Abstract:
PROBLEM TO BE SOLVED: To provide a method for lowering an amount of carbon in fly ash resulting from combustion of the coal. SOLUTION: This additive and method for reducing the carbon and the fly ash are based on the combustion of a mixture of the coal and a manganese-containing compound. The manganese compound is mixed with the coal before a combustion chamber or in the combustion chamber. The manganese compound may be an inorganic or organometallic compound. The organometallic compound includes methyl cyclopentadienyl manganese tricarbonyl. COPYRIGHT: (C)2005,JPO&NCIPI
Abstract:
An improved diesel fuel based on a blend of biodiesel and ultra-low sulfur diesel fuel, particularly with a fuel additive containing a concentrate containing fuel borne catalyst (FBC). The catalyst will preferably comprise platinum and/or cerium and/or iron, and the ultra-low sulfur diesel fuel will preferably contain less than 10% aromatics. The biodiesel is typically employed in an amount of about 20% of the blend.
Abstract:
A fuel composition of the present invention exhibits minimized hydrolysis and increased fuel stability, even after extended storage at 65° F. for 6-9 months. The composition, which is preferably not strongly alkaline (3.0 to 10.5), is more preferably weakly alkaline to mildly acidic (4.5 to 8.5) and most preferably slightly acidic (6.3 to 6.8), includes a lower dialkyl carbonate, a combustion improving amount of at least one high heating combustible compound containing at least one element selected from the group consisting of aluminum, boron, bromine, bismuth, beryllium, calcium, cesium, chromium, cobalt, copper, francium, gallium, germanium, iodine, iron, indium, lithium, magnesium, manganese, molybdenum, nickel, niobium, nitrogen, phosphorus, potassium, palladium, rubidium, sodium, tin, zinc, praseodymium, rhenium, silicon, vanadium, or mixture, and a hydrocarbon base fuel.
Abstract:
An additive to a flame reaction is provided which forms noncorrosive deposits on cooler metal surfaces which are more stable than Na2SO4 or K2SO4. The additive preferentially combines with the sodium or potassium, and sulfates of these will not be formed. By adding tungsten, tungsten salts or tungsten percursors to the flame, a complex sodium tungstate is produced on the surface of the cooler metal object in a dense form and corrosion is inhibited. The level of tungsten preferably present at an atomic concentration is equal to 1.5 to 2 times that of the sodium in the specific flame environment and possibly a little higher for potassium. The nature of the fuel and possible alkali reduction schemes will control the quantity and mixing method of the additive. The additive may be directly mixed into the fuel or injected into the burned gas regions of the combustion, Ta and Nb also appear as possible substitutes for W in the invention.

Abstract:
Platinum group metal fuel additives are effective in fuel environments which make the exclusion of water impractical. The fuels additives comprise a platinum group metal compound and a water-functional composition selected from the group consisting of lipophilic emulsifiers, lipophilic organic compounds in which water is miscible and mixtures of these. The additives are preferably effective in fuel compositions having water contents of at least about 0.01% water by weight.
Abstract:
The invention provides a method employing a fuel additive to improve the operation of a pass-through oxidation catalyst over long periods of time with continued catalytic activity and without the undesirable conversion of SO.sub.2 to SO.sub.3. A pass-through catalyst support is continuously, selectively catalyzed by the combustion of a fuel containing a platinum group metal composition which burns to release the catalyst metal in active form. The effectiveness of the process is attributed to improved combustion in the engine by the catalyst and the treatment of the catalytic oxidizer with active catalyst metal released during combustion such that, in the exhaust system, the soluble organic fraction of the particulates and the levels of gaseous unburned hydrocarbons and carbon monoxide are significantly reduced. The catalysts conditioned by the present invention cause minimal conversion of SO.sub.2 to SO.sub.3. The platinum group metal compositions soluble or dispersible in the diesel fuel and are added in amounts effective to provide concentrations of the metal in the fuel of less than 1 part per million (ppm).
Abstract:
An improved fuel composition comprising a major amount of hydrocarbons boiling in the gasoline boiling range, and a minor amount of iron pentacarbonyl capable of improving the octane number rating of the composition but insufficient to cause excessive wear in engine parts when the fuel composition is burned in an internal combustion engine.
