Abstract:
A fuel composition, preferably for use in internal combustion engines, comprising a water-in-oil emulsion of (a) a hydrocarbon fuel, such as gasoline, diesel fuel or fuel oil; (b) water; (c) preferably a water-soluble alcohol; and (d) a novel combination of surface-active agents to provide a clear composition which is stable against phase separation over a wide range of temperatures.
Abstract:
The field of art to which this invention pertains is hydrocarbon based liquid fuel compositions having increased octane number by the use of microemulsion technique. The new composition comprises a main part of a liquid hydrocarbon mixture, water in the form of a microemulsion, an emusifier which makes possible the solubilization of the water in the hydrocarbon mixture and at least one water-soluble inorganic substance which has been dissolved in the water solubilized in the hydrocarbon mixture.
Abstract:
EMULSIFIED FUEL COMPOSITIONS COMPRISING A HYDROCARBON FUEL AS THE DISPERSE PHASE, AN EMULSIFIER, WATER AND UREA OF FORMAMIDE AS AN EMULSION STABILIZER HAVE IMPROVED FLOW AND DEMULSIFICATION CHARACTERISTICS.
Abstract:
A system and device for producing an oil-in-water emulsion of high water-insoluble liquid content, e.g., containing 70 percent to about 95 percent of such liquid or oil. An initial receptacle receives streams of oil, water, and emulsifying agent, while beater means subdivides the oil component and forms such oil-inwater emulsion. An exit portion or chamber and an aperture therein are connected by a conduit to a second or dilution receptable, wherein predetermined amounts of dilution water are introduced and thoroughly admixed with the emulsion. The continuous process for forming such an emulsion includes effecting with the beater a thin, continuous water phase around very small particles of oil, continuously withdrawing a primary thick emulsion to a dilution zone, and continuously diluting it to a desired water or dilution liquid content.
Abstract:
This invention relates to oil-in-water (water continuous) emulsions that can be used as fuels, in particular oil-in-water emulsions comprising glycerol. The invention also relates to a process for their preparation and to fuel compositions comprising such emulsions.
