler to create a reaction that reduces the amount of sulfur dioxide from the flue gas.
Abstract:
The present invention relates to an additive composition for a combustible fuel to utilize readily available and renewable resources and to produce improved combustion and reduced smoke and particulate production of the combusted fuel, which additive composition comprises: a. one or more water-soluble alcohols selected from the group consisting of alcohols having from between about 1 and 6 carbon atoms, in an anhydrous state or as a 0.5-36% aqueous solution, and one or more of the following: b. one or more alcohols selected from the group consisting of clear, liquid saturated or unsaturated, straight- or branched-chain alcohols having from between about 6 and 18 carbon atoms; c. one or more alcohols selected from the group consisting of ethoxylated straight- or branched- long-chain alcohols having between about 12 and 18 carbon atoms, where the ethylene oxide add-on is less than 5 moles; d. a fatty acid of the structure R—(C═O)—OH, wherein R is selected from alkyl, alkenyl or alkynyl having from about 10 to 24 carbon atoms, with e. a source of nitrogen in an anhydrous state or as an aqueous solution selected from the group consisting of the ammonia, hydrazine, alkyl hydrazine, dialkyl hydrazine, urea, ethanolamine, monoalkyl ethanolamine, dialkyl ethanolamine wherein alkyl is independently selected from methyl, ethyl, n-propyl or isopropyl wherein trialkylamines are excluded; wherein components a to e when combined with mixing with said combustible fuel form a clear stable microemulsion having a viscosity similar to a liquid fossil fuel; and wherein said additive composition excludes glycerine, polyethylene, polyoxyethylene, polyoxypropylenes, aromatic organic compounds, sulfur, sulfur compounds, metals, metal compounds, compounds of phenanthrene. Speeifically, compositions of ethanol, methanol, iso-propanol, octanol, 2-ethyl-hexanol, linoleic acid, oleic acid, ammonia, and water are preferred to produce minimum smoke, particulates, and noxious gases upon combustion.
Abstract:
A fuel or fuel additives is disclosed which comprise particles of cerium oxide which have been doped with a divalent or trivalent metal or metalloid which is a rare earth metal, a transition metal or a metal of group IIA, IIIB, VB, or VIB of the Periodic Table.
Abstract:
The invention relates to a liquid fuel composition comprising: 10-80 vol % of a first component comprising at least two aliphatic organic non-hydrocarbon compounds; 20-65 vol % of a second component comprising at least one hydrocarbon and having an aromatic content of less than 15 vol % of the total of the second component; 1-35 vol % of a third component, which comprises an oxygenate; and 0.01 to 20 vol % water, wherein at least one compound in the fuel composition is miscible with both water and hydrocarbons to provide a single phase composition. Such fuels have been found to reduce undesirable emissions in the exhaust gases and enable the use of recycled compounds and water in the fuel.
Abstract:
A fuel additive is directed to preventing slagging, a phenomenon caused by the ash in a fuel particularly during the combustion of a fuel having such a large ash content as is typically found in coal or oil coke, for example. It is formed of a composition having one or more compounds selected from among aluminum compounds, silica compounds, titanium compounds and zirconium compounds invariably of the form of ultrafine particles having a particle diameter in the range of 3 to 200 nm and no less than 2 wt. % of an alkali metal (RnullNa or K) compound as reduced to the R2O concentration dispersed in a stable state in water and/or oil. When a liquid fuel oil and/or a solid fuel is made to incorporate the fuel additive therein and then subjected to combustion, the deposited ash can be easily peeled and shed from the surface of the furnace wall or the water pipes.
Abstract:
There is described a fuel composition which is substantially free of alkoxylated compounds and is substantially free of long-chain alkyl alcohols having at least 6 C atoms, and contains at least 95% by volume of a hydrocarbon-based fuel and 0.1 to 5% by volume of an additive of the formula (I); RnullCOnullNR1R2 (I) in which R is a saturated or unsaturated, linear or branched alkyl radical having 6 to 21 C atoms; and R1 and R2, which may be the same or different, each represent a hydroxyalkyl radical having 1 to 4 atoms.
