Abstract:
This invention disclosure describes a conditioned single phase hydrocarbon-based fuel, a method for producing such fuel and components useful in such method. The described conditioned hydrocarbon-based fuel is a single phase hydrous fuel with improved performance, handling and storage characteristics. A method is also is also provided for producing the conditioned hydrocarbon-based fuel using a semi-solid activator. The resulting conditioned hydrocarbon-based fuel has a volume greater than the unmodified hydrocarbon-based fuel, a BTU content greater than the BTU content of the unmodified hydrocarbon-based fuel, less particulate emissions and less non-particulate emissions than the unmodified hydrocarbon-based fuel, and a water content less than the water content of the unmodified hydrocarbon-based fuel.
Abstract:
Multi faceted technology for the combustion and transportation of emulsified hydrocarbon fuel. The fuel comprises a composite of a plurality of hydrocarbon in water emulsions. The composite emulsion has a unimodal hydrocarbon particle distribution, with the hydrocarbon being present in an amount of between 64% and 90% by volume.
Abstract:
A water-in-hydrocarbon emulsion includes a water phase, a hydrocarbon phase and a surfactant, wherein the water phase is present in an amount greater than or equal to about 5% vol. with respect to volume of the emulsion, and the water phase and the surfactant are present at a ratio by volume of the water phase to the surfactant of at least about 1. A method for preparing the emulsion is also provided.
Abstract:
A method to reduce NOx, emissions from diesel fuel alcohol microemulsions (E-diesel) is taught. Ethanol is stripped from the microemulsion and entered into the exhaust gasses upstream of the reducing catalyst. The method allows diesel engines to meet new, lower emission standards without having to carry separate fuel and reductant tanks.

Abstract:
A water-in-fuel emulsion composition containing a Fischer-Tropsch derived fuel and water, and its use in a compression ignition engine is provided. Emissions, for example of NOx, black smoke and/or particulate matter, are lower as compared to conventional fuels but without lengthening the ignition delay and reducing the cetane number. This is achieved without the need for, or at reduced levels of, ignition improving additives, and without engine modifications.
Abstract:
The invention relates to an emulsified fuel, comprising a major fraction of an emulsion of water and liquid hydrocarbons with a weight ratio of water/hydrocarbons of 5/95 to 35/65, characterised in containing an emulsifying system with at least 15% by weight of a fatty acid ester and polyoxyalkylated glycerol with at least one component of the group formed by the esters of fatty acids and sorbitan and the products of condensation of a succinic acid or anhydride with at least one amine, polyamine, fatty acid, polyoxyalkylated fatty acid, alcohol, polyoxyalkylated alcohol and mixtures of the above. The invention further relates to a method for production of such an emulsified fuel, a composition of emulsifying additives for such an emulsified fuel, a method for improvement of the thermal stability of an emulsified fuel by means of use such an additive composition, as well as the use of such an emulsified fuel as engine fuel.
