Abstract:
A method of producing a synthetic fuel by treating fines of bituminous coal with an emulsion of a tall-oil mix, which may include enhancers that either increase the chemical change in the coal or reduce the cost of the synthetic fuel. Enhancers include poly vinyl acetate (PVA) and/or ethyl vinyl acetate (EVA), glycol, lignosulfonate, beet sugar bottoms, corn bottoms, brewery bottoms, vegetable tall oil, vegetable oil, and/or spent frying oil. The emulsion is sprayed into, and reacted with, the coal fines, resulting in a cost effective and industry-usable source of synthetic fuel.
Abstract:
A method of producing a synthetic fuel by treating bituminous coal fines with a tall-oil mix that may include enhancer additives that either increase the chemical change capability of the tall-oil mix or reduce the cost of the tall-oil mix while maintaining the chemical change rate, and/or an additive of tar decanter sludge and light cycle oil. Enhancers include poly vinyl acetate (PVA) and/or ethyl vinyl acetate (EVA), glycol, lignosulfonate, beet sugar bottoms, corn bottoms, brewery bottoms, vegetable tall oil, vegetable oil, and/or spent frying oil. The tall-oil mix is reacted with the coal, resulting in a cost effective and industry-usable source of synthetic fuel. When the enhanced tall-oil mix is reacted with bituminous metallurgical coal, the product is a synthetic fuel.
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.

Abstract:
A pumpable slurry for recovering fuel value from lignin by mixing the lignin with water, fuel oil and a dispersing agent to form a stable thixotropic or near Newtonian portable slurry by coordinating the amounts of lignin, water and fuel oil to produce a substantially slurry suitable for use as a liquid fuel having a viscosity after stirring of 100 to 1,000 mPa.s.
Abstract:
Suspensions of solid particulates in aqueous media, useful, e.g., as thickeners in a wide variety of foodstuff and industrial applications, are sedimentations stabilized by incorporating therein a stabilizing amount of xanthan/carob gum, optionally starch admixture.
Abstract:
A fuel slurry consisting of a hydrocarbonaceous solid, oil and water effectively stabilized against settling of the solid by the addition of an aluminate, silicate, aluminosilicate or a combination of these compounds.
Abstract:
Apparatus for manufacturing a coal-oil-water fuel mixture comprises a grinder for grinding coal to a relatively fine particle size, a mixer for controllably mixing the coal particles with oil, water and a high molecular weight organic mixture. These devices may be used in combination with coal cleaning apparatus for removal of ash and impurities from the coal. The high molecular weight organic compound may be contained in a heavy residual oil containing paraffinic fractions.
Abstract:
Apparatus suitable for making a coal-oil-water fuel mixture includes a grinder for grinding coal to a relatively fine particle size, a mixer for controllably mixing the coal particles with water and oil and a sonic agitator to stabilize the mixture. The sonic agitator comprises a processing chamber associated with or having two opposed plates which are oscillated by appropriate transducers at controllable phase frequency and amplitude. The spacing between the plates is preferably of the order of 500 meters per second divided by the applied sonic frequency, and is at least 25 mm.
Abstract:
The production of fuel comprising an emulsion of coal particles, oil and water or a dispersion of coal and oil in which pyrites, ash and other impurities are removed from the coal particles and the particles reduced in size by forming a slurry of contaminated coal particles and water and exposing that slurry to violent sonic agitation to cause the impurities to be detached from the coal particles and the particles to be reduced in size. The coal and impurities are thereafter separated and the coal subsequently incorporated into a fuel. The process may also be used to separate other minerals which are bonded mechanically as distinct from chemically, to each other.
