Abstract:
Devices, methods and system for combustion of an intimate emulsion of water-in-fuel without the use of chemical additives in order to reduce emissions and improve fuel economy with little or no engine or boiler de-rating or modifications. Apparatus and method for producing, combusting, storing and reducing viscosity of a fuel comprised of water and oil or other hydrocarbons, which is constituted as an emulsion without the need for chemical stabilizers by exposure to constant cavitation.
Abstract:
Heavy oil emulsions, comprising decant oils and No. 6, No. 5 and No. 4 oils, and water are stabilized by adding certain saccharide-based esters. Preferably, the saccharide-based esters are naturally-occurring saccharide esters such as gallotannins, saponin, red gum, and the like.
Abstract:
A method of treating a liquid made up of an initial alcohol-blended fuel combined with water so that there is phase separation of an alcohol-water layer. A co-solvent is added to the first quantity of liquid and mixed with the first quantity of liquid to reverse the phase separation of the alcohol-water layer.
Abstract:
In one aspect, the present invention provides a water-in-oil emulsion comprising from about 5 to about 40 wt % aqueous phase and from about 95 to about 60 wt % non-aqueous phase, said aqueous phase being dispersed in said non-aqueous phase in the form of droplets having an average droplet size no greater than about 0.1 μm, said emulsion comprising: at least 60 wt % of an oil selected from fuel oils, lubricating oils and mixtures thereof, from about 1 to about 30 wt % of emulsifying agents, and the balance to 100 wt % water, wherein said emulsifying agents include a fatty (C8-C24)-amido-(C1-C6)alkyl betaine, is useful as a fuel, coolant or lubricant. In another aspect the present invention provides one or more stable, clear, water-in-fuel microemulsion-forming surfactants may be used in a liquid fuel or oil which is immiscible with water to: a) scavenge free-water which exists in or is introduced into the liquid fuel or oil thereby to render or retain the liquid fuel or oil in a usable state; and/or b) inhibit the growth of aquatic micro-organisms in the liquid fuel or oil when the fuel or oil becomes contaminated with free-water thereby to retain the liquid fuel or oil in a usable state.
Abstract:
[Object] To provide an oil emulsion which can be readily ignited using a conventional, commercially available burner without need of a specific type of device and which has a high ratio of water to an oil and is inexpensive.[Solving Means] An oil emulsion is obtained by mixing under agitation an oil, an emulsifier and a specific type of water obtained by initially passing water through an ion exchange resin, passing either tourmaline or a silicon dioxide-rich rock selected among igneous rocks and further passing the other. The oil emulsion obtained by mixing the oil, the emulsifier and the water is inexpensive and is able to maintain a stable emulsified state.
Abstract:
An emulsified liquid fuel utilizes minor proportions of petroleum, maximum proportions of water (H2O) and minimal amounts of acetone and alcohol, all readily available, plentiful and inexpensive.
Abstract:
An apparatus and process for production of a liquid containing fuel that avoid the need to add any extra surfactant and also the need to apply ultrasonic wave energy and attain high stability of minute bubbles, etc. Production apparatus for a liquid containing fuel comprises pump for pressurizing a stored fuel and nanobubble generating unit adapted to inject a liquid containing the pressurized fuel. The apparatus may be equipped with homogenizing means for storing the liquid containing fuel. The process for production of a liquid containing fuel is characterized by sequentially performing storing of a liquid containing fuel in storage means, pressurizing the liquid so as to obtain a high-pressure liquid with a given pressure, injecting the same through a nozzle into a matrix of liquid containing fuel and effecting collision thereof with a wall so that nanobubbles of foreign substance are dispersed in the matrix of liquid containing fuel.
Abstract:
An emulsified biofuel composition comprising: (A) a continuous phase comprising about 50-95 wt % of at least one liquid oil of vegetable or animal origin or mixtures thereof; (B) a water-containing dispersed phase comprising about 1-50 wt % water; (C) about 1-25 wt % of hydroxyl-containing organic compound selected from the group consisting of mono-, di-, tri- and polyhydric alcohols, provided that when a monohydric alcohol is used there is also present at least one of tert-butyl alcohol, at least one C2-C4 alkylene glycol or a mixture of both; (D) about 0.05-10 wt % of at least one emulsifier; wherein the dispersed water-containing droplets have an average particle size of less than about 20 microns. The biofuel is prepared from these components by mixing under high shear conditions, preferably with ultrasonic energy. The emulsifier(s) preferably exhibit a hydrophilic-lipophilic balance of about 8.5 to about 18 and the biofuel includes a cetane enhancer and mixture of an alcohol and mono- or poly-alkylene glycol.
Abstract:
One or more stable, clear, water-in-fuel microemulsion-forming surfactants may be used in a liquid fuel or oil which is immiscible with water to: a) scavenge free-water which exists in or is introduced into the liquid fuel or oil thereby to render or retain the liquid fuel or oil in a usable state; and/or b) inhibit the growth of aquatic micro-organisms in the liquid fuel or oil when the fuel or oil becomes contaminated with free-water thereby to retain the liquid fuel or oil in a usable state.
Abstract:
The invention relates to a process for manufacturing emulsified fuels by using “oily water” that is proceeded by following steps: (1) preparing the “oily water” that has 0.02—30% (w/w) of combustible fuels dissolved in water and is blended with surfactants (or called as emulsifiers) by 0.01˜3% (w/w); (2) primarily mixing the emulsified “oily water with surfactants”, that was finished by step (1), with 60˜95% (w/w) of heavy fuel oil (abbreviation as heavy oil) or with 75˜98% (w/w) of diesel, respectively; and (3) keeping the mixtures that were finished by step (2), respectively, and mixed up further by using homogenizer to become an “oily water emulsified heavy oil” (OWEH) or an “oily water emulsified diesel” (OWED).
