Abstract: A method of preparing agglomerates of ultra-fine coal particles includes mixing a film forming agglomeration aid (FFAA) with a quantity of ultra-fine coal particles to form ultra-fine coal particles coated with the FFAA. The FFAA has a lower surface energy relative to a surface of the ultra-fine coal particles. The FFAA is mixed with the ultra-fine coal particles in an amount less than 3% by weight of the ultra-fine coal particles on a dry basis. Agglomerates of the ultra-fine coal particles coated with the film forming agglomeration aid are formed using vibration, pelleting, and/or briquetting. The agglomerates have a size of at least 2 mm. The ultra-fine coal particles have a particle size less than 100 µm. The agglomerate has a tumbler test friability less than 3%. The drop shatter friability is also less than 3%.

Abstract: A gaseous combustible fuel includes a gaseous hydrocarbon fuel feedstock and solid fuel particles suspended in the gaseous hydrocarbon fuel feedstock. The solid fuel particles have a sufficiently small particle size so that they remain suspended during transportation. The hydrocarbon fuel feedstock may include natural gas, ethane, propane, butane, and gaseous derivatives and mixtures thereof. The solid fuel particles may include coal-derived solid carbonaceous matter. Other examples of solid fuel particles include biomass, refined bioproducts, and combustible polymer particles. The gaseous combustible fuel has an energy density at atmospheric pressure which is at least 25 % greater than the volumetric energy density of the gaseous hydrocarbon fuel feedstock. Improvements in volumetric energy density of 50 %, 100 %, and even 500% are disclosed. The gaseous combustible fuel may be pressurized to a pressure in the range from 2 to 100 atmospheres.

Abstract: A transportable and combustible gaseous suspension includes solid fuel particles suspended in a gaseous carrier. The solid fuel particles have a sufficiently small particle size so that they remain suspended during transportation. The gaseous carrier may include reactive and inert gases. The solid fuel particles may include coal-derived solid carbonaceous matter. Other examples of solid fuel particles include biomass, refined bioproducts, and combustible polymer particles. The combustible gaseous suspension can be tailored to have an energy density at atmospheric pressure which is comparable to conventional gaseous hydrocarbon fuels. The gaseous combustible fuel may be pressurized to a pressure in the range from 2 to 100 atmospheres.

Abstract: Coal-derived mineral matter captures or removes combustion gas emissions from flue gas. The coal-derived mineral matter may be obtained by separating it from coal particles, such as by use of a flotation separation process. Coal-derived mineral matter may also be present in fine coal refuse. In the disclosed method, an aqueous suspension of coal-derived mineral matter particles is contacted with the combustion gas emissions for sufficient time to cause the combustion gas emissions to react with the aqueous suspension and form an enhanced aqueous suspension. The combustion gas emissions may comprise NOx, SOx, CO, or mixtures thereof. An aqueous suspension of coal-derived mineral matter particles containing enhanced amounts of soluble and insoluble sulfate, sulfite, nitrate, nitrite, or carbonate reaction compounds formed by reaction of the aqueous suspension of the coal-derived mineral matter particles with combustion gas emissions.

Abstract: Coal fines are processed by flotation separation to separate coal particles from ash-forming component particles. Coal fines are mixed water under high shear mixing conditions to form an aqueous slurry of coal fines containing between 15 wt.% and 55 wt.% coal fines. The aqueous slurry is introduced into a coal flotation cell to separate coal particles from ash-forming component particles by flotation separation, wherein the coal fines have a particle size less than 500 µm, and more preferably less than 300 µm. Bubbles are generated in the coal flotation cell having a bubble size and bubble quantity selected to float the coal particles and to form a coal-froth containing at least 15 wt.% solid particles. The solid particles include coal particles and ash-forming component particles. The coal-froth is collected for further processing.
