  • Emulsion with coke additive in hydrocarbon phase and process for preparing same
    Patent number: 6384091
    Abstract: A process for preparing a hydrocarbon in water emulsion includes the steps of providing a hydrocarbon phase containing inactive natural surfactant; mixing a solid carbon additive with the hydrocarbon phase, the solid additive being selected from the group consisting of coal, coke and mixtures thereof so as to provide a hydrocarbon suspension including the solid carbon additive; and forming an emulsion from the hydrocarbon suspension and an aqueous phase in the presence of a surfactant activating additive so as to activate the inactive natural surfactant and form a hydrocarbon in water emulsion having the solid carbon additive suspended in the hydrocarbon phase. A hydrocarbon in water emulsion is also provided including a hydrocarbon phase, a water phase, a surfactant, and a solid carbon additive suspended in the hydrocarbon phase, the solid carbon additive being selected from the group consisting of coal, coke and mixtures thereof.

  • Emulsion with solid additive in hydrocarbon phase and process for preparing same
    Patent number: 5964906
    Abstract: A process for preparing a hydrocarbon in water emulsion includes the steps of: providing a hydrocarbon phase containing a contaminant selected from the group consisting of vanadium, sulfur, and mixtures thereof; mixing a solid additive with the hydrocarbon phase, the solid additive being selected from the group consisting of calcium compounds, magnesium compounds and mixtures thereof so as to provide a hydrocarbon suspension including the solid additive; and forming an emulsion from the hydrocarbon suspension and an aqueous phase including a surfactant so as to form a combustible hydrocarbon in water emulsion having the solid additive suspended in the hydrocarbon phase.
