Abstract:
A method of reducing the negative effects of accumulation of ash in a diesel fuel combustion system includes supplying a diesel fuel having an additive that includes a manganese compound to a diesel fuel combustion system. The combustion system includes a catalyzed diesel particulate filter or, alternatively, a continuously regenerating technology diesel particulate filter. The fuel is then combusted in the combustion system to product at least one byproduct that includes the manganese compound. The manganese compound is supplied in an amount effective to complex with the combustion byproduct.
Abstract:
The present invention relates to an additive for a fuel for the neutralization of SO2 and/or SO3 in the exhaust gases of internal combustion engines operated with the fuel, and a method for the neutralization of SO2 and/or SO3 in the exhaust gases of internal combustion engines. According to the invention, the additive contains one or more metal compounds soluble in the fuel. In the combustion of the fuel these compounds form stable sulfates which are present in solid particles in the exhaust gas. The method of the invention is characterized in that one or more of these additives are added to the fuel and the combustion of the fuel takes place in an oxidizing atmosphere.
Abstract:
A method of improving fuel efficiency in combustion chambers, for simultaneously enhancing combustion of hydrocarbon fuels while inhibiting nitrogen oxidation. A mixture of metallic compounds is introduced into the flame zone of a combustion chamber, such that this mixture is held by gases in the flame zone during the combustion of the fuel, and the mixture is thereby ionized prior to or during the combustion. The ionized mixture of compounds contains platinum, rhodium, rhenium, and molybdenum.
Abstract:
This invention relates to an emission control device containing a catalytic material capable of reducing pollutants in the combustion gases generated from an internal combustion engine, as well as from other combusted solid and liquid fossil fuels such as coal, and is also useful for treating combustion gases generated from the incineration of landfill garbage and tire rubber, among others. The catalytic material of the present invention is highly resistant to deactivation or poisoning from contaminants in the combusted material such as leaded gasoline. The catalytic material predominantly comprises a plagioclase feldspar belonging mainly to the albite-anorthite series and contains small amounts of mica, kaolinite and serpentine, and optionally contains magnetite. A catalytic alloy material is also disclosed, comprising a mixture of the above-described catalytic material and a metal. The alloy material likewise exhibits unique catalytic properties.
Abstract:
The present invention improves flame combustion of liquid carbonaceous fuels by the preparation and use of a fuel additive comprising a finely-divided particulate hydrated compound in stable suspension in a liquid vehicle. The median major dimension of the primary particles of hydrated compound is preferably less than 10 microns. When employed at a level of from about 200 to about 5000 parts per million, the additive can improve the efficiency of combustion and reduce particulate emissions for flame combustion of liquid carbonaceous fuels, especially residual grades of fuel oil.
Abstract:
In the combustion zone of a furnace burning sulphur-containing fuel, one introduces continuously sodium or potassium nitrate; ammonium nitrate; calcium hydroxide and/or magnesium carbonate; carbon; and ammonium carbonate.A neutralization of acidic sulphur compounds formed by the combustion is achieved, and the boiler is kept free from soot and other deposits.
Abstract:
Microorganism induced corrosion of storage vessels which contain a heel of water and an upper layer of hydrocarbon liquid may be prevented by adding to the hydrocarbon liquid contained in such storage vessels a water-dispersible polyvinyl alcohol package which contains a microbiocide.
Abstract:
An anti-pollution heating oil composition includes an organic or inorganic lithium compound in said heating oil to reduce particulate emission upon combustion of said heating oil. A variety of lithium compositions and processes for their use in removal of accumulated carbonaceous deposits are also disclosed.
Abstract:
This invention relates to a composition containing calcium and aluminum, preferably in the ratio Ca/3Al, or calcium and aluminum in combination with Si, preferably in the ratio between about Ca/3Al/2Si and Ca/3Al/4Si (all calculated as metal weights); and to the use of such composition in petroleum fuels which contain vanadium, particularly in combination with sodium, for example in residual fuels so as to inhibit corrosion in the system, particularly in gas turbines. These compositions are superior to magnesium as an additive to such fuels, particularly in fuels which are high in sodium.
