  • Publication number: 20030005622
    Abstract: The present invention relates to a liquid synfuel additive composition which is used as an additive to coal fines to enhance the complete combustion of the coal after turning it into a synthetic fuel. The composition is a chemical change agent in that it converts the coal/composition mix into a different material which, when burned, results in lower noxious emissions. The composition includes a wax, a base for ph adjustment and water.

  • Patent number: 5746783
    Abstract: A method and matter of composition for controlling NO.sub.x emissions from existing diesel engines. The method is achieved by adding a small amount of material to the diesel fuel to decrease the amount of NO.sub.x produced during combustion. Specifically, small amounts, less than about 1%, of urea or a triazine compound (methylol melamines) are added to diesel fuel. Because urea and triazine compounds are generally insoluble in diesel fuel, microemulsion technology is used to suspend or dissolve the urea or triazine compound in the diesel fuel. A typical fuel formulation includes 5% t-butyl alcohol, 4.5% water, 0.5% urea or triazine compound, 9% oleic acid, and 1% ethanolamine. The subject invention provides improved emissions in heavy diesel engines without the need for major modifications.

  • Patent number: 5404841
    Abstract: The present invention relates to a process for reducing nitrogen oxides emissions from a diesel engine, which comprises preparing an emulsion of an aqueous urea solution in diesel fuel, and supplying said emulsion to a diesel engine for combusting therein, whereby combustion of the emulsion leads to a reduction in the nitrogen oxides emissions from the diesel engine when compared with combustion of diesel fuel alone.

  • Patent number: 5360458
    Abstract: This invention provides for water-oil emulsions comprising water, oil and a minor emulsifying amount of the reaction product of: (A) at least one saturated or unsaturated aliphatic monocarboxylic acid of about 12 to about 24 carbon atoms; (B) at least one acid of the general formula C.sub.19 H.sub.n COOH, wherein n is a number in the range of about 27 to about 31, and having a phenathrene nucleus; and (C) at least one amine. In one hydroxy embodiment, the oil employed in these emulsions can be any oil, the water content of these emulsions being up to about 30% by weight. In a preferred embodiment, the oil employed is crude oil. These emulsions can be facilitatingly pumped through a conduit even when the oil employed is a viscous crude oil. These emulsions are useful as a combustible fuel when the water content is below about 30% by weight.

  • Patent number: 5176814
    Abstract: A heat source, may be on a high speed vehicle, may be cooled by transferring thermal energy from the heat source to an endothermic fuel decomposition catalyst in order to heat the catalyst to a temperature sufficient to crack or dissociate at least a portion of an endothermic fuel stream. The endothermic fuel is selected from the group consisting of normal paraffinic hydrocarbons and methanol. The heated endothermic fuel decomposition catalyst is contacted with the endothermic fuel stream at a liquid hourly space velocity of at least about 10 hr.sup.-1 to cause the endothermic fuel stream to crack or dissociate into a reaction product stream.
